1. Problem with DC Motor : Is the motor gone bad ? thanks?

To strengthen on what dmb06851 reported... A variable resistor will, in concept, artwork. whether you will likely have an quite perplexing time looking one with adequate potential skill, and that is extraordinarily inefficient. A switching (PWM = pulse width modulation) velocity administration may well be a much greater constructive selection. in case you are desperate to pursue the backside-shape-fee selection, bypass to an vehicle junkyard and get the countless resistors that are used to regulate the fee of the heater fan in a vehicle. this may not provide you stepless administration, whether it particularly is an hassle-free thank you to get a resistor which will handle a number of amps. pay attention, you should place those resistors in a cooling air circulate or they will dissipate with out delay.

Feeder nerves to muscles from the spine undergo progressive degeneration so that muscle function progressively declines. It gets critical when muscles of respiration, of swallowing, of the larynx also get affected and one has to be on life support, like Stephen Hawking had been. He had a type of MND called Amyotrophic Lateral Sclerosis (ALS)--.

3. How to Connect a Servo Motor Controller and Jog the Servo Motor (Part 1) | AutomationDirect

In this video we will hook up a SureServo system and quickly jog the motor to verify proper operation. You will need a SureServo drive, a SureServo motor, a motor power cable, motor feedback cable, and a power source. Most importantly you should have a copy of the SureServo manual. You can purchase a copy of the manual, or you can download it for free from the automationdirect.com Web site, or the SureServo.com Web site. Hooking up a SureServo systems is easy. The encoder cable connects to the motor lead and to the drive. The motor power cable is connected to the other motor lead and then to the drive with three discrete connections and the ground. Please note that unlike some other three-phase motors the phases for a servo must be connected in the correct order. On a SureServo red is connected to "U" white to "V" and black to "W". The green ground wire has a ring terminal pre-installed and is attached at the bottom front of the drive. If you have a brake motor refer to chapter three for details on connecting the brake leads. Note that all AutomationDirect motor power cables include the brake leads regardless of whether your motor has a brake If your motor has a brake you will need to apply 24 Volt DC to these leads before you can jog the motor. This motor does not have a break so I have just capped these leads. Two types of power connections are required for most Servo systems and SureServo is no exception. The main power connection powers the motor while a second connection powers the control electronics in the drive. In many installations an e-stop circuit is required to disconnect the main power "R", "S" and "T", while control power to the drive can be maintained for diagnostic and maintenance purposes. It is strongly recommended that you implement an e-stop circuit and proper circuit protection. Both for personnel safety and for the protection of the electronics. See chapter three of the manual for recommendations on the size and type of circuit protection for each SureServo system. Most SureServo installations will require Three-phase 220 Volts for the main power. Although the smaller systems will run on Single-phase 220. In this case supply power to "R" and "S" only. The control power only requires single-phase. Just provide 220 volts across the "L1" and "L2" terminals. Double-check your wiring - make sure you've got the required voltage on the correct connectors. Let's power it up. There will be errors alarm fourteen and alarm fifteen are alarm errors for the over travel limit switches see chapter eight for an explanation. The drive is configured for normally closed limit switches by default and we do not have any switches connected, thus, these errors. Now we will set some parameters. First we will set P2-08 to ten. This will reset the drive to factory defaults. Press the mode once then press next until P2-00 appears press the arrow up key until P2-08 is selected, press enter. Then press the arrow up until a value of ten is displayed. Press enter to accept. See chapter four for additional keypad help. Next we will set the appropriate motor code. Because each sure servo drive is capable of controlling several different motors we must tell the drive which motor is connected. We will set P1-31 to eleven for this two hundred watt motor. See chapter five for all of the motor Codes. Now we must cycle power to the drive. Warning: To prevent serious injury or damage to equipment always start any new servo setup with the motor shaft disconnected from the load. In this quick start video we will bypass mechanical over travels Please disconnect the load for the first test of the motor Always wire an e-stop circuit into the power feed for the drive. Always drop the main incoming power for e-stop conditions but remember the control power can remain on. Now we will set parameter P2-30 to one. This temporarily overrides servo enable, clockwise limit, and counterclockwise limits. This parameter will revert to zero if control power is cycled. This feature is purely for testing purposes. You should discreetly wire a Servo enable and over travel limit switches if appropriate for your application. If your application does not require over travels you can disable the respective inputs or use them for another purpose. The motor is now enabled. To jog the motor go to P4-05: Jog Operation. Press Enter. The Jog speed set point is displayed. The default is twenty RPM. Press enter again to enter the jog operation mode. The LED display will show jog. Press the up arrow or the down arrow to jog the motor forward or reverse. Press mode to return to the jog speed selection. Let's increase the jog speed upward. Press enter to select the speed and to re-enter the jog operation mode. Again the arrow keys now allow jogging of the motor. Press mode to exit the jog operation. When you have finished jogging the motor you should cycle control power to the drive. This will reset P2-30 re enabling the Servo enable, the clockwise limit, and the counter clockwise limit inputs. The other changes we've made such as the motor type and the jog speed will be retained.

IGBT of Fuji Motor Electronic Equipment Technology
The IGBT technology of Fuji motor and electronic equipment technology has been commercialized since 1988 and has been supplied in the market so far. Figure 1-3 shows the development process and application technology of IGBT products from the first generation to the fifth generation. Epitaxial wafers are used in the first to third generation IGBT, and the characteristics are improved by optimizing life cycle control and refinement technology of IGBT. Then, the fourth and fifth generation products have achieved significant characteristic improvement through the transition from epitaxial wafer to FZ (floating zone) wafer. In this regard, the design policy of IGBT has changed greatly compared with the past.Firstly, the basic design idea of IGBT using epitaxial wafer (series products up to 600V of the third to fourth generation, called "breakdown type") is as follows. In order to realize the low-pass state voltage during IGBT conduction, a large number of carriers are injected from the collector side to fill the IGBT with high concentration carriers. In addition, the n-buffer layer specially set to maintain the high voltage forms a very thin n-layer, so as to realize the low-pass state voltage. In order to realize fast exchange, life cycle control technology aiming at the rapid disappearance of carriers filled in IGBT is also adopted (through these, low exchange loss (eoff) can also be realized). However, once the life cycle control technology is applied, even in the normal on state, due to the effect of this technology (the carrier transport efficiency decreases), there is a problem of increasing the on state voltage, which can be solved by further high carrier injection.In short, the basic design concept of IGBT using epitaxial wafer technology can be simply summarized as "high injection and low transmission efficiency". In contrast, IGBTs using FZ wafers (series after the fourth generation 1200V) adopt a reverse basic design to inhibit the injection of carriers from the collector side and improve the transmission efficiency by reducing the injection efficiency. In the above-mentioned design concept of IGBT using epitaxial wafer "high injection and low transmission efficiency", the carriers that are not easy to be injected are forcibly suppressed through the control of life cycle, which not only limits the improvement of characteristics, but also increases the standard deviation of on-state voltage characteristics through the control of life cycle, It is very disadvantageous to the large capacity required for parallel use with increasing requirements in recent years. The technology developed to overcome this problem is a new IGBT using FZ chip (NPT: non punch through (used from the fourth generation IGBT) / FS: field stop (used from the fifth generation IGBT) - IGBT). The IGBT does not adopt life cycle control. Its basic design idea is to control the impurity concentration of the collector (P layer), so as to inhibit the carrier injection efficiency. However, in order to realize the characteristics superior to the IGBT using epitaxial wafer, it is also required to realize more than one hundred for the 1200V high voltage resistant series IGBT μ M (the thickness of n-layer in NPT and fs-igbt using FZ wafer ≈ the thickness of chip (wafer). The thinner the thickness, the lower the on state voltage can be generated). In short, it is not too much to call the development of IGBT using FZ chip a challenge to chip thickness.Fuji electric and electronic equipment technology has solved these problems. Starting from the fourth generation 1200V series - IGBT, it has realized the commercialization of "s series" constructed by FZ chip NPT. In addition, 600V series technology with higher thickness requirements is further developed, and 600v-u2 series (fifth generation) is being commercialized. In addition, in 1200V series - the fifth generation "U Series", in order to improve the performance better than s series, NPT structure has been changed to FS structure.The so-called FS structure does not use the life cycle control technology. While following the basic design concept of "low injection and high transport efficiency" of carriers, an n buffer layer to maintain voltage is set on the FZ wafer, so as to realize the IGBT structure thinner than the NPT structure. Through this change, 1200v-u series realizes the low on state voltage characteristic better than s series, and completes its commercialization. In addition, this technology is also used in 1700V series high voltage withstand series, and is also starting to be commercialized.Figure 1-3 changes of Fuji motor electronic equipment IGBT application technologyIn addition, Fuji electric and electronic equipment technology is also refining the surface structure indispensable for the improvement of IGBT characteristics (IGBT is formed by multiple IGBT plates. Through refinement, the more plates, the more low on-state voltage can be realized). Up to the fourth generation products, the planar structure (the structure of planar IGBT) has been used to promote refinement, so as to improve the characteristics. However, starting from the fifth generation products - 1200 and 1700V series, the grooved IGBT technology slotted on the Si surface and constituting IGBT has broken the subtle technical barrier and achieved unprecedented characteristic improvement. Figure 1-4 shows the change of characteristic improvement of 1200V series.Figure 1-4 improvement of balance characteristics
