My Holidays: Scott Miller, CEO of Volunteering NZ

Scott Miller, CEO of Volunteering NZ, is a judge in the NZ Charities Technology Awards on Thursday in Auckland. What was your greatest holiday? The three months I had living in the Peruvian Andes, climbing the high peaks of the Cordillera Blanca. It was an extraordinary time climbing 6000m peaks with little oxygen, eating cuy (guinea-pig), and bartering on the value of a pack of donkeys to share the load to base camp. And the worst? Cuba. With my wife and young son, we travelled Cuba like the locals, and were constantly conscious of the plight of this small island nation caught between economic ideologies, technological displacement and infrastructure decay. The people however, were truly amazing, and we could not have had more generous hosts or interactions during our stay. If we bump into you on holiday, what are you most likely to be doing? I am likely to be hunting down the corner cafe that is popular, not because Lonely Planet or TripAdvisor recommend it, but because the locals know it's the best. If we could teleport you to one place in New Zealand for a week-long holiday, where would it be? It would have to be Akaroa. The nostalgia of family holidays, young love, coastal aromas of low tide, fish and chips on the pier and the stunning topography. Pure bliss. How about for a dream holiday internationally? I would love to take my wife and son on a cycle-tour through Eastern Europe. Cycle-touring is the best way of eating as much delicious food as you like without ever feeling guilty about it. What's the dumbest thing you've ever done when travelling? One time in Peru I was invited to share some cervezas with some "friendly" locals. Unfortunately they never had any change, so I would naively go and buy the rounds, and they would pay me back in $50 notes. Upon trying to spend some of these notes at another store, I found I had been conned several hundred dollars. Aisle seat or window seat? Can I say window for take off and landing and aisle for the duration of cattle class? Complete this sentence: I can't travel without ...A good pair of walking shoes. The ability to get off the beaten track and explore the streets and suburbs only the locals walk is the best way to understand the cadence of their environment. What's the best travel tip you've ever been given? Wake and sleep local time, regardless of the landing time. What was the most memorable meal you've had while travelling? In Singapore I was given the full VIP experience that included pistachios at Raffles before fine-dining some 150m above ground. What's the best thing you've brought back from a trip? A ceramic trout. Favourite airport to land at? Wellington, because it means I have made it home in one piece. What's the next trip you've got planned? I head back to Dayton, Ohio this Sunday for another work trip. Dayton was unfortunately featured in Time magazine as a centre of the opioid epidemic gripping the US. However it was once the pride of the nation as the home of many inventors including the Wright Brothers (first flight), Charles Kettering (the car starter motor) and Edward Deeds (National Cash Register).

Is This Bad Starter Motor?
Sounds more like a connection problem or bad battery. Even if the starter was bad and the connections and battery were in good shape the voltage would not drop below 8 volts. Check for poor connection at the battery (both the positive and negative cables) The battery when charged up should show a static charge of 12.7 volts Hope this helps1. how does an induction motor work?The simplest of all electric motors is the squirrel-cage type of induction motor used with a three-phase supply. The armature of the squirrel-cage motor consists of three fixed coils similar to the armature of the synchronous motor. The rotating member consists of a core in which are imbedded a series of heavy conductors arranged in a circle around the shaft and parallel to it. With the core removed, the rotor conductors resemble in form the cylindrical cages once used to exercise pet squirrels. The three-phase current flowing in the stationary armature windings generates a rotating magnetic field, and this field induces a current in the conductors of the cage. The magnetic reaction between the rotating field and the current-carrying conductors of the rotor makes the rotor turn. If the rotor is revolving at exactly the same speed as the magnetic field, no currents will be induced in it, and hence the rotor should not turn at a synchronous speed. In operation the speeds of rotation of the rotor and the field differ by about 2 to 5 percent. This speed difference is known as slip. Motors with squirrel-cage rotors can be used on single-phase alternating current by means of various arrangements of inductance and capacitance that alter the characteristics of the single-phase voltage and make it resemble a two-phase voltage. Such motors are called split-phase motors or condenser motors (or capacitor motors), depending on the arrangement used. Single-phase squirrel-cage motors do not have a large starting torque, and for applications where such torque is required, repulsion-induction motors are used. A repulsion-induction motor may be of the split-phase or condenser type, but has a manual or automatic switch that allows current to flow between brushes on the commutator when the motor is starting, and short-circuits all commutator segments after the motor reaches a critical speed. Repulsion-induction motors are so named because their starting torque depends on the repulsion between the rotor and the stator, and their torque while running depends on induction. Series-wound motors with commutators, which will operate on direct or alternating current, are called universal motors. They are usually made only in small sizes and are commonly used in household appliances.2. is it bad to have a car with a lot of miles but new motor?well you got the tranny. that can go at any time. but if it is good then you will only have the odds and ends3. How does an AC motor work?Basically, an AC motor is a type of motor that is operated by an alternating current. It has two basic parts. First is a stationary stator and another is rotor.The above diagram shows the configuration of stator winding. I am giving an example for 3 phase motor. Hence, in above diagram A, B and C are the three phases. When the current is supplied to the windings, all the three windings become electromagnets. When the current reverses polarity of the winding also reverses.The stator windings are 120 degrees apart. Now, when the supply is given to the windings, only 2 phases of the supply are active and the remaining one phase is non-active or has no current flowing through it. Hence, the one phase which has no current flowing through it will have no magnetic field.Let us assume that at the start phase A has no current and no magnetic field produced. Phase B has current in negative direction and phase C has current in positive direction. Now, at some time 1, phase A has current in positive direction and phase B has in negative direction. While phase C has no current and no magnetic field. The resultant magnetic field vector has rotated 60 in the clockwise direction. Now at some time 2, phase A has current in positive direction and phase C has in negative direction while phase B has no current and magnetic field. The resultant magnetic field vector has rotated another 60.Now, after the end of 6 such cycles, the resultant magnetic filed vector would have rotated 360 or one full rotation. This is known as the Rotating Magnetic Field.Now, According to Faraday's law of induction,An emf induced in any circuit is due to the rate of change of magnetic flux linkage through the circuit.As the rotor winding in an induction motor or AC motor are either closed through an external resistance or directly shorted by end ring, and cut the stator rotating magnetic field, an emf is induced in the rotor copper bar and due to this emf a current flows through the rotor conductor. Here the relative speed between the rotating flux and static rotor conductor is the cause of current generation.As per Lenz's law,The rotor will rotate in the same direction to reduce the cause i.e. the relative velocity.The rotor speed should not reach the synchronous speed produced by the stator. If the speeds equals, there would be no such relative speed, so no emf induced in the rotor, and no current would be flowing, and therefore no torque would be generated. Consequently the rotor can not reach the synchronous speed. The difference between the stator (synchronous speed) and rotor speeds is called the slip. The rotation of the magnetic field in an induction motor has the advantage that no electrical connections need to be made to the rotor.where Ns is the Synchronous speed and Nr is the Rotor speed.THANK YOU FOR READING.Ashutosh Sharma ( )How does an AC motor work?.
