Because the 18 Volts is the number only if the motor is being used as a motor This motor is not being used as a motor It is being used as a generator and it is not 100 efficient as a generator It is roughly 8085 efficient as a generator Therefore 18 Volts x 08 144 Volts We know how many Volts our motor will produce at 450 rpm 14

A threephase motor must be wired based on the diagram on the faceplate The first step is to figure out the voltage of your phases In the United States for low voltage motors below 600v you can expect either 230v or 460v That being said there is a wide range of different motors and what you have on hand can be completely different Make sure that the voltage you will be supplying to your motor matches

Starting methods of three phase induction motors An induction motor is similar to a polyphase transformer whose secondary is short circuited Thus at normal supply voltage like in transformers the initial current taken by the primary is very large for a short while Unlike in DC motors large current at starting is due to the absence of back emf
