Hello,
May i know where can i find the information for operation and speed control of induction motors like a 3-phase squirrel-cage induction motor, determine the performance characteristics of an induction motor under load condition and no-load condition.
I have got some questions too.May i know where to get those help?
Pls advise.
(1) The caculated no-load input current and power of the motor as a percentage of their full-load(rated) values are considerably hiher than those of a transformer.Why is this so?
(2) Estimate the starting current of the motor(as percentage of its rated value) when it is started at rated voltage. How can the starting current be reduced to an acceptable value in practice?
(3) What's the relationship between the no-load speed and frequency?
Pls advise.
Thanks.
