What is mean by plugging in three phase induction motor?
Plugging in three-phase induction motor means interchanging of any two phases of a stator for quick stopping.
The slip of 400 V, three phase, 4 -pole induction motor when rotating at 1440 rpm is
The slip of 400 V, three phase, 4 -pole induction motor when rotating at 1440 rpm is 4 percent
How is a three phase cage induction motor self starting?
Any type of induction motor is self starting. Because the reason for torqe production require two flux displaced by some angle theta.If theta is constant with time then torqe will be constant;if ... torqe also pulsating. In induction motor this angle theta is not pulsating.so it is self starting
Explain with neat circuit diagrams the procedures to perform no load and blocked rotor tests on three phase induction motor.
Explain the need and steps to conduct the reduced voltage running up test on the three phase induction motor.
State any four advantages of three phase induction motor.

how can we reverse the direction of rotation of three phase induction motor ?
The direction of rotation of three phase induction motor can be reversed by plugging i.e by changing any two out of three phases of the supply to the stator of the Induction motor terminal.
speed control methods of three phase induction motor?

Split phase induction motor
Split phase induction motor : There are two windings used in split phase induction motor. It is a type of single-phase induction motor. There are two winding one is called main winding and ... motor have low starting torque it is used for small fans, blowers, centrifugal pumps, grinders etc.
Reason is kinetic energy
If a single phase induction motor runs slower than normal, the most likely defect is worn bearings.
