The speed regulation of a synchronous motor is
Right Answer is:
0%
SOLUTION
The speed regulation of a motor expresses how much its speed varies between no-load and full load. The synchronous motor runs at a constant speed whose magnitude is dependent on supply frequency and the number of poles.
The steady-state speed of the motor is constant from no load to the maximum torque that the motor can supply (called pull-out torque).
where
nnl = no-load speed
nfl = full load speed
Since the speed of the motor is constant hence its speed regulation is zero.
