current - Starting torque of series vs shunt DC motors

WebThese have very low starting torque as a result. Permanent split capacitor (PSC) motors use a capacitor in one of the windings to increase the current lag between the two windings to make the rotor turn. Often one winding is called the start winding and a run winding. WebStarting torque is very small (about 40-80% of full-load torque). The efficiency is quite low (20 to 50%). Power factor is also very poor ranging from 0.5 to 0.6. It has little overload capacity. Speed falls with the decrease in applied voltage.

Parallel or shunt DC motors provide lower starting torque but have a flatter speed vs. load relationship and can, therefore, provide a constant speed almost independent of the load applied.

WebThe large rotor reactance at the start makes the starting torque of the motor poor. The motor draws about 5 to 6 times the current of its full load current and produces very less torque. Most of the current is reactive in nature and does not … Web1 dec. 2024 · As R2 is neglected, starting torque now depends upon X20 which is maximum at starting as slip is 1. So starting torque is low in induction motors. To get maximum starting torque, resistance is added to the rotor while starting slip ring motors, which is reduced gradually as motor picks up the speed.
