Electrical Motors Starting Resistor

Motor speed controlling is one of the main and typical applications of industrial resistors. These resistors are used to control of torque and speed characteristics of both AC and DC motors. Limitation of inrush current is the other application of starting resistors.

Starting circuit of rotor wound induction motors

In the rotor wound induction motors, the rotor windings are connected to the slip rings. The slip rings through inside brushes transmit the electrical power to the starting circuit. With regard to the change of resistances value, the current of rotor is decreased. As a result, both speed and starting torque of motor are controlled. Usually, to calculate of resistances, the following parameters are utilized:

Application
Rated power
Rated rotor voltage (secondary voltage)
Rated rotor current (secondary current)
NEMA class of motor
Step numbers
