How do you increase the starting torque of a three phase induction motor?

Starting torque of an induction motor can be improved by using following methods.

  1. Increasing Internal Rotor Resistance.
  2. Increasing External Rotor Resistance.
  3. Variable Voltage/Frequency.

What is the condition for maximum starting torque?

It can be proved that starting torque will be maximum when rotor resistance/phase is equal to standstill rotor reactance/phase. Under the condition of maximum starting torque, Φ2 = 45° and rotor power factor is 0.707 lagging [See Fig.

What are the factors that determine the torque of a DC motor?

Speed Variation

Output torque of a DC motor is proportional to the product of the main pole flux, armature current, and a machine constant that is a function of armature windings. Therefore, with armature voltage speed control and constant shunt field excitation, the torque is dependent upon the armature current only.

How do you create torque?

Increased displacement is the easiest way to achieve increased torque. Very large cylinders and a long stroke offer the greatest cylinder volume and overall piston area for the fuel charge to push against the crankshaft or lever, if you will.
