Which type of motor has a relatively small starting torque?

The correct answer is option 1):(Resistance start induction motor)

Concept:

• Induction motor torque at starting, is inversely proportional to the addition of rotor resistance  and its standstill rotor reactance
• So resistance start motor have lowest starting torque

Additional InformationUniversal motor: High speed, high starting torque, operate on either AC or DC power

Capacitor start motor: High starting torque, low power factor Capacitor run motor: Low starting torque, high power factor
