Breakdown Torque - an overview | ScienceDirect Topics

From Fig. 7.14, a high rotor resistance will provide a high starting torque, leading to rapid acceleration of the mechanical system.This is desirable because short acceleration times reduce the stress on the power system caused by high starting currents. While high starting torques are desirable, high rotor resistance results in a relatively high slip during normal running operation.

Wound Rotor Motor: What is it? - Motion Control Tips

However, wound rotor motors are beneficial in applications with high inertial loads – such as large fans, pumps, and grinding mills – because the wound rotor design allows the load to be accelerated gradually through speed and torque control. And they can develop very high starting torque at standstill with low inrush current.

What are wound field motors and where are they applied?

With low starting torque and constant speed, shunt wound DC motors are used in applications where good speed regulation is needed with varying loads, such as grinding machines and lathes. Another common use for shunt wound motors are processes that require constant tension, such as printing and winding.
