Shaded pole motors are characterized by which torque property?

Shaded-pole motors are defined by their very weak starting capability. The shading coil on part of each pole creates a delayed secondary magnetic field that produces a weak rotating field. That rotating field is not strong enough to develop significant torque at the instant the motor starts, so the starting torque is very low. Once the rotor picks up speed, the torque remains modest, but the crucial point is that the motor cannot provide much torque to start under load. Hence, the description that matches this behavior is that it has little starting torque.
