As with generators, the field winding of motors can be arranged in shunt is called shunt motor. In a shunt-connected motor, the field is connected directly across the voltage source, and is therefore independent of variations in load and armature current. So the torque developed varies directly with the armature current. In a shunt motor, the variation of speed from no load to normal, or full load is usually only about 10% of the no-load speed. For this reason, shunt motors are considered relatively constant-speed motors. When a shunt motor is started, the starting current is low because of the added starting resistance, so the starting torque will also be low. Shunt motors are normally used when constant speed under varying load is desired and when it is possible for the motor to start under light or no-load conditions.
