Then, induced currents are generated in the rotor bars. The induced currents tend to oppose the ﬂux variation in the rotor coils resulting in a mechanical torque applied on the rotor. Then, the rotor starts turning at a speed ωm and the rotor currents oscillating at the pulsation ωr = ωs − pωm . The electromagnetic torque is proportional to the pulsation ωr . It vanishes whenever the rotor current pulsation is zero. This is called synchronization. In normal operation, torque generation is necessarily accompanied by a difference ωr between the stator pulsation ωs and the rotor speed pωm .
This provides the motor with robustness but makes its control more complex. The wound rotor induction motor is similar to the squirrel-cage motor except that the rotor winding is made of individually insulated coils. Connections from the coils are brought to collector rings. The rotor circuit is not short-circuited on itself as in the squirrel-cage motor. 2). 1 Squirrel-cage induction motor.

The rotation speed of the turning ﬁeld is proportional to both the number of poles of the machine and the pulsation of the stator currents (Krause et al. 2002; Multon et al. 2005). 2). In the ﬁrst case, the rotor consists of poles and windings wounded around. The windings carrying a DC current produce a magnetomotive force (MMF) along the air gap (Kothari and Nagrath 2004). In the second case, the MMF is generated by the permanent magnets. The inductor magnetic ﬁeld interacts with the turning ﬁeld created by the stator.
