Abstract
In a servo control system for a reluctance motor, the output of a reference waveform generator is applied to a power converter through a current controller. Under standstill conditions, at least two of the motor windings are energised so that both forward and reverse torques are established, the forward torque being in equilibrium with the reverse torque. The controller may be responsive to a bias signal to establish said torques. The control system may form part of a reluctance motor drive system.
