ABSTRACT:
An electric motor controller is disclosed that controls the torque of a switched reluctance motor with an angle controller that eliminates the need for a look-up table. In one example, the electric motor controller includes an angle controller that employs edge-triggered monostables to generate a single pulse firing signal which is synchronized with rotor position and whose pulse length varies with torque demand. An angle firing circuit utilizing freewheeling is also disclosed.
