Commutator for switched reluctance drive

摘要: A commutator for a microcomputer based switched reluctance drive employs selectively addressable non-volatile memory, e.g. ROM, to store stator phase firing patterns and facilities selective adjustment of turn-on angle pulsewidth switching current pulses. Firing differing only in their respective pulses can be stored different sections the memory or same section where word bit width permits. The pulse position duration allows torque control motor over very wide speed range.
