ANALYSIS OF 2-LEVEL BIPOLAR CURRENT CONTROL OF 3-PHASE RELUCTANCE MOTORS

The two-level bipolar current controlled three phase reluctance motor drive distinguishes itself from other types by having a single coil/po le/phase (q = 1) three phase uniformly distributed winding. Furthermor e the motor has a distributed-anisotropy rotor with axial laminations for high saliency ratio and a two-level current control triggered by a sample position transducer with six elements per pole pair. The syste m is suitable for small power variable speed drives. The paper present s the theory, digital simulation and tests results pertaining to a lab oratory model.
