| 摘要 |
The electronically commutated electromagnetic apparatus (ECA) of the present invention is a direct current (DC) rotating electro-magnetic machine that converts electrical energy into mechanical energy when operating as a motor and mechanical into electrically energy as a generator. The ECA has a slot to slot commutation combined with a unique prime numbered concentric winding layout which mitigates alternating current (AC) losses at extremely high speeds and torque ripple at extremely low speeds. Applications include compact low cost, high speed centrifugal compressors and very low speed direct drive wind turbines. |
