Field Demonstration of Three-Phase Wanlass Motors

摘要

Electric motors are major part of the load at Naval shore facilities. The Naval Civil Engineering Laboratory (NCEL) investigated the Wanlass motor as a means of reducing power consumption, reducing current flow, and improving power factor, as compared to standard motors. NCEL surveyed the literature on single-phase and poly-phase Wanlass motors and tested poly-phase Wanlass motors. Efficiency, current, power factor, load sharing, temperature rise, vibration and noise, torque-speed, and reliability were judged. A reduction in current flow and a corresponding improvement in power factor can be expected with the Wanlass rewind. A small improvement in efficiency - a reduction in power consumption - is possible but not certain. It was recommanded that Wanlass rewinds not be purchased on the basis of energy savings or power factor improvement. (Author)
