Speed Regulation of DC Motor - Electrical4U
网页2012年2月24日 · Speed Regulation Definition: Speed regulation of a DC motor is the change in speed from no load to full load, expressed as a fraction or percentage of full load speed. Good Speed Regulation: A motor with good speed regulation has a minimal difference between no-load and full-load speed.
