Detail Analyses of 3-step Start for SLBLDC Motor |
| |
Abstract: | A 3-step start technique is usually applied to a position-sensorless brushless DC (SLBLDC) motor with back EMF method.This paper analyzes the conditions to prevent the motor from losing-step during the accelerating step and the state-changing step.Simulation and experimental results are also presented to verify the analyses. |
