摘　　要：反电势法无位置传感器无刷直流电机常常采用三段式起动技术。本文分析其加速和切换过程中确保电机不失步的各自条件，并用仿真与实验手段加以验证。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.
