摘　　要：对于微型BLDCM在负载较大和低速运行的场合,采用传统无位置传感器控制技术出现启动反转和启动困难的情况,首先根据安培环路定理分析相电感与转子位置的关系。通过施加一定顺序的电压矢量,设计了一套根据其电流响应来判断转子位置的方法;然后使用Matlab/Simulink搭建控制系统模型,并进行仿真。实验结果表明:采用此方法,微型BLDCM可以在较大负载的情况下从任意位置无反转启动,并且可以低速运行。For situations with large load and low speed operation, the traditional sensorless control technology of micro-Brushless Direct Current Motor(BLDCM) has the problems of starting reversal and difficult starting. First, the relationship between phase inductance and rotor position is analyzed based on Ampere circuital theorem. A method was designed to determine the rotor position by injecting a certain sequence of voltage vectors according to its current response. The control system model was built by using Matlab/Simulink. The experimental results show that micro-BLDCM can start from any position without inversion under heavy load and can running at low speed.
