| Abstract: | In this paper, the microcomputer control system of a brushless DC motor without a rotor position sensor is described in detail. The permanent magnet rotor position is determined by sensing terminal voltage of three phase stator windings, and the motor operates as a separately controlled synchronous motor when starting. This brushless DC motor can work in three patterns open loop control, speed negative feedback control, and voltage negative feedback with current positive feedack control. |
