摘要：

Generally, a brushless dc motor requires a rotor position sensor for commutation and current control. Resolvers and absolute encoders are used as a position sensor, but they increase cost and size of the motor and restrict the industrial drive applications. Furthermore, as the application field expands, the brushless dc motor is used in a special case where the motor cannot be provided with the position sensor. From these backgrounds, position sensor elimination methods have received wide attention. This paper presents a new control strategy for a brushless dc motor without position and speed sensors. The control is performed by software using DSP-TMS320C25. The prototype has been constructed using a 1.5-kW, 154-V, 2000-r/min, four-pole motor. The test results have been found satisfactory in both steady and transient states.
