| Abstract |
The self commutated synchronous motors, switched reluctance or brushless DC, are more and more often used in a wide range of power, from stepping to traction motors. In a self-commutation mode, the motor is supplied by an electronic power driver, the control of which is based on the rotor position information. One of the main problem of the self-commutation is the motor coils excitation at the correct position to develop the required torque with the best efficiency. In this purpose a direct or indirect rotor position detection and the commutation lead angle regulation are necessary. In this paper, a new torque optimisation strategy, using an indirect lead angle regulation is presented. |
