| Abstract |
High-performance electric drive with possible applications to machine tools and robots is described. It integrates a synchronous permanent magnets motor, supplied by controlled current-source inverter and a control system with rotor position, speed and current feedbacks. The control system realises control laws which provide wide frequency band, commutation stability, maximum driving torque and minimum speed pulsations. All these features are achieved by means of proper regulation of the shift of the inverter's switching angle oi at high speeds, and PWM of motor currents at low speeds. The PWM strategies of the controlled-current brushless d.c. motors differ from those of asynchronous motors. They are also influenced by the construction of the motor. These problems, as well as ways for their solution and experimental results are considered in the paper. |
