Small Motor Variable Speed Control System Integration Technology

The unprecedented growth in motor drives over the past decade resulted from the process improvements demanded by the automation industry and white goods like air conditioning, Ventilation, washing machines, freezers. In these equipments, the motor driver should provide high performance, small size, and low cost. It is a good solution to integrate the motor driver system. The techniques of integrate the motor driver system is the combination of power electronic techniques with micro-electronics techniques (integrate the motor driver system by power integrated circuit techniques or by packaging techniques). With the technique, the new production provide advanced performance, smaller size, and reduced costIn this paper, the present status of motor control techniques, the present status of micro-electronics techniques, and the present status of integrated circuit techniques are reviewed. Present some samples of AC motor driver (DSP motor controllers, microprocessor controllers, motor control 1C controllers). Compare the performances of these AC motor drivers with each other. Then some conclusions are gotten. With these conclusions, we design a motor control integrated circuit, and examine it by the soft of ASIC design. The motor control integrated circuit can provide improved performance.
