Abstract
Electrical energy conversion device as applied to various areas of the national economy. Generally be divided into motor AC motor and DC motor. Compared to AC motors, DC motor starter has a good performance and a broad smooth speed control characteristics, have been widely used in electric locomotives, trolley buses, rolling mill, machine tools and equipment need to start and start-up speed of occasions. However, for the DC motor commutator and brush is to rely on exchange flow, in the functioning of the process of frequent, as the commutator and brush friction, on the one hand, consumption of brush, so that we may not be from time to time inspection and replacement of electric Brush, time-consuming and labor-intensive; On the other hand, have a spark, electromagnetic interference, the impact of nearby electrical equipment. Permanent magnet brushless DC motor is developed in recent years a new type of motor, with its use of electronic technology for brush DC motor instead of the mechanical-electrical integration for the product. It has the general operation of DC motor high efficiency, large starting torque, speed and mechanical properties of a wide range of advantages for the linear and the AC motor with simple structure, reliable operation and convenient maintenance. This topic aims to research permanent magnet brushless DC motor controller, which takes the ASIC BLDCM MC33035 as the core. It designs the main circuit of permanent magnet brushless DC motor controller, mainly including the rectifier and the inverter.
