Abstract
Brushless DC Motor (Brushless DC Motor, referred to as BLDcM) control system is a new type of speed control system, has a good running and economic performance, simply controlled. Brushless DC motor commutation alternative is the use of electronic and mechanical brush commutation, not only has good speed regulation performance of DC motors, AC motors also has a simple structure, reliable operation, easy maintenance and so, in many fields have been widely application.
The rapid development of modern control theory, brushless DC motor set all relevant scientific and technological development results in one, so there is a clear technological advantage. Recent years, with the rapid development of power electronics and power electronic components substantially lower prices, and the extensive use of ASIC, brushless DC motor circuit simplified a lot, cost reduction, the price drop. Brushless DC motor drive and control technology as a branch of electrical transmission in the field, also showed their specific areas of great vitality. Motorola's MC33035 is a second generation of brushless DC motor controller ASIC. Based on this chip, brushless DC motor controller design required a simple external circuit, high reliability and good stability.
This paper introduces Motorola's 2nd generation brushless DC motor controller chip MC33035 dedicated the basic principles of design of a dedicated control chip as the core components of the MC33035 Brushless DC Motor Controller.
