DESIGN OF THE CONTROL CIRCUIT OF BLUSHLESS DC MOTOR DRIVER

摘要

The present invention relates to a control circuit design of a BLDC motor drive device, and more particularly, a BLDC using a logic gate (CPLD) that can implement a low-cost design and stable control operation, and easily modifies the control implementation details. The control circuit design of the motor drive device. This control circuit design analyzes the Hall sensor input, and only the normal signal controls the output terminal of the motor-drive unit, and the logic gate array IC in which the drive unit input is controlled by PWM control signals by various gate configurations arbitrarily determined by the user. CPLD) circuit. As a result, by implementing a design that can quickly and easily respond to various functional requirements of the market at a low price, it is possible to widen the application range of the BLDC motor drive device and gain many advantages in the market competitiveness. It is effective in utilization.;BLDC motor, control circuit, logic gate, logic gate,
