Abstract

The invention provides a brushless DC motor driving method for driving a plurality of brushless DC motors, and the method comprises the following steps of: acquiring BLDC current value data in the brushless DC motors by adopting AD; adopting an ARM chip to read Hall coded disc data of the brushless DC motors in an FPGA chip through a bus, calculating a motor control value through calculation according to the Hall coded disc data of the brushless DC motors, and transmitting the motor control value back to the FPGA chip through the bus; adopting the FPGA chip to receive the motor control value sent by the ARM chip and storing Hall coded disc data of the brushless DC motors, wherein the FPGA chip is provided with a plurality of NMOS; wherein the FPGA chip controls a plurality of corresponding NMOS to be opened or closed according to the motor control value so as to emit a BLDC current value, so that the brushless DC motors are driven in a time synchronization manner.

Description

[0001] This application is a divisional application of the invention patent application with the application number 201910347706.8, the application date is April 28, 2019, and the invention title is "Brushless DC Motor Drive Integrated System and Driving Method". technical field [0002] The present invention provides a drive integration system and method for a brushless DC motor, in particular a drive device and a drive method that can integrate and control multiple brushless DC motors through an FPGA chip. Background technique [0003] Most of the existing BLDC (Brushless DC Motor) drive modules are designed to drive a single BLDC, and an MCU (Micro Control Unit) built with a single ARM chip architecture is used to drive a single BLDC. For example, a prior art discloses a BLDC control system, which uses an MCU formed with an ARM chip architecture to send motor control signals to drive the BLDC. Cooperate with the Hall sensor to detect the motor running direction and the sa...
