Brushless DC motor driving integrated system and driving method

Abstract

An integrated brushless DC motor drive system, used to drive multiple brushless DC motors, including: ADC, used to collect BLDC current value data in the brushless DC motor; ARM chip, used to convert the brushless DC motor in the FPGA chip After the Hall code disk data of the DC motor is read by the bus, the motor control value is calculated according to the Hall code disk data of the brushless DC motor, and the motor control value is sent back to the FPGA chip through the bus; and the FPGA chip is used to receive The motor control value sent by the ARM chip and the Hall code disc data used to store the brushless DC motor, and the FPGA chip has multiple NMOS; where the FPGA chip controls the corresponding multiple NMOS to open or close according to the motor control value , to issue a BLDC current value, whereby the brushless DC motor is driven time-synchronously.

Description

technical field [0001] 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 [0002] 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 sampling resistor to detect the running speed, and directly send the detected value back to the MCU, so that the MCU can send the next control signal to adjust the motor control signal in real time. The MCU also has means to judge whether to shut down the motor. By ...
