Three-phase brushless motor driving board

Abstract

The invention provides a three-phase brushless motor driving board. A substrate is provided with a power module, a human-machine interaction module, a motor driving module, a three-phase voltage acquisition module, a motor control board adaptive interface and a Hall sensor adaptive interface. The power module provides 5V DC voltage for the human-machine interaction module, the three-phase voltageacquisition module, the motor control board adaptive interface and the Hall sensor adaptive interface. The power module provides 15V and 24V DC voltage for the motor driving module. The human-machineinteraction module, through the motor control board adaptive interface, sends a corresponding operation instruction to the motor control board and receives and displays the motor-related data acquiredby the motor control board. The motor driving module receives a PWM signal sent by the motor control board through the motor control board adaptive interface, and inverts the externally input 24V DCvoltage into specific three-phase AC power according to the received PWM signal and outputs the specific three-phase AC power to the motor to drive the motor to work. The three-phase brushless motor driving board is simple and novel in design, can replace the motor control board arbitrarily, and can monitor the test data in real time.

Description

technical field [0001] The invention relates to a three-phase brushless motor driving board. Background technique [0002] At present, there are many control schemes for commercialized three-phase brushless motors. Most of them are designed by motor control board manufacturers to launch a set of corresponding motor drive boards. The motor control board and motor drive board are integrated on the same PCB board. On the Internet, it becomes a development board, and the manufacturer of the motor control board directly provides the development board for users to test and select. Before selecting the motor control scheme, it is necessary to evaluate the control effect of different motor control boards and different motor control schemes. If the development board with integrated motor control board and motor driver board is used for testing, testing multiple schemes requires With multiple independent development boards, the test products cannot be reused in this way, which will i...

Problems solved by technology

If the motor control board and the motor drive board are integrated together, the consistency of the motor drive circuit during the test cannot be guaranteed, which will affect the test conclusion

Moreover, the motor drive boards in the prior art generally communicate with the PC software through serial ports to achieve visualization, lacking an intuitive human-computer interaction interface, and different motor control board manufacturers need to use different PC software. To install different software, the operation is complicated, the versatility is poor, and the software of different manufacturers may be incompatible with each other
