【CW32】Integrated FOC driver based on CW32F030K8U7

Overview

Preliminary hardware debugging completed

I only have a little time to work on social animals every day. The peripherals have been basically debugged, but the FOC has not been completed. The open-loop forced towing is running.

We will continue to promote this project in the future, so stay tuned

After complete adjustment, migrate to CW32

1. Log

(June 22, 2022) SVPWM is turned on, and there is still a problem with one phase of current sampling.

2. Schematic diagram

1. Power input

Larger and larger capacity 1206 package MLCC is used for filtering and energy storage

2. Inverter circuit and current sampling circuit

3. LDO buck circuit

System power supply

4. Buck step-down circuit

Maximum 40V input

5. boost circuit

Powers the gate driver and adjusts the fb resistor to adapt to more types of MOSFETs

6. System indicator light

Contains a power indicator light and a user-programmable indicator light

7. Voltage follower

Provides stable op amp bias voltage

8. RS485 transceiver

Interface for communicating with the controller

9. MCU minimum system

Active crystal oscillators are more reliable

10. Bus voltage sampling

11. MOSFET temperature sampling

Software prevents MOSFET from overheating

12. NOR FALSH

used to store parameters

13. Magnetic encoder chip

Get the mechanical angle of the motor rotor

14. Serial port

for debugging

15. SWD interface

for debugging

FOC didn't get it done, so they forced it to open a loop.
