Other Parts Discussed in Thread: CSD88584Q5DC
I used the drv8306 in a portable device.
12V DC power supply for motor.
- 50W power output
- following is my circuit.
- 8000rpm ~ 30000rpm speed control
- 15K PWM
- mcu:STM32BOG1RCT6
The problem is temperature is up to nearly 120 Degree Celsius without load.
I checked the orders of the phase and hall has no problem.
I driving the motor with another motor driver under the same condition, the temperature was only 70 Degree Celsius.
I don't know why the temperature of the motor is so high, could someone can give me some advices for this?
Thanks,
Best Regards,
Matt
