I drive a BLDC motor with an ESC. When using power from a LiPo battery everything works as expected. When I use a power supply, on rapid stops or slowdowns motor generates voltage spikes, which send my ESC to overvoltage protection.
How can I deal with it? Will a zener diode work with PSU, if it's voltage rating will be higher than PS voltage and power rating enough for heat dissipation?
May be there is another way to do it correctly?
Additional info: With oscilloscope I am unable to catch spikes on power input, no spikes there. They only show up on motor phase lines. I see PWM signal. I can catch higher voltage than usual there when braking or slowing down.
I have 1300 uF capacitance on the ESC. I use T-Motor MN5212 and 18 inch propeller.
Wires from the PSU to ESC are 10 cm.
Tried without the prop, same result.
