Hello. Unfortunately not. It’s better to use a proper 3-phase motor driver IC.

In reply to Pranav K. Hello. Braking was not provided for in that project. You can modify the schematic to remove the protection.

Is there any way i can use this driver to control a 2.6 kw brushless dc motor. Do i need to do any modifications? Is it okay if i boost the ir2110 output using external push-pull amplifier to get enough gate current?

P.S The motor is 64V 2.6kw. We are making a electric vehicle for our engineering project.
Thank you

Hey, How are you braking the motors? How are you created path for current created by the motor coils ?. I don’t see any logic to close both upper/lower mosfets together ? .Thanks !

In reply to Oleg Kutkov. hi oleg. can you please tell me what kind of mode you are driving this motor? i mean : is it locked anti phase or sign magnitude or drive/ coast mode ? \

In reply to Adrian. Hello Adrian,

IC 74HC00N to protect against false triggers is not necessary?

Yes, that's correct.

C16 and C17 Those caps are optional, but you can use 100nF high-voltage ceramic

Hello Oleg, first of all I am grateful for sharing your circuit, I am going to try to replicate it, and I would like to ask you I am going to use a TL494 in push pull mode as a pwm generator. I understand from this that IC 74HC00N to protect against false triggers is not necessary ?
Another question C16 and C17, what values does it have since it does not show it in your diagram?
Thank you very much, I await your kind reply

to retrofit a late machine i need a driver for the spindle motor DC 15kw 250V 75A
i’m not an electronic expert is it possible to diy ? would be nice if i can controle it with puls direction
or where can i find such a driver ready for use

In reply to Ben Pauza.

Sure. It’s all about traces and connectors. You can use the variant with big external FETs like in my photo.
Also, you can reinforce PCB traces with additional wires soldered over. I can recommend drilling extra holes to reinforce VIAs.
It would be great to replace connectors with something much more robust.
Then it should be good.

In reply to Oleg Kutkov. Is the limiting factor the trace size? If I make them wider and thicker copper, could this be scaled to 50 or 100 amps with the right NFETS?
