Struggling to find the appropriate drive for my BLDC motor application

Using Arduino Motors, Mechanics, Power and CNC

Hello everyone,

in my project i have to control a Brushless DC motor with these specifics:

  • Power: 780W
  • Nominal Torque: 3.6Nm
  • Rotation Speed: 2050rpm
  • Nominal Current: 37A

As you can see it's a big motor and I want to control it with Arduino through PWM but I wasn't able to find a suitable drive for my application.

Hopefully you guys can point me in the right direction.

Thanks in advance for your time!

Cheers

Have you considered using a controller from the radio controller hobby?
There are plenty that can handle those power requirements, and they are reasonable affordable.
You would use the servo library to communicate to the controller, called an ESC in the hobby.

Voltage? Does it have built in commutation sensors or is it sensorless? How many wires?

The right direction is to post full details of the hardware, not edited highlights - provide the datasheet or
product page web links please. Otherwise we'll just be interrogating you for lots of details pointlessly.

And explain your application - we have no idea at all what you want to achieve with this motor unless you tell us...
