sir, wat is the formula for stepper motor power calculation. my stepper motor is rated voltage is 2.7 volts. and current rating is 6.0A, and holding torque is 8.7Nm. and 4 pin operation.

 

Well, it's a two-phase stepper motor, 2.7 volts and 3 amps per winding, unless it is rated with 6A per phase. Is it? Power dissipation is V*A.
