Experts pretty much agree that motor torque is proportional to motor current and motor speed is proportional to drive supply voltage, but do you know when this might not be true? This paper reviews the performance of constant current stepper drive across the motor speed range and the impact of the motor’s inductance, back-EMF and supply voltage on both low speed and high speed operation.
