Stepper Motor Theory Of Operation
The detent torque can be noticed by turning a stepper motor by hand and is generally about one-tenth of the holding torque. Stepper motors are rated in terms of the number of steps per second, the stepping angle, and load capacity in ounce-inches and the pound-inches of torque that the motor can … Document Viewer
