The powerful stepper motors are mainly used for holding or positioning applications, as for example plotters, printers, moving lights or mirror mounts etc. A stepper motor (or step motor) divides a full rotation into a number of discrete steps.
The motor's position can then be commanded to move and hold at one of these steps. Once stopped, the stepper holds the load steady with a holding torque.
This is a NEMA 14 stepper motor. The NEMA 14 is smaller and generally lighter than for example a NEMA 17, however, its size is not an indication of its power.
1. Inexpensive, as the rotor contains no winding slip rings or commutator.
2. Easy to position moves in steps based on pulses supplied to the stator windings.
3. Direction of rotation is changed by reversing the pulse sequence.
4. Speed control through frequency of pulses or pulse rate Applications: Computer-controlled stepper motors are mainly used for holding or positioning applications, as for example plotters, printers, moving lights or mirror mounts.
