Stepper motors
with permanent magnet rotor inside and 2 or 4 stator windings. The winding can be bipolar (2 phase) or unipolar (4 phases). We offer suitable drivers for constant voltage or constant current mode.
Special features: high holding torque and detent torque. We can combine stepper motors with gearboxes in order to increase resolution and torque. Mounting clips are typically available on stock.
