20mm PM Stepper Motor

Features
The 20mm PM stepper motor is easily recognizable as it has large outer diameter of 20mm. Often referred as a tin can or can-stack motor, our PM stepper motor is cost-effective electrical device with a typical step angle of 7.5° or 15°.

Currently this PM stepper motor is set at the step angle of 18° with an accuracy of ±7.5% per step. It has been optimized in structure by moving the PCB out of the motor body to make the motor assembly more efficient. An external installation also makes the motor operate more reliably.

Further measures have been taken to keep the motor away from dust by installing a black PBT cover around the PCB. A brass synchronous pulley is added onto the end of extended shaft to transfer a bigger holding torque to the application while our PM stepper motor rotates with a less noise and vibration.

Applications
The motor has found wide use in the time clock, card reader, teaching instruments, and micro-printer.
