15BY20L PM Stepper Motor
Detailed Product Description
- The housing size at 15mm.
- PM stepper motors are comprised of permanent magnet rotors with no teeth, which are magnetized perpendicular to the axis of rotation.
- 15mm PM stepper motors are formatted at the step angle of 18°with 2-phase.
- The holding torque currently ranges from 25g.cm to 40 g.cm or it can be modified to your OEM designs.
- Have been optimized in construction by building up with the external flexible printed circuit (FPC for short).
- The end of extended shaft is assembled with a brass synchronous pulley,
- Operates with a less noise and vibration while the holding torque can be accordingly increased 10 times if the speed ratio is normally determined at 1:10.
