Haydon Kerk's rotary motors are built to provide exceptionally high torque to size ratios. By utilizing a patented enlarged rotor with low inductance coils, the motors provide superior torque and continuous, reliable high performance. At rated voltage, the 46 mm motor produces 16 oz.-in. of holding torque, the 36 mm motor produces 4.5 oz.-in., the 26 mm motor produces 1.8 oz.-in. and the 20 mm motor produces 0.65 oz.-in. Optional rare earth magnets may be specified for even higher torque. Bronze sleeve bearings are standard, ball bearings are also available.
Features:
- High Energy Neodymium magnets
- Bipolar & Unipolar windings with 5 & 12VDC ratings
- 7.5° and 15° degree step angle
