High-Speed Step Motors Are Two-, Four-Phase Types

Using precision machining and rare-earth magnets, the H series motors provide more than 25% more torque, in certain applications, compared with comparable sized conventional hybrid steppers, it's claimed. Offered in NEMA frame sizes of 17, 23, 34 or 42, there are models for unipolar or bipolar operation. Benefits are high speed, low noise, low vibration and resonance, high positional accuracy, and operation well-suited for micro-stepping.
