H Conventional Series

The H series are high-efficiency, low-loss stepper motors that have a conventional, round frame in NEMA 23, 34 and 42 frame size options. A wide variety of standard windings, connectors and options suit general-purpose applications with holding torques up to 3,958 oz-in (27.95 N-m).

Single and double stack motors are available with both standard and low inertia “-J” rotors. Choose low inertia to produce the highest acceleration rates possible. Low inertia motors are most effective for operation below 2,000 RPM. Choose standard to generate maximum torque.

In addition, they are available in numerous configurations including: flying lead, MS connector or terminal board connection options, optional mounted incremental encoder or encoder mounting provisions, and shaft seal options.

Recommended For Applications That Require:
- High speed capability is critical.
- Short lead time (1-2 weeks).
- Low inertia rotor option for maximum acceleration.
- Splash-proof terminal board plus shaft seal option for IP65 protection (NEMA 34 and 42 only)
- MS connector option.
- Mounted incremental encoder option.
- UL Recognized.
