NEMA 8 Sub-Miniature Hybrid Stepping Motor

Provides Options for Designers that Require Performance and Endurance in a Small Package

Nippon Pulse America, Inc., Radford, VA - (July 11, 2007) Nippon Pulse America introduces the NEMA Size 8 hybrid stepper motors that produce high speed and torque in a sub-miniature, RoHS compliant package. They are ideal for motion control applications where the benefits of smaller size with high torque are essential. The torque levels reached with this step motor line makes them a cost effective alternative to servomotors in many applications.

The compact and lightweight 1.8º NEMA 8, bipolar hybrid stepper motors provide flexibility in applications with limited space. The new stepping motors measure only 20 mm square by as little as 30 mm long. This makes them one of the smallest stepper motors available that will accurately execute 1.8 degree steps.


o 1.8 degree step angle
o 2 phase design with 4 lead bipolar configuration
o Precise current control when matched to an NPM integrated bipolar chopper driver.
o Rugged front and rear ball bearing construction
o Increased radial and axial load capacity compared to standard tin-can stepper motors
o Runs cooler than most tin-can step motors
o Fast acceleration yet low audible noise
o High torque to inertia ratio

These motors are available in stack lengths of 30, 33, and 42 mm. Depending on the stack length, the NEMA Size 8 motor can produce maximum holding torques (bipolar) ranging from 17.7 to 29.5mNm (2.5 to 4.2oz-in).

The RoHS compliant NEMA Size 8 hybrid stepper motors feature a step resolution of 1.8º (200 steps per rev) in full-step mode; precision-honed stators and ground rotors for tight air gap and maximum performance; 4 leads; and simple, rugged construction for high reliability and long service life. Value-added customizations include coil voltage, double shaft, and lead-wire connector assemblies. Custom windings are available at no additional cost.

These budget priced hybrid stepper motors are for low or high volume production. Applications for the NEMA Size 8 hybrid stepper motors include medical equipment, semiconductor handling, telecommunications equipment, valve control, laboratory instrumentation, medical devices, small machinery, and other automated devices that require precise remote controlled rotary movements in a sub-miniature package size. They deliver accurate open loop control for high performance positioning applications.

The 100-piece price of the NPM Size 8 hybrid stepper motors is $30 in 30mm, $36 in 33mm, and $39 in 42mm stack sizes.

Nippon Pulse America, Inc. is the wholly owned American subsidiary of Nippon Pulse Motor Co., Ltd. Nippon Pulse offers various controllers (boards and chips), drivers (boards and chips), and motors (tin-can, hybrid and linear servo) to cover almost any motion application.
