Hybrid Stepper Motors produce high torque in small package.

Press Release Summary:

Measuring 28 mm² by as little as 32 mm long, bipolar and unipolar NEMA Size 11 Motors will accurately execute 1.8° steps. They are available in stack lengths of 32, 45, and 51 mm, and depending on stack length, they produce max holding torque from 42-117 mNm. Suited for medical technologies and semiconductor manufacturing applications, RoHS-compliant motors include precision-honed stators, ground rotors, 4 or 6 leads, and single- or double-ended shafts.

28mm Hybrid Stepping Motor Provides Options for Designers who Require Performance and Endurance in a Small Package

Nippon Pulse America, Inc., Radford, VA - (February 8, 2007) Nippon Pulse America introduces the NEMA Size 11 hybrid stepper motors that produce high torque in a small, RoHS compliant package. They are ideal for motion control applications where the benefits of smaller size with high torque are essential.

The compact and lightweight 1.8º NEMA 11, bipolar and unipolar hybrid stepper motors provide flexibility in applications with limited space. The new stepping motors measure only 28mm square by as little as 32mm long. This makes them one of the smallest stepper motors available that will accurately execute 1.8-degree steps.

NEMA Size 11 hybrid stepper motors are precision designed for medical technologies and semiconductor manufacturing applications. They deliver accurate open loop control for high performance positioning applications.

These motors are available in stack lengths of 32, 45, and 51mm. Depending on the stack length, the NEMA Size 11 motor can produce maximum holding torques (bipolar) ranging from 42 to 117mNm.

The RoHS compliant NEMA Size 11 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 or 6 leads; single or doubled-ended shafts; and simple, rugged construction for high reliability and long service life. Value-added customizations include coil voltage, encoder mounts, single & double shaft details, 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 11 hybrid stepper motors include X-Y tables, 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 very small package size.

The 100-piece price of the NPM Size 11 hybrid stepper motors is $28 in 32mm, $34 in 42mm, and $37 in 51mm 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.
