Nippon Pulse Offers Geared Stepper To Replace NEMA11

Nippon Pulse has introduced the PFCU30 integrated geared stepper motor as a replacement option for a NEMA11 hybrid stepper motor. Because it is a tin-can style stepper motor, the PFCU30 is available at a much lower cost than a NEMA11 hybrid stepper motor, potentially 50 percent lower.

With its standard 3/25 gear ratio, the PFCU30 tin-can stepper provides up to 100mN.m of holding torque and has a destruction torque of 300mN•m. In comparison, Nippon Pulse’s PJP28 (NEMA11) hybrid stepper motor comes with a maximum holding torque of 90mN•m.


Like most NEMA11 hybrid stepper motors, the PFCU30 has a 1.8-degree step angle and a 0.9-degree half-step angle, allowing for finer resolution and smoother, quieter rotation.

The PFCU30 features 200 steps per revolution, a resistance of 5.6 ohms, an inductance of 2.1mH, and a starting pulse rate of 365pps. The motor comes in a package with a 30mm diameter, a total length of 36.5mm (end of shaft to back of motor), and a total weight of 75g.

Applications for the PFCU30 geared stepper motor include imaging, medical, and any other system currently using a NEMA11 sized hybrid stepper motor.
