Original Press Release

Stepper Motors with 10mm and 20mm Diameters

Press release date: December 11, 2012

Nippon Pulse has introduced two of its smallest stepper motors to date, the PFC10 and PFC20 2-phase, tin-can series. The PFC10 motor has a 10mm diameter and the PFC20 a 20mm diameter. Both motors are suited for design into systems requiring small motor solutions including valve control, fluid dispensing, gaming machines, and medical devices. Both motors come standard with connectors to ease the integration into systems.

A bipolar motor, the PFC10 offers 1.0mN•m of holding torque, a step angle of 18 degrees, a starting pulse rate of 960pps, 20 steps per revolution, a rated voltage of 2.7V, 20 ohm resistance, inductance of 3.2mH, and a rated current of 35mA/phase. The PFC10 stepper motor weighs just five (5) grams.

Also a bipolar motor, the PFC20 features 10mN•m of holding torque, a rated voltage of 8.9V, a rated current of 89mA/phase, a step angle of 18 degrees, 20 steps per revolution, a starting pulse rate of 370pps, resistance of 100 ohms, and inductance of 47mH. The PFC20 weighs 35 grams.

Nippon Pulse offers the PFC20 motor in a 'thin stack' design (PFC20T). The PFC20T offers 4.4mN•m of holding torque and a rated voltage of 8.7V. The PFC20T is 21.7mm in height while maintaining the 20mm diameter.
