New 51 mm (2.0 in.) Frame Size Harmonic Gear Available for 1.8° Flat Type PKP Series Stepper Motors

Sept. 17, 2019
Ultra-compact, lightweight and stepper motors with improved torque and low backlash.

Oriental Motor is pleased to expand the PKP Series stepper motor product line-up with the introduction of a 51 mm (2.0 in.) Harmonic frame size gearhead for the 42 mm (1.65 in.) PKP Series 2-phase Flat Type. This new combination compliments the 60 mm (2.36 in.) PKP Series Flat Type which is available with a Harmonic gearhead or round shaft. Both frame sizes offer 50:1 or 100:1 gear ratios.

The 2-phase Flat Type is an ultra-compact and light weight entry to the PKP Series of stepper motors and is available in two frame sizes; 1.65" (42 mm) or 2.36" (60 mm) frame size. The Flat Type PKP Series stepper motor can be installed in a narrow space due to its flat profile design where conventional stepper motors would not fit. This makes the Flat Type an ideal solution for robotic applications that require a low profile motor with high position accuracy and repeatability of a Harmonic gearhead.

The new PKP Series stepper motors now uses neodymium magnet in its rotor design, which allows for lower vibration compared to the original PKP Series motors. For the optimal results, use the new PKP stepper motors with their respective CVD bipolar driver.
