PJE20T-28E14 Rotary Hybrid Stepper Motor

Hybrid Stepper Motor Technology

The PJE series of hybrid stepper motors from Nippon Pulse are available in sizes from NEMA 8 through NEMA 34. Each frame size is offered in multiple stack lengths and can be fitted with optical encoders. These hybrid stepper motors are ideal for motion control application requiring high torque in a compact package. Nippon Pulse can also provide a variety of customizations including special shaft accommodations, custom mountings, special environmental treatment, or integration of lead or ball screws to convert rotary to linear motion. The PJE20T series is a NEMA 8 hybrid stepper motor (20mm x 20mm frame) with bipolar windings and is available in 2 stack lengths.
