Captive Linear Stepper Motor

The nut of the Captive Linear Stepper Motor is integrated with the motor rotor, and the screw shaft passes through the nut in the center of the motor rotor. The screw shaft drives a plunger forward and backward. The plunger is supported by the guide bush on the motor. This structure allows the rotating shaft (plunger) to move forward and backward independently. No separate auxiliary action is required on the screw or nut. Provides NEMA8, 11, 17 and 23 base sizes, various body lengths and a wide range of screw diameters and leads to choose from.

NEMA 8 Captive Linear Stepper Motor

NEMA8 (20mm) Captive Linear Stepper Motor has the characteristics of small size, high performance, long durability, low noise and high efficiency. The nut is made of polymer material, self-lubricating and maintenance-free. At the same time, we provide a variety of motor lengths, a variety of screw leads, and a variety of screw strokes for customers to choose freely.
