    The thruster have arrived correctly. I tested them on the ROV and we are very happy with the result. The epoxy interior finish is very good and the power of the motors in relation to the size is quite good.

Product Description

High Resolution NEMA8 20mm Diameter Bipolar Hybrid Stepper Motor with 500 1000 2000 PPR Optical Encoder

This product is 20.2mm diameter hybrid stepper motor with high resolution optical encoder.

Motor is regular NEMA 8 hybrid motor, and it can by replace by any other hybrid motors.

Lead screw is Tr3.5*4mm pitch trapezoidal screw.

About the encoder, it’s high resolution optical encoder, and we have 500, 1000 and 2000 PPR for you to choose.

PPR means pulse per revolution.

For example, if we use 1000 PPR encoder, when the motor spins one turn, encoder with generate 1000 pulse signals, and it’s very high precision.

This motor is very helpful for high precision control, and closed loop system.


Typical applications:

* Medical Equipment

* Linear Robotic Control

* Precision Calibration

* High Precision Valve

* Other Precise Position Movement


Plus tt has extra low noise and high stability.
