    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

7.5 degree Permanent Magnet Linear Stepper Motor 20mm Permanent Magnet stepper motor for 3D Printer Stepper Motor

VSM20-32 captive shaft liner stepper motor,Captive type is a Stepper motor whit a lead screw, when rotor running CW or CCW,the lead screw will go forword or backword. at the same time ,the lead will rotating.

captive shaft: the running mode is up and down running thrust, (the top screw of the motor is used to fix your structure, and can also be customized for other installation methods)
Motor step angle is 7.5 degrees (can also be 15 degrees)
For example:
motor stepper step angle is 7.5 degree, lead pitch is 0.6096mm, when motor stepper rotate one step, the lead moves 0.0127mm for each step of the stepping motor (of course, when you choose different lead pitch and step angle, we can recommend it according to your usage needs


This product is a patented product of the company. It converts the rotation of the motor into a linear motion through the relative movement of the internal rotor and the screw. It is mainly used in valve control, automatic buttons, medical equipment, textile machines, robots and other related fields.
At the same time, the external wiring part can use four terminal posts (light pins) or connecting wires, or FPC FFC PCB, etc. according to customer requirements.
The output part is linear.

Our team has more than 10 years of stepper motor design, development and production experience, so we can achieve product development and auxiliary design according to the special needs of customers!
Customer needs are our efforts, please feel free to contact us!
