Andres BlancoThe 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.

VSM20B-048S non-captive linear stepper motor with run through lead screw shaft
VSM20B-48S is non captive linear stepper motor with 20mm diameter.
We have three different shaft designs: including Captive / Non-captive / External drive
Captive motor: shaft is fixed, it can not rotate, shaft can only do linear movement.
Non-captive motor: shaft can do both rotational and linear movement. In order to work properly, user have to fix the shaft. User have to use anti-spinning mechanism to stop the motor from spinning, otherwise the motor will rotate in vain.
External drive: The shaft is locked with motor’s rotor, the shaft can only rotate, can not do linear movement. It comes with a plastic nut. Users can assembly their component on plastic nut.
Users can pick suitable shaft design based on different design requirement.
Other parameters, such as step angle, rated voltage, coil resistance and shaft length are all customizable.
