    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

18 Degrees Step Angle M3 Lead Screw Linear Stepper Motor 15 Mm Applicable To Medical Devices, Etc 


SM15-80L is a stepping motor with a diameter of 15mm. The screw pitch is M3P0.5mm, (Move 0.25mm in one step. If it needs to be smaller, subdivision drive can be used), and the effective stroke of the screw is 80mm. The motor has a white POM slider. As it is a mold production, it can save costs. It can also customize the slider made of brass according to customer needs. However, the slider needs CNC processing, so the cost is relatively high. Considering the cost and the structure allows, it is recommended that the plastic slider be preferred for production

The greatest advantage of the brass slider is that it is supported by two linear bearings, which provide strong support for the slider and ensure that the slider can move smoothly even under high load.

Therefore, the brass slider has better stability and higher price is fully justified.

For the screw rod stroke, considering your installation space, we can also customize the bracket with short stroke to save installation space
