NEMA34 86mm Integrated Stepper Motor Linear Actuator
|
Linear stepper motors can dramatically
reduce cost and save space. There is no coupling, no additional bearing support and no assembly work required. This not only reduce cost but also reduce failure rate due to the less number of components and more simple construction. In applications with small load ratings a linear guide is also not required. The special design and material of the nut secure long life operation.

* We don´t use wave washer and we applied pre-load to the bearings. So the axial play is very small, it comes from the mechanical deform when there is axial load, it should be less than 0.1mm.
** For the motor with screw shaft, there should be no radial load on the screw, otherwise the shaft will be bend and affect the linear accuracy.

Normally the lifetime will typical be as following but will depends on load, force, acceleration, speed, temperature and many other factors.

Standard motors are Class B rated for maximum temperature of 130 °C. Standard protection grade IP42. Motor can also be delivered as a 6 wire unipolar with 30% less force. Other travel per step, special nut and mechanical shaft dimensions/length can also be delivered. Weight and inertia depend upon shaft length. All measures in mm. All electrical tolerances 10%.
