Stepper motor is an open-loop control motor that converts electrical pulse signals into angular displacement or linear displacement. It is the main executing component in modern digital program control systems and has a wide range of applications. Do you know the reason for overheating of stepper motor bearings? Below, the editor will explain it to you.

1、 The stepper motor itself:

1. The fit between the inner and outer rings of the bearing is too tight

2. There are issues with the shape and position tolerances of components, such as poor coaxiality of machine bases, end caps, shafts, and other parts

3. Improper selection of bearings

4. Poor lubrication of bearings or incomplete cleaning of bearings, with impurities in the lubricating grease

、 In terms of usage:

1. Improper installation of the unit, such as the coaxiality of the stepper motor shaft and the dragged device shaft meeting the requirements

2. Pulling the pulley too tightly

3. Poor maintenance of bearings, insufficient or expired lubricating grease, drying and deterioration
