The speed regulating motor is a kind of motor that changes the speed of the motor by changing the series, voltage, current, frequency, etc., so that the motor can achieve higher performance.

Bearing is an important part of speed regulating motor equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, ensure its rotation accuracy.

Due to manufacturing factors, the difference in material uniformity, even if the same material, the same size of the same batch of bearings, used under the same working conditions, its life length is the same.

So how to choose the right bearing for the speed control motor? Inseparable these two aspects:

Adjustment: If the adjustment accuracy of the shaft bearing seat is poor the shaft is flexed due to load, then the inner outer rings of the bearing are eccentric. Non-aligning rolling bearings can only control the allowable eccentricity by combining internal clearance. If the desired Angle of inclination is to occur between the inner outer rings, then the bearings should be selected such types as thrust ball bearings with aligning gaskets, aligning ball bearings aligning roller bearings. The allowable inclination Angle of the bearing varies depending on the bearing type, internal clearance load conditions. If the eccentric Angle in the bearing is greater than the allowable Angle, internal bearing damage may occur. Please contact the technician!

Stiffness: When the rolling bearing is loaded, the contact area between the bearing ring the rolling element will produce elastic deformation. The amount of this elastic change will vary depending on the load, bearing type bearing size. If the bearings of the same size series are compared, the roller bearing has much higher stiffness than the ball bearing; Compared with bearings of the same type, bearings with larger sizes have higher stiffness than bearings with smaller sizes.
