What issues should be considered during the maintenance of Simo motors?

Generally speaking, AC servo motors and stepper motors have a relatively long service life, mainly because there are fewer vulnerable parts in these products. Different from brushed motors, brushless AC servo motors and stepper motors basically have no vulnerable parts other than bearings. In addition, due to the absence of brushes and commutators, when the motor rotates, there is no risk of structural short circuits caused by the accumulation of conductive dust, making them basically "maintenance-free".

The requirements for axial force and radial force of stepper motors and servo motors are determined by the motor shaft. The motor shaft is usually much smaller than the bearing values in the bearing design, and the bearing design essentially determines the service life of the motor.

However, sometimes Simo motors still need to be repaired. It could be that the feedback encoder is damaged, or an electrical or appliance accident causes an excessive current in the driver or the motor, thus damaging the windings. Or it might just be a lack of bearing lubrication.

In such cases, many Simo motor users rush to send the motors for repair and often choose the nearest repair shop, or even disassemble the motors by themselves for repair.

Non-professional motor repair service providers or shops lacking relevant experience may overlook some potential problems, resulting in the motor not being able to return to normal in a timely and effective manner. In fact, when choosing the repair service for servo and stepper motors, we need to pay attention to the following aspects:

Whether the motor repair service provider can conduct over-current or over-voltage tests on the finished windings. Otherwise, it may lead to premature failure of the motor, causing additional equipment downtime and production losses.

The calibration of the feedback encoder of Xi'an Simo motors not only requires specialized equipment and instruments but also professional methods and skills. Conversely, it requires a great deal of time and effort from professionals to provide guidance.
