Vibrator motor: When the repair risk can be too great

Here's part of a 4kW Friedrich vibrator motor that we received for repair. After dismantling and inspecting it, significant electrical and mechanical damage was found.

The windings had failed, both the male and female spigots were significantly worn and the bearing housings showed evidence of wear. We could have repaired this vibrator to the best of our ability, and that may have been more cost-effective than replacing it.

But there is always an element of risk in doing such significant mechanical repair work on a vibrator motor – and on this occasion we decided the risk was too great. Due the massive mechanical stresses these vibrators are subject to, any mechanical weakness will quickly lead to failure.

For us, clear and honest communication with the customer – perhaps, on occasion even talking ourselves out of a job – is the best policy, It helps to establish a good working relationships and build trust which is critical.

So we have offered to replace the vibrator motor with a new model and we await the customer's response.
