Selecting Vendor-Partners and Parts Storage
One of the keys to the success of any motor management program is the selection and relationship with vendors.
A common challenge to the development of a program is that there will be a reduction in the demand for large cost repair and parts. This can have a negative impact on the security of a vendor, unless changes also occur within the vendor and the relationship of the vendor and the company.
The vendor can survive changes within their customers by changing the way they do business. For instance, by offering PdM and CBM services, troubleshooting and RCFA support, the vendor can provide value in new areas that have higher profitability than standard repair. Additional services can include parts storage and maintenance and field manpower support.
Within the company, the selection of the vendor becomes very important. As the company’s program expands, the proper vendor selection and relationship can make the difference whether the program succeeds or fails. Proper selection should include an agreed method of communication, specifications and evaluation/grading of the vendor on a regular basis.
In many motor management programs, the electric motor repair shop or distributor, may be involved in storing spare motors. Even in this case, monitoring how the motors are stored is vital. In the first place, the motors should be stored in an area that is maintained above the dew point or a space heater installed to avoid potential winding and bearing failures. The motor shaft must also be turned periodically and the storage area must be away from heavy traffic or machines which will cause vibration damage to the motor bearings.
