A good motor repair is a collaboration between you, the customer, and GPR.

If you can supply the following information it will be very helpful:

• Complete nameplate information, including manufacturer, horsepower, speed, voltage, phase, enclosure, catalogue, part and/or model number, frame size, and serial number.

• What does the motor operate? A fan, blower, conveyor, pump?

• How does the motor drive the load? Direct drive, belted?

• Is there auxiliary equipment attached like a clutch, gearbox, or brake?

• Why do you think the motor needs repair (it doesn’t run, preventative maintenance, etc.)?

• What is the motor’s repair history? Is it a “problem motor”?

• How is the motor started (soft start, adjustable speed drive, part winding start)?

• What is the operating environment (in/outdoors, hazardous fumes or dust, water spray)?

• When do you need the motor back? Will you authorize overtime work if necessary?

• Is the motor still under manufacturer’s warranty?

FAQ:

What are my repair options?
In the case of standard motors, repair may not always be the best option. GPR should be able to offer premium efficiency replacement alternatives to repair which may save you operating dollars. Bear in mind, however, that many motors are special and not readily available off the shelf. This may make repair the best option.

How can we get the motor in for repair?
GPR offers free pickup and delivery for our service customers.  Please call Mick in Shipping & Receiving at 888-532-5900 to arrange pick up or delivery.  In the case of a very large motor or a motor that is located at a remote site, some coordination with a crane or other material handling equipment may be necessary.

What is involved in the repair?
After GPR inspects the motor, we will tell you if the motor needs rewinding or just bearing replacement and clean up.  We will tell you what tests we have performed to substantiate these findings.

How long will it take to complete the repair?
Remember, a good repair, including rewind, can take several days or more. Cutting corners on repair can cost you money and even result in premature motor failure.

What will the repair cost?
GPR will strive to give you an accurate cost estimate for repair. Remember, however, that repair costs can vary once we actually start the repair because we may find hidden problems that were not readily apparent on the first inspection.  Please be prepared to work with us to obtain the best repair possible. 

Decreased motor efficiency translates to higher electricity use and a higher energy bill.
In short, don’t cut corners in the repair of your motor.  A good motor repair takes time.
