AC & DC Motor Repair

Services

Repair Process

In-house rewinding – We have the ability and equipment to rewind any kind of industrial motor, including AC, DC, servo, and spindle motors
Bearing Changes – Bearing care is essential in a motor, and for this reason, it’s standard protocol for us to change the bearings on every repair we perform
In-house Machine Work – We are equipped with the following:
– Lathes
– End mills
– Punch press
– Vertical press
– 30-ton bearing puller
– Vertical cutoff saw
– Dry abrasive blasters
– Coil-winding machine
– Lathe-type undercutter
– TIG, MIG and stick welders

Dynamic Balancing –

– We use vibration-sensing equipment and dial calipers to detect vibration as we run the motor at full RPMs.

– If an imbalance is detected, we remove the rotating group and correct the imbalance using one of our dynamic balancing machines.

– We can perform balancing at NEMA or mil-spec certifications and provide a balancing report upon request.
Dyno Testing – Will test the motor under a full load to ensure a proper long-lasting repair
Cleaning and Painting – Cleaning is crucial because dirt and debris can wreak havoc on a pristine motor. We provide ISO- standard paint which governs the protective paint systems used to provide corrosion protection for steel.
Dynamic Testing – This testing will extract information on the quality of the motor’s power as well as its operating conditions. We will collect the following information:
- Voltage level
- Voltage imbalance
- Harmonic distortions
- Current level
- Current imbalance
- Load level
- Torque and rotor bar signatures

Static Testing – This testing identifies problems with the unit’s components
Testing Three-Phase Motors – This testing includes both dynamic and static test methods which include:
- Earth continuity and resistance
- Power supply
- AC motor winding continuity:
- AC motor winding resistance
- Insulation resistance
- Running amps
Dynamometer Test Applications – This testing is key to the development and testing of electric motors. The dyno allows for variable and full load testing necessary to ensure optimal function.
