Motor and generator winding services suppliers specialize in producing custom motors, generators and custom windings per customer specifications, as well as companies that specialize in motor repair and refurbishing.  Motor types that are commonly wound by suppliers of motor and generator winding services include brushless motors, brush motors, linear motors, power generators, servo motors, stepper motors, switch reluctance motors, torque motors, and traction motors.  Motors can be single phase or polyphase (3-phase).  A single phase motor has a single alternating current source.  A three phase or polyphase motor is for use with three-phase power, motors provide efficient service for moderate to hard to start equipment such as pumps, blowers, and air-compressors.  Common applications serviced by suppliers of motor and generator winding services include avionics and aerospace, automotive, industrial, marine, medical, military, motion control, and power generation.  

Specific services offered by suppliers of motor and generator winding services include design assistance, prototyping, production facilities, CAD or CAM support, rewind and refurbish, and stator assembly.  Suppliers with design assistance assist with concepts, manufacturing costs, manufacturing techniques and material considerations. Supplier may also be able to assist in upgrading or redesigning, re-evaluating or modernizing existing products to increase performance and/or reduce manufacturing costs. Some suppliers offer material sourcing and CAD modeling as well.  A vendor with prototyping capabilities has the capability to quickly produce a prototype for visual or tryout inspection.  A vendor with production facilities has the ability to run production quantities at their facility.  CAD or CAM support entails assistance in designing components more efficiently fabricated by machining processes, generating CAD drawings or process engineering.  Some suppliers can provide rewinding and refurbishing services.  Vendors providing stator assembly manufacture and sell custom stator / winding assemblies.
