Electric Motor Applications

The Gund Company is a manufacturer and fabricator of engineered material solutions for power utilization equipment, including electric motors. The insulation components used in these electric motors are typically identified by their location and application within the motor. The Gund Company offers a variety of insulation components for the following areas of electric motors:

  • Rotors: The rotor is the moving component of the electromagnetic system in the electric motor. Its rotation is due to the interaction between the stator windings and the magnetic fields which produce a torque around the rotor’s axis and mechanical power to the shaft.
  • Stators: The stator is the stationary part of a rotary system and utilizes the incoming power to apply electromotive forces to move the rotor.

Electric Motor Insulation

Insulation components for electric motors have to be precisely measured, machined, and installed. The Gund Company employs an expert staff to run our state of the art fabrication equipment. Coupled with our rigorous Quality Assurance program and “in process” inspections, The Gund Company can offer our customers high-quality products that meet the challenging application demands of the electric motor market.
