CUSTOM MOTOR INSULATION MATERIALS
PROVIDING SOLUTIONS FOR POWER UTILIZATION EQUIPMENT AND MOTOR APPLICATIONS, INCLUDING ELECTRIC MOTORS SINCE 1951.
Their motor location and application typically identify the insulation components used in these electric motors. The Gund Company offers a variety of insulation components designed for various crucial 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 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. Making it an essential part of electric motors.
