Explosion Proof Motors

Electrical Motors are electromechanical devices that convert electrical energy to mechanical energy by producing a rotating force (torque) measured in revolutions per minute (RPM) and horsepower (HP). Medium size motors are designed and built to operate at 60 Hz with three phase voltage at 230 volts, 460 volts and 575 volts. These motors are used to drive compressors, pumps, fans, machine tools, conveyers and other processing and materials handling equipment in industrial sectors.
Explosion Proof Motors are designed for industrial and commercial machinery located in damp, dusty or dirty environments. They are also suitable for use with Variable Frequency Drives (VFDs). Motors can create an explosion by one of two means. A motor surface gets so hot during operation that it ignites dust, vapor or gas. A single arc from a motor malfunction ignites an ambient material. Explosion proof motors are required for industrial applications with the presence of highly combustible materials. Explosion proof does not mean that the motor will never explode, rather it has features that prevent an internal motor explosion from igniting a combustible atmosphere. The motors have a 1.15 service factor and meet NEMA standard requirements including Class F insulation and IP55 protection.
