Can I Put a Speed Control on My Explosion Proof Motor?
Facilities that manufacture volatile materials, such as rubber or metals, require the use of explosion-proof motors for automating conveyors. These hazardous-area motors need speed-control devices that do not compromise the specialized functioning of the motors.

Identification
-
Explosion-proof motors are specially designed for emitting lower levels of heat than a typical automation motor. The motors are useful for automating production facilities with highly explosive products, such as fuels or chemicals. An external speed-control device changes the speed of the motor, as needed, to maximize production times.
Uses
-
A speed-control device can connect to an explosion-proof motor, but they must be matched properly, states Rockwell Automation. Rockwell suggests working with one manufacturer for matching a customized motor and a speed-control configuration.
-
Significance
-
An explosion-proof motor overheats when used with an improperly matched speed-control device. The electrical current and voltage levels within the speed-control device must not exceed the motor's power requirements, so as to avoid a potentially dangerous breakdown of the automated system.
