Description
For hazardous duty environments with constant exposure to flammable gasses or vapors* Exlar’s ER Series rotary explosionproof motors and gearmotors provide an excellent solution. Exlar’s motors utilizing T-LAM™ technology, an innovative segmented winding, have been designed for efficiency, power and durability and provide a very high torque-to-size ratio when compared to other suppliers’ motors.
Explosion Proof Rating
ER Series motors are rated for Class I, Div 1, Groups B, C and D. The classification of "Class I" means that flammable gases or vapors may be present in the air in quantities sufficient to produce explosive or ignitable mixtures. "Division 1" means that hazardous concentrations in the air may exist continuously, intermittently, or periodically under normal operating conditions. "Group B" allows for atmospheres containing hydrogen, or gases (or vapors) of equivalent hazard, such as manufactured gas. "Group C" allows for atmospheres containing etyhyl-ether vapors, ethylene or cyclo propane. "Group D" allows for atmospheres containing gasoline, hexane, naptha, benzene, butane, alcohol, acetone, benzol, lacquer solvent vapors, or natural gas. ER Series motors are not rated for operation in atmospheres containing acetylene.
Compact Gearmotor
The gearmotor comprises a brushless permanent magnet motor optimized for use with an integral planetary gear set. Through the uniform load sharing of several gears acting in concert, planetary gearheads provide a very compact, reliable solution providing high torque, low backlash and low maintenance.
