Electric Rotary Actuators
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.
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.
Match with Any Servo Drive
The ER Series motor can be matched with our digital control, the SV Series, to provide a servo system suitable for hazardous duty. Alternatively, these motors and gearmotors are compatible with nearly any manufacturers' amplifier.
Exlar's Unique T-LAM Stator Technology
Exlar's ER Series rotary motors and gearmotors offer a very high torque to size ratio when compared to other suppliers' motors. All of Exlar's motors utilize T-LAM, an innovative winding designed for efficiency, power and durability.
This design offers several advantages over traditional winding designs for a more efficient and powerful motor. Built for durability, the individual segments, more robust insulation, the magnets and potting all provide a more thermally robust motor design -- a design yielding a 35 to 70% torque increase in the same package size! T-LAM motor designs have Class H insulation systems compliant with UL requirements.
