Loher J Ex nA Series Explosionproof Electric Motor

The Loher J Ex nA Series have a modular cooling design which features double-flow inner cooling for a high power density and a homogeneous temperature distribution.

From the Loher J Ex nA Series, there are 2 versions available:
Mounted air-water heat exchanger (JHWK – roller bearings / JHXK - sleeve bearings)
Mounted air-air heat exchanger (JHRK – roller bearings / JHQK - for sleeve bearings)

Loher J Ex nA Explosionproof Electric Motor

Also available for exceptional requirements - such as dust explosion protection.
Corrosion protection using special paint finishes according to the manufacturer's standard or customer's specification.
The motors are available as special version for polar regions down to -40 °C (without pre-heating of the motor) or desert regions up to +60 °C.
Wide range of connection systems for large cable cross-sections, high short-circuit strength or phase-segregated version.
Optimized starting and operating parameters and high efficiency by using copper bar rotors as standard.
All motors have a double flow inner cooling for a high power density and a homogeneous temperature distribution.
