Cast Iron Motors

Elvem cast iron motors have SKF bearings as standard, PTC thermal circuit breakers and external brass grease nipple for periodic lubrication of bearings
The ground terminals are places outside and inside of the terminal box.
The fins are designed to ensure uniform cooling.
Painting is done with multiple cycles to provide the motor with excellent protection against oxidation.
