The 8 Poles – 50Hz – 230/400V MVE-ExD Explosion Proof Electric Motovibrators are electric motors designed to provide vibration to equipment such as screens, feeders, and conveyors in potentially explosive atmospheres. They have eight magnetic poles within the stator and operate at a frequency of 50Hz. These motors are classified as “ExD” motors, meaning they are designed to contain any internal explosion and prevent it from igniting the surrounding atmosphere. They operate on a voltage of 230/400V and are designed to operate safely and efficiently in potentially hazardous environments.
