Working Mechanism
- Electric motors convert electrical energy into mechanical energy for generating motion.
- Force is produced within the motor through the interaction between a winding alternating (AC) or direct (DC) current and the magnetic field.
Features
- Marathon carrier motors come with an open-air over or drip-proof enclosure to permit the cooling air to flow through the motor, thus preventing overheating.
- They are further equipped with permanently lubricated ball bearings to reduce motor friction.
- These units feature a 3-phase design operation to deliver constant power and provide vibration-free & smooth performance at speeds up to 3450 rpm.
- These products are made of steel to ensure structural rigidity.
Standards and Approvals
- CSA
- UL
