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 centrifugal fan motors have permanently lubricated ball bearings that are mechanically locked on the shaft end to reduce motor friction.
  • They feature steel constructed frames for structural rigidity and are supplied with a rigid mounting base.
  • These units are equipped with a TEFC open drip-proof enclosure to permit the cooling air to flow through the motor, thus preventing overheating.
  • These 1-phase units with a high starting torque allow efficient power supply with continuous duty and quiet operation.

Standards and Approvals

  • CSA
  • UL
  • NEMA

Frequently Asked Questions

What is the difference between 1, 2 and 3-phase motors?

  • 1-phase motor: Current flows through a single conductor.
  • 2-phase motor: Current flows through 4-wire conductors (2 for each phase).
  • 3-phase motor: Current flows through 3 separate conductors.

Do these motors prevent overloads?

Yes, these Marathon centrifugal fan motors have an automatic reset thermal protector to prevent overloads.

How to choose between open and drip-proof enclosure motors?

Open enclosure motors are ideal for locations with minimum ventilation. Their open design ensures that the air circulates freely through the motor. On the other hand, open drip-proof enclosures offer ventilation and prevent liquid drips from getting into the motor enclosure.
