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

Frequently Asked Questions

What is the maximum operating temperature of these Marathon carrier motors?

They can operate at temperatures up to 40 degrees.

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 motors have an automatic reset thermal protector to prevent overloads.
