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 Globetrotter general-purpose motors feature aluminium frame construction for corrosion resistance and thermal conductivity.
  • These IE3 efficient motors reduce operating costs and increase energy savings while delivering speeds up to 3600 rpm.
  • The ball bearing is mechanically locked on the shaft end to reduce motor friction.
  • They offer continuous duty cycle operation with clockwise / counterclockwise shaft rotation.
  • These triple-phase units having a totally enclosed fan-cooled enclosure allow air to flow through the motor and prevent overheating.
  • They permit flange / base horizontal mounting and have MAX GUARD Class F insulation with NEMA premium efficiencies.

Standards and Approvals

  • CSA
  • UL
  • CE
  • NEMA

Frequently Asked Questions

What is the difference between single, double and triple-phase motors?

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

What does continuous duty operation mean?

A continuous load is where the highest current is expected to operate continuously for three hours or more.

What is the difference between TEBC and TEFC motors?

Totally enclosed blower-cooled (TEBC) motors are virtually identical to TEFC motors with the exception that the motor body is cooled by a separate "blower" positioned on the body rather than by a shaft-mounted fan while the motor is working at a high speed.
