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.
