MARATHON MOTORS Blue Chip Severe Duty Motors, Kiln Duty, TEAO, Rigid Base, Three Phase

Marathon kiln AC motors drive fans and conveyors in kiln-drying operations (such as drying wood). These TEAO motors must be mounted within the airstream. They can be used with variable frequency drives.

Working Mechanism

  • A basic alternating current motor consists of a wire coil and two fixed magnets surrounding a shaft.
  • When an alternating current (AC) charge is applied to a wire coil, it transforms into an electromagnet.
  • The electromagnet produces a magnetic field.
  • As the magnetic field is constantly changing due to rotation, it produces an electric current inside the rotor, according to the law of electromagnetism.

Features

  • These Blue Chip Series motors are made entirely of cast iron for rigidity and reduced vibration.
  • They are completely corrosion resistant, owing to the internal & external epoxy paint finish.
  • These units are equipped with CR200 corona-resistant magnet wire, which improves voltage endurance and thermal properties.
  • They feature Normally Closed thermostats in the Class H insulation system (one per phase).
  • They have heat-stabilised ball bearings and high-temperature grease for smooth operation.
  • These units are suitable for inverter use, owing to the 20:1 variable torque with a service factor of 1.
  • Their extended grease tubes can be regreased for long service life.

Standards and Approvals

  • UL
  • CSA

Frequently Asked Questions

What are TEAO motors?

The frame or enclosure of totally enclosed air-over (TEAO) motors is dust-tight. They can be installed in the airstream where the air movement generated by the fan cools the motor.

What is the maximum ambient temperature that these motors can handle?

90 degrees Celsius.

What is the length of the lead?

8 feet.
