Features

  • They come equipped with thermal protectors that are sensitive to temperature rise and protect the motor against overheating due to overload. These protectors can automatically reset after the motor has completely cooled.
  • They feature an external slinger to keep the bearings protected from moisture and contaminants.
  • Models, such as 048A17T96, come with a TEAO (Totally Enclosed Air Over) enclosure installed in the airstream where the air movement generated by the fan passes over the motor to cool it.

Standards and Approvals

  • UL
  • CSA

Frequently Asked Questions

What are the uses of double shielded ball bearings?

The double-shielded ball bearings reduce friction for smooth & continuous operation in demanding applications.

What is the purpose of horizontal / shaft down orientation?

These motors have horizontal / shaft down orientation, allowing proper lubrication with every stroke for reducing seal wear and inhibiting corrosion.

What is the advantage of a permanent split capacitor?

Permanent split capacitors or PSCs are permanently connected to the motors to produce high-starting torque, mainly used in HVAC appliances. These motors have the same capacitor & capacitor phase in the circuit for both starting and running operation compared to single-phase motors which use the capacitor phase only during the motor start-up.
