Features
- These motors have TEAO (totally enclosed air over) enclosures that must be installed within the airstream for proper cooling of the motor windings to prevent overheating.
- They are incorporated with ball bearings to exhibit low friction loss in high-speed operation and a variety of temperature ranges, preventing wear and tear of the rolling component.
- They come with resilient base-extended studs for suspending the motor to dampen vibrations and noise during motor startup.
- These units are integrated with an automatic thermal protector that shuts off the motor during excessive heat generation and reset the power as soon as the motor cools down.
Standards and Approvals
- UL
- CSA
Frequently Asked Questions
What is a continuous duty operation?
Continuous duty operation carries a constant load without exceeding the stated temperature to reach thermal equilibrium.
What is the advantage of a permanent split capacitor?
PSCs (permanent split capacitors) are permanently connected to the motors to produce high-starting torque, ideal for use in HVAC systems. These units have the same capacitor & capacitor phase in the circuit for both starting and running operation as opposed to single-phase motors which use the capacitor phase only during the motor start-up.
In which direction can the motor be rotated?
Poultry farm motors can be rotated in both clockwise and counterclockwise directions.
