Features
- These PSC motors are equipped with ball bearings for low rotational friction while running at a maximum speed of 1075 rpm.
- They feature a drip-proof enclosure to prevent overheating of motor windings while protecting the motor from rain or airborne particles.
- These motors allow vertical, horizontal or shaft up mounting within the fan's airflow for proper cooling.
- They have a shaft slinger for added safety.
Frequently Asked Questions
How does a PSC motor start?
- After a capacitor start or split phase motor starts, the centrifugal switch on the shaft opens and disconnects the start winding or capacitor.
- The motor then runs using the run winding only.
What is the advantage of a shaft slinger?
Shaft slinger protects the motor from the entry of liquid contaminants through the shaft end bearing.
What is the maximum ambient temperature of Marathon condenser fan / heat pump motors?
These motors can be operated at a maximum ambient temperature of 60 degrees C.
