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.
Are Marathon condenser fan / heat pump motors prone to overheating?
These motors have automatic thermal protection, preventing the motor from overheating in low ventilation environments.
Do Marathon condenser fan / heat pump motors require frequent lubrication?
These motors have pre-greased ball bearings that are inside the motor enclosure and do not require frequent lubrication.
How to install Marathon condenser fan / heat pump motors?
These motors have a long shaft directly mounted onto the load / fan. The motor is connected to the fan assembly using thru bolt mounting.
