The double-shielded ball bearings reduce friction for smooth & continuous operation in demanding applications.
These motors have horizontal / shaft down orientation, allowing proper lubrication with every stroke for reducing seal wear and inhibiting corrosion.
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.
