Working Mechanism
- Electric motors convert electrical energy into mechanical energy for generating motion.
- Force is produced within the motor through the interaction between a winding alternating (AC) or direct (DC) current and the magnetic field.
Features
- Marathon centrifugal pump motors feature clockwise or counterclockwise rotational shafts for delivering speeds up to 3450 rpm.
- They come with double-sealed ball bearings that are mechanically locked on the shaft end to reduce motor friction.
- These units feature a capacitor start or capacitor run motor design for improved efficiency.
- They are equipped with a drip-proof enclosure to permit cooling air to flow through the motor, thus preventing overheating.
- These steel-constructed jet pump motors have a keyed shaft for continuous duty operation and squirrel cage induction to ensure constant speed.
Frequently Asked Questions
What is an open drip-proof enclosure motor?
Open drip-proof enclosure motors allow air to flow through the windings to cool them, preventing liquid drops from falling into the motor at an angle less than 15 degrees from vertical.
What is the difference between single, double and triple-phase motors?
- Single-phase motor: Electricity flows through a single conductor.
- Double-phase motor: Electricity flows through 4-wire conductors (2 for each phase).
- Triple-phase motor: Electricity flows through 3 separate conductors.
Do these motors prevent overloading?
Yes, Marathon jet pump motors have an automatic reset thermal protector to prevent overloads.
