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 have double sealed ball bearings that are mechanically locked on the shaft end to reduce motor friction.
- These single-phase models with clockwise or counterclockwise rotational shafts deliver speeds up to 3600 rpm.
- They feature a capacitor start or capacitor run motor design for improved efficiency.
- These steel-constructed jet pump motors have a keyed shaft with a continuous duty operation.
- They are equipped with a drip-proof enclosure to permit the cooling air to flow through the motor, thus preventing overheating.
Frequently Asked Questions
How to choose between open and drip-proof enclosure motors?
Open enclosure style motors are ideal for locations with minimum ventilation. Their open style design ensures that the air circulates freely through the motor. On the other hand, open drip-proof enclosures offer ventilation and prevent liquid drips from getting into the motor enclosure.
What is the difference between 1, 2 and 3-phase motors?
- 1-phase motor: Current flows through a single conductor.
- 2-phase motor: Current flows through 4-wire conductors (2 for each phase).
- 3-phase motor: Current flows through 3 separate conductors.
What does class B insulation mean?
These motors have Class B insulation for temperature control. The Class B insulated motors can handle temperatures up to 130 degrees C.
Do these motors prevent overloads?
Yes, these Marathon jet pump motors have an automatic reset thermal protector to prevent overloads.
