Marathon Electric imPower 3 Speed Round Frame Pool Pump replacement motor 1.25HP
Price: $449.00
Product name: Marathon Electric imPower 3 Speed Round Frame Pool Pump replacement motor 1.25HP
Product code: RB053

Maximize efficiency with imPower

• Lower noise – virtually silent during filtering

• Increased reliability – Totally Enclosed Fan Cooled (TEFC) construction with high strength bearing system

• Low weight – 14lbs lighter than Marathon C1245 induction motor

• High efficiency over entire speed range (~80%@1.25 HP)

Ease of installation

The imPower motor is designed to be a drop-in replacement for an induction motor. Here are three easy ways the imPower can be installed:

1) Directly to a power source and controlled by the homeowner/user selecting the speed using one of the three buttons on top.

2) Directly to an Intermatic timer (either 1 or 2 speed) which is set by a pool professional. If imPower is connected to a 1 speed timer, the

motor will be turned on or off. If imPower is connected to a 2 speed timer, the motor can change speeds and be turned on or off.

3) Directly to a third party system controller which is set by a pool professional. The system controller is an electronic system which

communicates to imPower using low voltage DC signals. The imPower motor will respond to the programs set by a pool professional.

TEFC Construction

 

 

 

 

Because of its axial flux brushless-DC, permanent-magnet design, the imPower motor is inherently more efficient than a conventional induction motor. The axial flux motor uses significantly less material and is lighter and more compact compared to a typical induction motor. An advanced electronic control allows the power to be easily controlled while maintaining a high efficiency level. The control allows the motor to operate at lower speeds, leading to a significant energy saving.

 

Simple, intuitive three-speed operation

imPower is designed to run at one of three speeds making it ideal for pumping applications. The affinity laws of hydraulics state that if you halve the speed of a motor, the power is reduced by a factor of eight. The lower speeds offered by imPower allows a pump to filter at a lower speed allowing a homeowner to take advantage of energy savings. The homeowner will continue to have the ability to run the motor at high speed for cleaning cyles or water features. The speed control requires no electronic or programming knowledge, with the three speeds being preset at the factory. Just plug the motor in to a single speed timer, allowing it to operate at the low speed default setting after a brief priming cycle. Subsequent speed selections can be made using the buttons on the integrated topside interface. Alternatively, the imPower can also vary speeds automatically when connected to a two speed timer or via digital inputs from a variety of third party system controllers.
