Buy Condenser Fan and Heat Pump Motor Applications
GE Industrial Systems is the industry leader for producing motor products for condenser fan and heat pump applications, with our NEMA 48 frame product line leading the way. Recent additions to the condenser fan and heat pump motor markets include a redesigned NEMA 42 frame Vision motor and a sub 42 frame motor (95 mm) which both utilize a cap/can design over the standard shell and end shield design.
The main features and benefits include points which distinguish the condenser fan and heat pump motor applications from the rest of the manufacturer’s products. The vital features are that the motors can be used in vertical applications with the shaft facing either an upward or downward direction .The second feature that stands out is the use of standard shaft flats which easily allow operation with many different fans or blower wheels. Motors are available with quick-connect terminals for easy installation. Many different motor mountings are compatible, including belly bands, resilient rings, a resilient base, standard lug mount, or GE's special Torsion Flex lugs
The main application of condenser fan and heat pump motor is in a rooftop unit .This unit packs complete refrigeration, heating, and air-handling capability into a single box. Rooftop units have one condenser fan and motor for about every 5 tons of cooling capacity. These propeller fans are usually coupled directly to one-horsepower induction motors. The condenser motor operates in much more difficult conditions than the evaporator fan motor: vertical mounting places a thrust load on its lower bearing, the stream of hot condenser air makes it more difficult to cool the motor, and the motor is exposed to rain and snow .Replacement costs for a typical condenser fan motor on a commercial rooftop unit vary by region and equipment, but are usually about half equipment and half labor.
Condenser fan motors on most new rooftop units come with sealed-cassette ball bearings that need no lubrication. Excessive noise, vibration, or heat at the bearing indicates that the cassette should be replaced.
Rapid on-off cycling of a condenser fan (three minutes or less) leads to poor control of the refrigeration system and can wear out the fan motor prematurely. This problem is often caused by a too-narrow dead band on the condenser fan's head-pressure controller. A healthy differential (20 to 50 pounds per square inch) between cut-in and cut-out pressure set points prevents rapid condenser fan cycling.
GE is an industry leader in HVAC applications, and they are well known for producing some of the best motors available. Specializing in heat pump and condenser fan applications, the GE NEMA 48 line is among the most popular pump frames available. GE continues to innovate, and they have recently redesigned their famous NEMA 42 motor to work in standard shell design systems.
One of the primary advantages of using GE motors for heat pumps and condenser fans is that they can be used in a vertical application. Many motors only function horizontally, and installing them vertically can lead to wear and damage over time. Thanks to GE's engineering efforts, their pumps and motors can be used at any angle needed. Another benefit to GE pumps is that the use standard shaft flats. These flats allow for a versatility that most of the motors cannot match. It also allows motors be connected and installed quickly, and any parts that need to be repaired can be accessed without difficulty. This design enables easy connection to standard mountings. Resilient base mounts, standard lug mounts, resilient ring mounts, belly brand mounts and GE's own torsion flex lugs mounts will all work with this design.
Heat pumps and condenser fans are most often used in rooftop units. As a result, motors must be able to work in outdoor environments. These rooftop units often also contain air-handling devices, heating elements and refrigeration elements are contained within a single box. Because of this, vibration and other potential sources of wear are common. By relying on GE motors instead of subpar motors, it may be possible to avoid potential issues. Rooftop units are generally used in large structures, and an HVAC system that goes down can cause severe problems. Those in charge of HVAC systems will want to ensure that they are using only the best parts available.
GE is a leader in a number of industries, and those who use their parts understand how well they are made and how durable they are. When it comes to motors, GE is among the best in the industry. That said, systems need to be properly maintained, and regular inspections are needed to ensure that parts are not wearing down prematurely. As great as GE parts are, HVAC systems still need proper upkeep.
