Does HP matter on condenser fan motor?
Although it is not too difficult to change a condenser fan motor, it is still possible to do it incorrectly. Of course you need a motor that operates at the same voltage, phase, and frequency of the original motor and it should also be the same horsepower.
How do you size a fan motor?
Fan Motors Size Selection. The key indicator for determining fan motor size is fan brake horsepower (BHP), which represents the force needed to brake, or stop, the motor. This is the minimum amount of power needed to operate the fan. Your fan manufacturer will always specify brake horsepower.
How much does it cost to replace a fan motor in an air conditioner?
about $300 to $600
When your air conditioner’s fan motor breaks, it will typically cost about $300 to $600 to replace. However, if your AC fan motor is under warranty, it could cost $100 to $300 – if your AC fan motor is not under warranty, it could cost between $200-$700.
How do I choose the right fan motor?
Using the specifications of the fan blade is the best way to determine the correct horsepower for a replacement condenser fan motor. The diameter, angle and number of fan blades, along with the RPM of the motor, are the pieces of information necessary to make this determination.
How do I choose a fan motor?
The higher the motor speed, the lower the cost, the smaller the frame size and the lower the weight. That means that when fan noise is not an issue, a 3600 rpm motor is preferred over an 1800 rpm motor and an 1800 rpm motor is preferred over a 1200 rpm motor.
How is HP fan motor calculated?
Fans and Blower Horsepower Equation
- P = (Q x p)/(229 x ) or.
- P = (Q x PF)/(33,000 x ) or.
- P = (Q x Pw)/(6356 x ) Where: P = Power, hp. Q = Flow Rate, cfm. p = Pressure, lb/in2 Pf = Pressure, lb/ft2 Pw = Water Gauge, Inches. = Efficiency coefficient. Link to this Webpage: Engineers Edge:
Does RPM matter on a fan motor?
You will need to match the RPM and the HP rating will need to match or exceed the original motor. Don’t mess with “close enough” RPMs. Higher, and you will increase HP of motor needed by some unknown amount and potentially burn out motor.
How do you match a fan blade to a motor?
How is HP fan calculated?
What is RPM in fan motor?
rpm Revolutions Per Minute. Measure of fan speed. TS Tip Speed. The speed of the tip of a fan wheel or prop measured in feet per minute.
How do you calculate HP?
The answer is simple: horsepower is calculated by multiplying the amount of force (in pounds) by the speed (in feet per second). So, let’s say your car’s engine can generate 200 pounds of force and move at a speed of 2 feet per second. The engine horsepower would be 400 (200 x 2).
How do I choose a fan RPM?
Motor RPM for Direct-Driven Fans With the fan wheel mounted to the motor shaft or the fan shaft directly coupled to the motor shaft, the motor speed should match the fan’s operating speed. For example, a 3600 RPM motor at 60 Hz should be selected for fans operating at or within tolerance of 3600 RPM.
How do I know what blower motor I need?
To match a furnace blower motor, you’ll need to look at the make and model number of the blower motor. The details that you need to know include the horsepower, amps, voltage, speed, and shaft size of the motor.
How many amps are in a 1050 RPM motor?
1/10 hp 1050 RPM, 3.4 amps, 115 Volts 60hz. 3 studs on back, 4″ on center. Shaded Pole Motor – Will not replace a motor with a capacitor (PSC).
How long is the shaft of the motor on this motor?
The motor has mounting bolts on both the front and back of the motor. If your motor mounts with a belly band around the motor (5″ Diameter motor), this motor should work fine. The shaft is 3 1/4″ long. 1 Year manufacture warranty.
What controls the speed of a furnace blower motor?
In an HVAC system, motors typically turn the air conditioning fan blade and the furnace blower motor. Newer high efficient motors, such as X13 and ECM motors, have “end caps” that control the motor speeds. These can be removed and replaced separately.
