Blower Motor

Reliable Blower Motor

Having a comfortable seat and a clean cabin is one of the important reasons for a construction machine user to ride comfortably, and another key factor is good ventilation. The blower motor cooperates with the fan switch to ensure the air temperature in the cabin, so as to ensure that the driver can work more efficiently. At FridayParts, we offer a range of carefully selected blower motors. You can easily find the right one for your needs by searching for the brand or model of your equipment followed by the keywords 'blower motor' and other cab and a/c parts you need.

What is a Blower Motor?

It consists of two main parts, including the motor and fan assembly.

Blower motor parts list

Electric motor

The most important part of the blower assembly is the motor, which is responsible for driving the blower wheel or fan to move air through the HVAC system. It can be brushless or brushed.

Motor blower housing

The blower housing is the shroud around the motor that contains the housing of the motor and blower wheel or fan, and sometimes the entire blower assembly. The casing is mainly used to protect the motor, and coating or painting on the surface can effectively prevent corrosion.

Blower wheel

The blower wheel is a rotating fan that works by sucking in air and pushing it through the HVAC system. Usually, it's a round wheel made of plastic with corners to form the blower blades. The blower wheel assembly must be kept clean and free of debris for the blower motor to function properly. Failure to do so may result in overheating of the motor or damage to the blade.

Bearing

Bearings are used to support the motor shaft and reduce friction during operation.

Control module

The control module is responsible for regulating the speed and operation of the blower motor and can be integrated with the vehicle's HVAC system controls.

Capacitor

Capacitors can help give the motor an extra boost of power during start-up.

How a Blower Motor Works?

The working principle of the blower motor of construction machinery equipment is similar to that of a centrifugal fan, which is a device that absorbs air mechanically. The blower has a high-speed rotating impeller or rotor to drive the air movement and uses centrifugal force to make the airflow along the involute-shaped casing to the outlet of the fan. The high-speed airflow has a certain wind pressure, and the new air enters and replenishes from the center of the casing.

How do You Know If the Blower Motor is Bad?

Low/no airflow

This is the most obvious sign of a problem with the blower motor. The airflow of the vent is limited, and the airflow is very low at this time, which may be caused by the motor being blocked by dust and dirt. You can go to a repair shop and seek the help of a professional mechanic. If there is no airflow at all from the vent, it means you need a new blower. It's also a good idea to check things like thermostats, relays, or fan controls.

Unusual whirring or rattling noises when turning on the heater

Unusual sounds could be worn on bearings or other internal components, which are some of the sounds a blower can make when it fails.

The circuit breaker keeps tripping

A failed blower motor will trip the circuit breaker. (Don't rule out the possibility of a failed capacitor, which would also trip the breaker)

Blower overheating/burning smell

If your blower motor is overheating, the vents will emit a burning smell and may even burn. If the blower stops when you run the heat, this is an indication that the system is shutting down to prevent electrical damage.

Reasons Why The Blower Is Not Working

1. Fuse failure;
2. The blower relay fails;
3. There is a failure inside the blower motor;
4. The power transistor or blower switch is faulty;
5. Line failure;
6. The air conditioner control device is malfunctioning.
