As we consider our quest for warm homes in the winter and cool homes in the summer, it’s easy to overlook the tremendous impact shaded pole blower motors have in making sure our HVAC systems are running efficiently. Here at FENG YIN we know the important of these simple and nifty little motors and we want to share this knowledge with you all.
Shaded Pole Motors Shaded pole blower motors are a special type of single-phase AC induction motor which are typically used in small household appliances such as fans and heaters. The term “shaded pole” comes from the construction of the motor, in which a shaded or uninsulated coil placed on one side of the pole causes a rotating magnetic field that drives the motor.
Shaded Pole Blower Motor The big secret about shaded pole blower motors is their basic design. They are also relatively easy to produce and reliable, and are therefore employed widely and cost-efficiently in many applications. Also, shaded pole blower motors are known for being quite and producing little vibration, making it a great choice when you need to consider noise.
Shaded pole blower motors are widely applied in many household appliances such as refrigerator, air purifiers, and exhaust fan. They are also prevalent in commercial establishments, including vending machines and refrigerator display cases. With their small size and cheaper price tag, these sensors are becoming popular amongst the manufacturers who prefer to reduce the production cost.
Units powered by shaded pole blower motors create a magnetic field which induces the motor’s rotor to turn. When electricity is supplied to the motor, the current passes through a shaded coil and a magnetic field is formed and the magnetic field interacts with the rotor of the motor. This action spins the rotor, which drives the appliance the motor is attached to.
Regular maintenance should be performed to maintain your shaded pole blower motor in an efficient working condition. That means it's a good idea to keep the motor free of dust and debris, and inspect for evidence of wear or damage. And, don't forget to check to see if the motor is well-oiled and the connections are all tight.
