There are a few types of motors. Only a few manufacturers in the industry carry the top-of-the-line motors and DC Motors. While all the rest have direct drive motors.
Casablanca XLP-2000/XLP Plus - The leading motor type in the industry alongside the Emerson K55XL and the Fanimation FK2100. This motor type is distinguished with its Polyurethane Flywheel technology; which gives the fan blades a sense of ‘float’. With exceptional performance and noise-free operation for the life of the fan.
Emerson K55XL - In 1986 Emerson introduced the top-of-the-line K55 motor with the Silent Rubber Hub becoming the industry standard for quiet and high performance motors.
Fanimation FK2100 - Following the Rubber Flywheel technology, Fanimation designed the FK2100 for optimal performance and lifetime guarantee.
DC Motor - The motor of the new era. This motor requires less electrical current by utilizing an internal array of magnets of opposing polarity. This magnetic field requires much less electrical energy to create the torque required to rotate the motor’s rotor. This motor type is virtually silent, while generating more power / torque than conventional ceiling fan motors and consuming less than 70% of the power.
Direct Drive (Motor Sizes)
There is a few types of direct drive motors. The type of motor directly correlates with the size of the motors diameter. Direct Drive motors are the most common types of motors in ceiling fans. Large powerful motors consist typically of 200+ mm in diameter. Large motors consist typically of 188+ mm in diameter. Medium motors consist typically of 153+ mm in diameter, while anything below 153mm is considered a small motor.
Fan Operation: Which direction settings should I use?
Reverse during the cold season, and forward during the hot season. To know your fan is spinning it Reverse, it should be spinning clockwise. To know if your fan is spinning forward, it should be spinning counter-clockwise.
My fan is making a clicking sound. How do I make it stop?
Check to see if a screw or nut is loose. Check the fan pole mounts to make sure it’s secured. Check the mounting bracket located under the canopy to make sure it’s secured to the junction box and ceiling. Make sure that all screwed and nuts are tightened.
My ceiling fan is humming and the motor is not spinning. What's the problem?
In this case, the capacitor in your ceiling fan has gone bad. The fact that it is making a humming noise is the fan is still receiving power but does not have the ability to spin with a bad capacitor. These parts are available for replacement, but any uncertified ceiling fan technician that opens the motor housing of your fan will cause the fan to void warranty. Another cause for this to happen is the control system for your fan may be the wrong type of system, thus causing the humming noise without the motor to spin.
