What type of motor mount is commonly used for fractional HP motors in central electric furnaces?

The most common type of motor mount used for fractional horsepower (HP) motors in central electric furnaces is the resilient mount. This type of mounting provides a balance between stability and vibration dampening. Resilient mounts are designed to absorb vibrations produced by the motor during operation, which is particularly important in HVAC systems where excessive vibration can lead to noise and potential damage to other components.

The resilient mounts typically use rubber or a similar material that allows for some give, thereby reducing the transmission of vibrations through the furnace structure. This dampening effect helps maintain system efficiency and extends the life of both the motor and the furnace.

In central electric furnaces, where the motor's operational characteristics can generate consistent vibration, employing a resilient mounting system enhances overall performance and comfort within the environment that the furnace serves.
