Belt-System Usage and Advantages

Belt driven electric motors are in common use today. It is estimated that approximately one-third of the electric motors in commercial and industrial buildings use belt drives, including the motors in common HVAC equipment, primarily fans. Belts, along with sheaves, allow for flexibility in adjusting the positioning of the motor relative to the load, so that fan speeds can be adjusted relative to the motor speed and provide greater operating efficiency.

Operating efficiency, however, can deteriorate due to improper tension, belt wear, or misalignment. That’s why proper and routine maintenance are so critical to maximize your building’s HVAC efficiency.
