What are the reason for motor overload in belt drive air compressor?

Motor overload in belt drive air compressors can occur due to several reasons, including excessive load demands on the compressor that exceed its rated capacity, improper belt tension causing slippage or increased friction, and mechanical issues such as worn bearings or misalignment. Additionally, insufficient lubrication can lead to increased resistance, while environmental factors like high ambient temperatures can also contribute to overheating. Regular maintenance and proper operation can help prevent these issues.
