Century D540 Shaded Pole Motor 1/100 Hp 115V 1550 Rpm 3.3in

Product Description

The CENTURY D540 is a shaded pole OEM replacement motor rated at 1/100 HP, designed for direct substitution in original equipment applications. Running on 115 volts at 60 Hz and 1550 RPM with a single speed, this motor features a totally enclosed air over (TEAO) enclosure, making it suited for applications where airflow over the motor provides cooling. Class B insulation keeps it durable across standard operating conditions, and thermal protection is built in to guard against overload. The 3.3-inch diameter frame fits compact installation spaces typical of small fan and blower assemblies. HVAC technicians and service pros handle this type of replacement during routine maintenance or equipment failure calls.

This motor is commonly used in residential and light commercial HVAC equipment where a small-frame shaded pole motor drives a fan or blower wheel. Its TEAO construction suits it for positions where ambient airflow is directed over the motor housing. The 1/4-inch diameter shaft with a flat, along with 12-inch leads terminated with a molded plug, simplifies drop-in replacement work. Extended studs at both the shaft end and lead end allow for straightforward mounting in original bracket configurations.
