Nidec/Emerson 1/2-1/5 HP 70C Motor 5465H

The Nidec/Emerson 5465H is a multi-horsepower motor covering 1/5 to 1/2 horsepower with a 70 degree Celsius ambient rating, for fan and blower applications in HVAC equipment.

The 70 degree Celsius ambient rating is the specification that distinguishes this motor and it is worth understanding. It states the maximum surrounding air temperature in which the motor may operate continuously while keeping its winding temperature within the insulation system's limit.

Seventy degrees is a high figure, well above what a motor in a ventilated indoor position would ever see, and it identifies the motor as suitable for positions where the surrounding air is genuinely hot: inside condensing unit electrical compartments, in rooftop equipment exposed to summer sun, and in equipment where the motor sits downstream of a heat source.

Substituting a motor with a lower ambient rating into such a position produces early failure, and the failure will look like a defective part rather than a specification error.

The multi-horsepower winding covers several OEM ratings by tap selection.

Confirm horsepower range, RPM, voltage, rotation, frame diameter, shaft dimensions, mounting arrangement, ambient rating, and capacitor value before ordering.
