Features

  • These motors have dripproof enclosures to permit the flow of external air over and around the motor windings to keep it cool during the operation.
  • They feature rolled steel construction for enhanced rigidity and ball bearings for smooth movement of internal parts.
  • Models, such as 5KH36KN112X H287 HVAC Motor offers thermal protection, detecting overheating conditions and disconnect the motor power.
  • The split-phase motor design of these motors delivers speeds ranging from 850 to 1725 rpm and can be mounted in either horizontal / vertical orientation.

Standards and Approvals

  • UL
  • CSA
  • CE

Frequently Asked Questions

How to maintain the motor?

In order to keep the motor running smoothly, use permanently lubricated sealed bearings to protect against contamination and friction loss.

What is the purpose of continuous duty motors?

Continuous duty (or induction) motors are rated for continuous operation within the stipulated temperature range, wherein, the motor runs with a constant load for a long duration to reach thermal equilibrium.

What are single-phase motors?

Single-phase motors use a capacitor to provide additional power during motor startup. These motors are ideal for equipment and machines that are smaller in size and need lower horsepower.
