Abstract
An HVAC control system, associated brushless direct current motor, and methods of operation are disclosed. One such control system includes a brushless direct current motor and an optically-isolated interface exposing control access to the brushless direct current motor. The system includes a first programmable controller electrically connected to the brushless direct current motor, the programmable controller configured to receive a control signal via the optically-isolated interface, and a second programmable controller providing the control signal to the optically-isolated interface.
