BLOWER MOTOR FOR HVAC SYSTEMS

摘要

A blower motor assembly having a variable speed motor that is suitable for replacing a PSC motor in a residential HVAC (heating, ventilation, and air conditioning) system. The blower motor assembly includes a variable speed motor and motor controller; a first power input for receiving a plurality of AC power signals from a control device for use in determining an operating parameter for the motor; and a second power input for receiving AC power from an AC power source for powering the motor controller even when no AC power signals are received by the first power input.

主权项

1. A method of replacing a permanent split capacitor motor with a variable speed motor assembly including a variable speed motor, the method comprising:
removing the permanent split capacitor motor; connecting speed/tap selection wires from a furnace control board to a sensing circuit of the variable speed motor assembly; and connecting an AC power line to a rectifier circuit of the variable speed motor assembly for powering the variable speed motor independently of the furnace control board.
