Elegantly simple low-cost retrofit method and system for replacing a constant torque electronically commutated motor with a fix-speed permanent split capacitor motor
A system and method are provided to allow the replacement of a costly electrically commutated blower or fan motor with a less efficient motor such as a permanent split capacitor motor operating at a predetermined speed, without regard to the specific electrically commutated motor command signals or programming being used by the original equipment manufacturer. A retrofittable control board is employed to activate the replacement motor by energizing the replacement blower motor when an electrically commutated blower motor command signal is observed on any one of the signal lines which are continuously monitored simultaneously.
