Abstract
An electronically commutated motor assembly permits a user to select discrete operating speed options to operate an electronically commutated motor. The assembly includes a motor, an input/output unit electrically connected to the motor, a connector and board and a microprocessor. The connector and board includes an electrically erasable programmable read-only memory (EEPROM), a plurality of low voltage signal connections for programming the EEPROM, and a plurality of speed signal connections for selecting an operating speed for the electronically commutated motor. The low voltage signal connections permit the EEPROM to be programmed with speed tables containing schedules of operating speeds.
