Abstract: A motor controller configured to control different types of electronically commutated motors (ECMs) includes a range of different rotor orientation signal inputs to accommodate differences between ECM motor types. The motor controller includes a control unit that receives motor operation commands and controls operation of the ECM in accordance with the motor operation commands. The control unit receives and stores data designating ECM type and estimates rotor position based on the designated ECM type.
