Abstract
Systems and methods for identifying a motor coupled to an electrical appliance are disclosed herein. The electrical appliance can include a motor assembly comprising at least one electric motor and a filter network including an electrical resistance component and an electrical capacitance component. The electrical appliance can also include a controller electrically coupled to the motor assembly and the filter network, the controller comprising one or more processors and a memory comprising instructions for performing a process. The process can include providing an input signal to the filter network and receiving an output signal from the filter network, the output signal being filtered by the filter network. The process can also include identifying a filter characteristic of the filter network based on the output signal and identifying a type of the electric motor based on the identified filter characteristic.
