1. An electrical appliance, the electrical appliance comprising:
a motor assembly comprising at least one electric motor;
a filter network, the filter network comprising an electrical resistance component and an electrical capacitance component, wherein at least one of the electrical resistance component or the electrical capacitance component is located within the motor assembly; and
a controller electrically coupled to the motor assembly and the filter network, the controller comprising
one or more processors; and
a memory comprising instructions that, when executed by the one or more processors, cause the one or more processors to perform a process, the process comprising:
providing an input signal to the filter network;
receiving an output signal from the filter network, the output signal being filtered by the filter network;
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.
