1. A motor comprising:
a stator including a plurality of windings that form coils and are connected together at a neutral point;
a switching circuit that generates a rotating magnetic field around the stator by switching of a power supply to the plurality of windings;
a rotor that rotates in response to the rotating magnetic field generated around the stator;
a resistor for current detection that detects a current in the switching circuit and that is disposed between the switching circuit and a grounding point; and
a filter element that reduces a fluctuation in potential at the neutral point, the filter element being disposed between the neutral point and the resistor for current detection and being grounded at the grounding point via the resistor for current detection.
