Abstract:
Provided is a motor that reduces the chances of powder dust entering the gap between a rotor and a stator. A motor 1 includes a stator 3, a rotor 2, and a cover 51. The rotor 2 is disposed inside the stator 3 with a gap 6 left with respect to the stator 3. The rotor 2 is provided to be rotatable with respect to the stator 3. The stator 3 includes a plurality of coils 31, a plurality of teeth 32, and a coupling portion 33. Around the plurality of teeth 32, the plurality of coils 31 are respectively arranged via an insulator 5. The coupling portion 33 is located closer to the rotor 2 than the plurality of coils 31. The coupling portion 33 couples at least some adjacent ones of the plurality of teeth 32. The cover 51 is formed mechanically integrally with the insulator 5. The cover 51 is disposed to face at least a space 35 inside the coupling portion 33 along a rotational axis X of the rotor 2. The cover 51 closes the gap 6.
