Document Type and Number:
Japanese Patent JP2019198205
Kind Code:
A
Abstract:
To make it possible to prevent weight balance of an armature from deteriorating even if a double flyer method is adopted to facilitate coil winding work and to provide an electric motor capable of reducing a value of a current flowing in a pressure equalizing line.SOLUTION: The electric motor includes: a first coil 71 formed by arranging first small coils 71U to 71W and second small coils 72U to 73W on separate teeth 50; and a second coil 72 formed by arranging third small coils 73U to 73W and fourth small coils 74U to 74W on the separate teeth 50. The first small coils 71U to 71W and the fourth small coils 74U to 74W are arranged on one tooth 50. The second small coil 72U to 73W and the third small coil 73U to 73W are arranged on the other tooth 50.
