Abstract
A motor includes a stator and a rotor having drive permanent magnets and a rotary shaft. The stator supports a core with coils wound thereon and includes a base plate. The base plate is formed with a resin, and is composed of a core supporting section that supports the core, a shaft supporting section that rotatably supports the rotary shaft, and attachment sections for attaching the motor to an apparatus. The core supporting section, the shaft supporting section and the attachment sections of the base plate are formed in one piece.
Claims28
A motor comprising:
- a rotor having drive permanent magnets:
- and
- a stator having a core with coils wound thereon and a base plate with a core-opposing surface and at least one attachment section, wherein the base plate is formed with a resin, and the base plate and the core are fixed to each other through fixing element.
A motor comprising:
- a core having a plurality of salient poles that are arranged in a circumferential direction and protrude in a radial direction and a coil wound on each of the salient poles;
- a base plate having a core-opposing surface that opposes the core and at least one attachment section, wherein the base plate is formed with a resin and has a reinforcement section that protrudes towards the core.
A motor comprising:
- a rotor having drive permanent magnets:
- and
- a stator having a core with coils wound thereon and a base plate having attachment sections for attaching the motor,
- wherein the base plate is made of resin and has grooves that guide lead wires to supply power to the coils, from an outer side towards an inner side of the base plate to the vicinity of coil terminals of the coils.
A motor comprising:
- a rotor having drive permanent magnets and a rotary shaft that rotates in a unitary fashion with the rotor:
- a core with coils wound thereon;
- and
- a stator having a resin base plate comprising a core supporting section that supports the core, a shaft supporting section that rotatably supports the rotary shaft, and attachment sections that attach the motor to an apparatus.
