Abstract
An electric motor includes: a ring-shaped stator attached to an inside of a tubular body part; a rotor rotatably arranged inside in a radial direction of the stator; and a tabular member attached to one end of the body part and including a power supply cable through-hole through which a power supply cable pierces, the power supply cable being pulled out from a coil included by the stator, wherein the stator and the tabular member are rotatable around a rotation center axis of the rotor, and a position of the power supply cable pulled out from the coil and a position of the power supply cable through-hole can be changed in a circumferential direction of the body part.

An electric motor comprising:
- a ring-shaped stator attached to an inside of a tubular body part;
- a rotor rotatably arranged inside in a radial direction of the stator;
- and
- a tabular member attached to one end of the body part and including a power supply cable through-hole through which a power supply cable pierces, the power supply cable being pulled out from a coil included by the stator,
- wherein the stator and the tabular member are rotatable around a rotation center axis of the rotor, and a position of the power supply cable pulled out from the coil and a position of the power supply cable through-hole can be changed in a circumferential direction of the body part.
An electric motor comprising:
- a ring-shaped stator attached to an inside of a tubular body part;
- a rotor rotatably arranged inside in a radial direction of the stator;
- a tabular member attached to one end of the body part and including a power supply cable through-hole through which a power supply cable to supply electric power to a coil attached to the stator pierces;
- and
- a terminal box which is attached to the tabular member and stores a terminal to which the power supply cable having pierced through the power supply cable through-hole is connected,
- wherein the stator and the tabular member are rotatable around a rotation center axis of the rotor, and a position of the power supply cable pulled out from the coil and a position of the power supply cable through-hole can be changed in a circumferential direction of the body part, and
- wherein in the terminal box, a power cable introduction part is arranged outside in the radial direction of the body part, a power cable to supply electric power of a power source to the coil being introduced to the terminal through the power cable introduction part.
