発明の名称 (英語) MOTOR NEW
発明の概要(英語) Provided is a motor having a rotor that has a rotating shaft extending in one direction, a housing that accommodates at least a portion of the rotor, and a stator that is accommodated in the housing. The rotor has a cylindrical air-cooling unit at least at one end side of the rotating shaft. The air cooling unit has a through-hole provided in a cylindrical shape that passes through the body of the air-cooling unit. The rotating-shaft-direction end part of the air cooling unit is exposed and open at the outside of the housing. A first through hole opens to the inside of the housing, and either the rotor or the stator has a plurality of coils arrayed in the circumferential direction of the rotating shaft. The housing and/or the rotor has a cooling hole that communicates with the interior of the housing, the cooling hole being located at the opposite side from the air cooling unit with respect to the coils.
従来技術、競合技術の概要(英語) BACKGROUND ART
Of the working population in recent years with the increase and decrease of an elderly person, worker or workers engaged in the heavy load on elders, the assist operation of the robot has been developed.In addition, in a production site, a person adjacent to the robot works, in cooperation with the introduction of so-called robot has been advanced.In such a robot, the actuator motor is used as a driving source.
Of the robot is described above, it is possible to improve feeling of use in accordance with a request such as to ensure the working space, the size of the demanded.Therefore, the motor is used as a driving source, small size and high output is demanded.
In general, the output of the motor, increases corresponding to the electric power to be supplied.On the other hand, an increase in input power to the motor, the driving of the motor heat generation is also increased.Therefore, a high output motor is used, a heat is transferred to the drive, and prevent damage is obtained.Such as a motor, the motor cooling water or cooling from the outside has a configuration has been known (see Patent Document 1).
