摘要： A cooling device for an electric motor, comprising a cover which has a cylindrical-shaped main part which can house the electric motor, and a fan motor which is attached to the main part so as to blow air to the inside of the main part. The cover further has an abutting part which protrudes from an inside periphery of the main part and can abut against the electric motor. The abutting part forms a gap for blowing air between the main part and the electric motor.

摘要： A feed axis motor includes a front-side housing fixed to an end face of a stator core. The stator core is formed of a material with iron as a main component. The front-side housing is formed of a material with aluminum as a main component. The stator core and the front-side housing are coupled with each other at a welding mark generated by laser welding. The welding mark extends in a circumferential direction so as to cover a line of contact between the stator core and the front-side housing. The welding mark seals the boundary portion between the stator core and the front-side housing.

摘要： A motor cooling fan unit comprises a tubular cover capable of surrounding a motor and a fan provided to blow air toward the interior of the cover. The motor cooling fan unit is configured to cause air blown from the fan to pass through a flow path between the motor and the cover. The cover comprises an exhaust part provided at a downstream area of the flow path. The exhaust part comprises: an open part for making the flow path communicate with the outside; and an exhaust adjusting member provided for the open part and movable between a shield position at which the exhaust adjusting member covers the open part and an open position at which the exhaust adjusting member opens the open part. The amount of movement of the exhaust adjusting member is adjusted to allow adjustment of the amount of the air in the flow path to be exhausted through the open part and a direction of the exhaust, or adjustment of the amount of the air to be exhausted or a direction of the exhaust.
