軸駆動モータの冷却装置。 In a main shaft drive motor in which a rotor is inserted into the tapered outer diameter of the rear end of the main shaft via a tapered sleeve, and a stator corresponding to the rotor is fixed to a housing, air is supplied to the side of the rotor in the direction away from the rotor. In addition to providing moving fins,
A cooling passage is formed in the inner circumferential portion of the rotor and opens at a location where negative pressure is created when the fins rotate, and the other end of the cooling passage is communicated with a location where negative pressure is not created when the fins rotate. A cooling device for a spindle drive motor, characterized by:
