Title:
INDUCTION MOTOR
Document Type and Number:
Japanese Patent JPS6096156
Kind Code:
A
Abstract:
PURPOSE:To effectively cool a winding and bearings by forming a groove on the surface of a stator, and forming a hole which communicates with the groove on a rotor opposed to the stator. CONSTITUTION:When a washing side rotor 11 rotates at washing time, air flows by a cooling fin 20 toward the outer periphery of the rotor 11. In this case, wind air flows along radial grooves 14b formed on the rotor 11 and the stator through a hole 15b formed at the rotor 11 to cool the heated stator core 12 and the entire stator as well as bearings 17, 18 secured to the stator. Air flows through the hole 15a formed at the dehydrating side rotor 9 and the groove 14a of the stator by the rotation of the rotor 9 even at the dehydrating time to cool the stator.
