Title:
ROTARY ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JPS5937860
Kind Code:
A
Abstract:
PURPOSE:To improve the magnetic characteristic and heat sink property of a rotary electric machine, to enhance the production efficiency and to reduce the size of the machine by forming slits on the outer periphery of a stator core which is welded fixedly to the bottom of the wavy heat sink fin of a casing. CONSTITUTION:Slits 5 are formed at both sides of the welded parts 8 of wavy heat sink fin 1 on the outer periphery of a stator core 3. The heat transfer at the welding time is reduced by the slits 5, thereby preventing the thermal deformation and magnetic characteristic at the welding time from decreasing. The loss heats generated from a rotor, stator core 3 and stator coil at the operating time are transmitted to the fins 2, and dissipated to the outer air by forcible ventilation air.
