MOTOR DRIVEN MACHINE
Document Type and Number:
Japanese Patent JPS5921253
Kind Code:
A
Abstract:
PURPOSE:To improve the reliability of a motor driven machine by partly extending the coil of a main motor as an exciting coil for an auxiliary motor or a solenoid coil, thereby reducing the size of the auxiliary excitation element and reducing the troubles of disconnection. CONSTITUTION:The main and auxiliary coils MC, AC of a main motor 20 are extended to connected the main and auxiliary coils Mf, Af of an auxiliary motor 21 are connected in series. A starting capacitor 22 is further connected to the auxiliary coil. Main and auxiliary motors 20, 21 are simultaneously started and stopped by one capacitor, the same current as the motor 20 flows in the motor 21, and a small amount of a thick coil may be wound. Thus, the entire size can be reduced, the troubles of disconnection are reduced to improve the reliability. This is adapted for a room air conditioner in which a plurality of motors are simultaneously operated.
