Title: Control system for ac electric vehicle
Inventor: UEDA YUKIO
IPC: H02P27/06
Filed: 1980-01-29
Abstract: PURPOSE: To reduce the capacity of equipment such as an inverter, a transformer and a single-phase converter by a system wherein a current limiting value is lowered to such a value as to prevent the failured commutation of the converter when line voltage is reduced to not greater than a predetermined value.  
     CONSTITUTION: An arithmetic section 13 makes a comparison and performs calculations among a notch instruction and current limiting instruction from a master controller 14, an output of a speed detecting circuit 11, an output from a current detecting section 12 and output voltage of a single-phase converter 4 via a voltage detecting section 15 so as to control output voltage and frequency of an inverter 7 and accerelate a three-phase conduction motor 8 with a predetermined current limiting value. When a detected voltage signal from the voltage detecting section 15 is lowered to not greater than a predetermined value, the current limiting value is reduced to such a value as to prevent the failured commutation. By so doing, the failured commutation of the inverter can be positively prevented beforehand.

IPC: F04C18/20
Filed: 1979-02-02
Abstract: PURPOSE: To prevent discharge pressure leakage by a method wherein a labyrinth seal is formed between the inside of a blower casing and a bearing unit, leakage pressure is reduced, and the reduced pressure is induced into the suction side of the blower casing.  
     CONSTITUTION: When a part of the pressure produced at discharge side D inside of blower casing 5 during the operation is about to leak toward motor 7 and the side of timing gear casing 9 from each shaft via bearing 6, its pressure is reduced when it passes each labyrinth seal L, and it reaches air chamber 14 provided on the rotor side of oil seal 13. Then, it is sucked into suction side S inside of blower casing 5 from connection hole 15. For this reason, it does not press oil seal 13, and at the same time, its leakage to the side of bearing 6 is prevented. Hence, no grease inside of bearing 6 is extruded to motor 7 or to the side of timing gear casing 9, and it is held inside of bearing 6.
