Title: Power generator and electric washing machine
Inventor: MOROZUMI HIDEKI
IPC: H02H3/34
Filed: 1996-11-13
Abstract: PROBLEM TO BE SOLVED: To prevent breakage and damage due to burning by making an inverter stopping means stop an inverter circuit when a continuity detecting means detects wire breaking in any winding of a three-phase winding. SOLUTION: A control means 18 is provided with a continuity detecting means 23 and an inverter stopping means 25 which is operated on a signal of the continuity detecting means 23. When the connection terminal U of the first winding 14 is kept positive, the connection terminal V of the second winding 15 is kept zero, and the connection terminal W of the third winding 16 is opened by controlling an inverter 17, which constitutes a threephase winding, current is flowed through the first and the second windings 14, 15. In case of wire breaking of the first winding 14, current flowing through the three-phase winding 13 is reduced to decrease rotational speed and torque of a motor, therefore, the control means 18 controls the rotational speed with a microcomputer to increase current flowing through the second winding 15 and the third winding 16.  The continuity detecting means 23 detects the magnitude of the inputted current. If the maximum value is in excess of a prescribed value, an ON signal is sent to the inverter stopping means 25. It is thus possible to prevent breakage and damage due to burning.

Title: Method of oil supply for enclosed oil-filled electric machine
Inventor: TSUCHIYA SHINJI
IPC: H01F27/14
Filed: 1988-11-29
Abstract: PURPOSE:To suppress expansion of a radiation rib by a method wherein insulating oil of a normal temperature is supplied into a tank and, after the tank is filled, a negative pressure is provided inside the tank and then the tank is tightly sealed. CONSTITUTION:Insulating oil of a normal temperature is supplied into a tank 1 through a supply inlet 7. After the supply of the insulating oil into the tank 1 is finished, the inlet 7 and a valve 9 are closed to seal the tank 1 tightly. A oil drain cook 11 provided on the lower part of the tank 1 is opened a little to discharge the insulating oil by a head pressure and then the cock 11 is closed to seal the tank 1 tightly. As a negative pressure is provided in the tank 1 with this process, even if the temperature of the insulating oil is elevated by the temperature rise of a transformer main part 5, the expansion of a radiation rib 4 caused by the temperature rise of the insulating oil is absorbed by the negative pressure. Therefore, it is not necessary to reinforce the rib by increasing its thickness, so that the weight and cost of an enclosed oil-filled electric machine can be reduced.
