摘要： An induction motor which is free from an induced voltage and has high power characteristics over a wide range. The winding of each phase comprises a plurality of partial windings having identical number of turns. When a low speed high torque rotation is necessary, the partial windings of each phase are connected in series in a Y-connection as shown in Fig. 2a, when an intermediate and low speed rotation is necessary, the partial windings of each phase are connected in series in a DELTA -connection as shown in Fig. 2b. In the case of an intermediate-high rotation, the partial windings are connected in parallel in a Y-connection as shown in Fig. 2c. In the case of a high rotation, the partial windings are connected in parallel in a DELTA -connection as shown in Fig. 2d. Since all the windings of the phases are used and the numbers of turns of the windings are reduced from the low speed rotation to the high speed rotation in order, an unused winding does not exist, an induced voltage is not generated, the drop of the power at the time of the changeover of the winding pattern can be covered, and high power characteristics can be obtained over a wide range.

摘要： A reactor (32) and a switch (35) are interposed in parallel between U-phase, V-phase and W-phase on a power source side (31) and U, V and W terminals on a motor side (33). A changeover switch (37) is interposed between Z, X and Y terminals on the motor side (33) and the U, V and W terminals on the motor side (33). When the switch (35) is set to OFF, the changeover switch (37) is set to ON, and the switch (35) is set up so as to interconnect Z, X and Y terminals, windings of the motor are set up in the form of Y-connection, so that the motor and a power source are connected directly to each other. On the other hand, when the changeover switch (37) is switched over to OFF, and the switch (35) is set up so as to interconnect Z, X and Y terminals to the U, V and W terminals, the windings of the motor are set up in the form of DELTA -connection, so that the motor and the power source are connected together through the reactor (32).

摘要： A motor (33) having terminals U, V and W connected through reactors (32) to the corresponding phases of a power supply (31), each reactor (32) being connected in parallel with a switch (35). The motor is further provided with terminals Z, X and Y connected with its terminals U, V and W through switches (37). When the switches (37) are closed and the switches (35) are set to interconnect the terminals Z, X and Y, the winding of the motor becomes Y-connection and the motor is directly connected to the power source. On the other hand, when the switches (37) are opened and the switches (35) are set to connect the terminals Z, X and Y to the terminals U, V and W, the winding of the motor becomes delta-connection and the motor is connected to the power source through the reactor (32).

摘要： PROBLEM TO BE SOLVED: To provide a squirrel-cage rotor for an induction motor that has a configuration that eliminates the need for a process of arranging brazing filler and facilitates bonding of bars and an end ring so as to reduce man-hours in the bonding by brazing, and to provide a method for manufacturing the squirrel-cage rotor.SOLUTION: Prior to a process in which a rotor core 10 is assembled, a silver plated layer 24 is formed on at least either of an end ring 14 and conductor bars 20. The rotor 10 is heated to a temperature that is equal to or higher than a melting point of the silver plated layer 24 so as to melt the silver plated layer 24. The melted silver plating serves as brazing filler and bonds the end ring 14 and the conductor bars 20 together.
