Filed: 1992-07-20
Abstract: PURPOSE:To move the noise of an audible range out of the range and to reduce the noise by providing a circuit for dividing an ON period of a PWM wave signal. CONSTITUTION:A circuit for dividing an ON period of a PWM wave signal is provided between a PWM circuit 48 and a driver 60. A PWM waveform (1) from the circuit 48 is input to an AND gate 12 together with an output (2) of a shift register 11. If no input of the wave (1) exists at the register 11, the output (2) of the register 11 is ON, and hence if the wave (1) is ON, an output (3) becomes ON. If the ON is continued for a predetermined period, QA-QD of the register 11 become ON, and hence the output (2) of the register 11 is turned OFF, and the output (3) is operated by an AND of the waveform (1) and the output (2) of the register by the AND gate 12, and hence the output (3) becomes OFF. Thus, the signal of the output (3) is obtained. That is, the noise is moved out of an audible range to be reduced.

Title: Squirrel-cage rotor of induction motor
Inventor: SHIMIZU EIJI
IPC: H02K15/12
Filed: 1999-07-07
Abstract: PROBLEM TO BE SOLVED: To improve penetration of an insulating material and favorably form an insulating material layer by impregnating the gap between a slot portion and a conductor with the insulating material, and providing insulation between them. SOLUTION: If a stress A, such as torque or centrifugal force, is exerted on a conductor 3, for example, when an induction motor is started or running, the conductor 3 with the stress A exerted thereon is bent because of the gap between a slot portion 2 and the conductor 3. When by repeating this, the conductor 3 develops fatigue failure. If an insulating layer 7 is placed between the slot portion 2 and the conductor 3, the conductor 3 is prevented from moving even under the stress A by the insulating material layer, so that fatigue failure of the conductor 3 is prevented from occurring. In addition, since the conductor 3 is not brought into direct contact with the inner face of the slot portion 2 because of the insulating material layer, stray load losses are substantially eliminated. Therefore, a durable, high-quality squirrel-cage rotor of an induction motor is obtained.
