    • PROBLEM TO BE SOLVED: To provide a motor with a brake, capable of stopping a rotor at a predetermined position while being positioned with high accuracy.
      SOLUTION: The motor with a brake, capable of directly transmitting rotation force to a rotor 4 to rotate the rotor in a specified direction, is equipped with a brake mechanism for stopping the rotor while being positioned at a specified position relative to stators 2a, 2b after the rotation of the rotor is braked. The brake mechanism is provided with a thin plate like disk plate 10 fixed to the rotor and braking members 12, 14 disposed on the disk plate so as to face each other in a press-contact manner, wherein one braking member 12 is fixed to the upper stator 2b, while the other braking member 14 is fixed to a piston 16. In this case, when hydraulic pressure acts on the piston, a support member 18 supporting the piston is deformed elastically, thereby the piston, and one braking member are move toward the other braking member.

    • 要解决的问题:为了提供具有制动器的电动机,能够在高精度定位的同时将转子停止在预定位置。 解决方案:具有制动器的电动机能够直接将转动力传递给转子4以使转子沿指定方向旋转,该制动机构具有用于在转子定位在相对于定子的指定位置时停止转子的制动机构 2a,2b转子转动后制动。 制动机构设置有固定到转子的薄板状盘状盘10和设置在盘形板上的制动构件12,14,以便以压接方式彼此面对,其中一个制动构件12固定到 上定子2b,而另一个制动构件14固定在活塞16上。在这种情况下,当液压作用在活塞上时,支撑活塞的支撑构件18弹性变形,从而活塞和一个制动构件移动 朝向另一个制动部件。 版权所有(C)2007,JPO&INPIT
