    • PROBLEM TO BE SOLVED: To optimize performance of a brake assembly and to increase total efficiency. SOLUTION: An electromagnetic braking system and method is provided for selectively braking a motor using an electromagnetic brake having an electromagnet, a permanent magnet, a rotor assembly, and a brake pad. The brake assembly applies when the electromagnet is de-energized and releases when the electromagnet is energized. When applied, the permanent magnet moves the brake pad into frictional engagement with a housing, and when released, the electromagnet cancels the flux of the permanent magnet to allow a leaf spring to move the brake pad away from the housing. A controller has a DC/DC converter for converting a main bus voltage V M to a lower braking voltage based on certain parameters. The converter utilizes pulse-width modulation (PWM) to regulate the braking voltage. A calibrated gap is defined between the brake pad and permanent magnet when the brake assembly is released, and may be dynamically modified via the controller. COPYRIGHT: (C)2011,JPO&INPIT
    • 要解决的问题:优化制动组件的性能并提高总效率。 解决方案:提供一种电磁制动系统和方法,用于使用具有电磁体,永磁体,转子组件和制动衬块的电磁制动器选择性地制动电动机。 当电磁铁断电时,制动组件适用,当电磁铁通电时,制动器组件释放。 当施加时,永磁体将制动衬块移动到与壳体摩擦接合,并且当释放时,电磁体抵消永磁体的通量,以允许板簧将制动片从壳体移开。 控制器具有DC / DC转换器,用于根据某些参数将主母线电压V SB> M 转换成较低的制动电压。 该转换器利用脉宽调制(PWM)来调节制动电压。 当制动组件被释放时,在制动衬块和永磁体之间限定校准的间隙,并且可以通过控制器动态地修改。 版权所有(C)2011,JPO&INPIT
