PIEZOELECTRIC MOTORSMPSCHOLARUsing the piezoelectric effect, which is a phenomenon in which certain materials generate an electric charge in response to the application of mechanical stress, piezoelectric motors are able to function appropriately. Conversely, the application of an electric field enables certain materials to alter their shape or size. Piezoelectric motors utilize this dynamic ability to generate motion. In con...

LINEAR MOTORSMPSCHOLARConventional rotary motors generate rotational motion, but linear motors produce motion in a straight line. Linear motors are a kind of electric motor that produces motion in a straight line. The same laws of electromagnetism that regulate rotary motors are responsible for this direct linear motion; nevertheless, the layout and operation of the two types of motors are fundamentally different. A li...

有刷直流电机和无刷直流电机:参数、操作和直流电机驱动器技术文章直流电机是将电能转换为机械运动的机器,它功能多样,无论是在小型家用电器还是工业机械中,都能见到它的身影。直流电机依赖电磁的相互作用工作,它简单、高效且用途广泛。 两种常见的直流电机类型包括有刷直流电机和无刷直流 (BLDC) 电机。本文将介绍与之相关的组件、操作、参数以及计算,另外还将介绍可与这些解决方案一起使用的电机驱动器。 无论是有刷还是无刷,直流电机都有一些关键参数必须检测、监控甚至计算出来,用于确定哪种电机最适合应用。 图 1 总结了电机驱动器的参数,下面将进行更详细的描述。 1. 电压:电压是施加到电机上的电势差。电机的电压非常重要,因为它决定了其他一些关键参数,如电机的速度、扭矩和输出功率(POUT)。电压越高,电机速度就越快。通过调整电压可以对电机进行控制,改变电压除了可以改变电机的速度,还可以反转电机的旋转方向。降低电压则会减慢电机速度;当电压降至零...
