Notes on motors 关于电机的笔记

DC motor - 直流电机

H-bridge

  • An H bridge is an electronic circuit that enables a voltage to be applied across a load in either direction. These circuits are often used in robotics and other applications to allow DC motors to run forwards or backwards From Wiki
  • H桥(H-Bridge), 即全桥(因外形与H相似故得名),是一个典型的直流电机控制电路,因为它的电路形状酷似字母H,故得名与“H桥”。4个三极管组成H的4条垂直腿,而电机就是H中的横杠。来源于百度

Servo Motor 伺服电机

  • A servomotor is a rotary actuator or linear actuator that allows for precise control of angular or linear position, velocity and acceleration.wiki
  • 伺服电机可使控制速度,位置精度非常准确,可以将电压信号转化为转矩和转速以驱动控制对象。百度

Stepper Motor 步进电机

  • A stepper motor or step motor or stepping motor is a brushless DC electric motor that divides a full rotation into a number of equal steps. Wiki
  • 步进电机又称为脉冲电机,基于最基本的电磁铁原理,它是一种可以自由回转的电磁铁,其动作原理是依靠气隙磁导的变化来产生电磁转矩。Baidu

步进电机与伺服电机

步进电机和私服电机都可以控制转动的角度,私服电机更加精确一些,常用于精密机床。
大部分3D打印机都采用步进电机。

Brushed DC motor 有刷电机

  • A brushed DC motor is an internally commutated electric motor designed to be run from a direct current power source.wiki
  • 有刷电机是内含电刷装置的将电能转换成机械能(电动机)或将机械能转换成电能(发电机)的旋转电机baidu

Brushless DC motor (BLDC) 无刷电机

  • Brushless DC electric motor (BLDC motors, BL motors) also known as electronically commutated motors (ECMs, EC motors) are synchronous motors that are powered by a DC electric source via an integrated inverter/switching power supply, which produces an AC electric signal to drive the motor.wiki
  • 无刷直流电动机是采用半导体开关器件来实现电子换向的,即用电子开关器件代替传统的接触式换向器和电刷。baidu

AC Motor 交流电机

  • An AC motor is an electric motor driven by an alternating current (AC).wiki
  • “交流电机”:是用于实现机械能和交流电能相互转换的机械。由于交流电力系统的巨大发展,交流电机已成为最常用的电机。交流电机与直流电机相比,由于没有换向器(见直流电机的换向),因此结构简单,制造方便,比较牢固,容易做成高转速、高电压、大电流、大容量的电机。baidu
