前言使用逻辑控制电路细分既定步进电机的步距,可以改善步进电机在低速运行时的速度平稳性。在步进电机本身精度较高和摩擦负载较小的情况下,还可以实现细步距的精确控制。一、细分控制原理步进电机的步距角由下式表示国产的三相步进电机转子大多为40个齿,如常州电讯电机厂出产的BF 184075型和北京微电机厂出产的SB3C-3B-500型的转子均为40个齿,其0=360°/3×40=30°。
Preface The use of logic control circuit subdivides the steps of a given stepper motor to improve the speed stability of the stepper motor at low speeds. In the stepping motor itself, high precision and friction load is small, you can also achieve precise control of fine step. First, the subdivision control principle Stepping motor step angle by the following expression domestic three-phase stepper motor rotor are mostly 40 teeth, such as the Changzhou Telecom Motor Factory produced BF 184075 and Beijing Micro Motor Factory produced SB3C- All 3B-500 rotors are 40 teeth, with 0 = 360 ° / 3 × 40 = 30 °.
