摘要:在现代电子产品中,自动控制系统,电子仪器设备、家用电器、电子玩具等等方面,直流电机都得到了广泛的应用。大家熟悉的录音机、电唱机、录相机、电子计算机等,都不能缺少直流电机。所以直流电机的控制是一门很实用的技术。直流电机,大体上可分为3类:几相绕组的步进电机、永磁式换流器直流电机、伺服电机、
直流电机具有良好的启动性能和调速特性,它的特点是启动转矩大,最大转矩大,能在宽广的范围内平滑、经济地调速,转速控制容易,调速后效率很高。与交流调速相比,直流电机结构复杂,生产成本高,维护工作量大。适用范围:直流调速器在数控机床、造纸印刷、纺织印染、光缆线缆设备、包装机械、电工机械、食品加工机械、橡胶机械、生物设备、印制电路板设备、实验设备、焊接切割、轻工机械、物流输送设备、机车车辆、医疗设备、通讯设备、雷达设备、卫星地面接受系统等行业广泛应用。
关键词:现代电子产品直流电机广泛应用
Abstract: In modern electronics, automatic control systems, electronic equipment, household appliances, electronic toys, etc., DC have been widely used. The familiar tape recorder, record player, VCRs, computer, etc., can not do without DC. Therefore, DC motor control is a very practical technology. DC motor, can be divided into three categories: a few windings of the stepper motors, permanent DC motor inverter, servo motor,
DC motor has a good start-up performance and speed characteristics, it is characterized by a large starting torque, maximum torque, in a wide range of smooth, economical speed, speed control is easy, after a very efficient speed. Compared with AC variable speed, DC plex structure, high production costs, maintenance workload.
Application: DC converter C machine tools, paper and printing, textile printing and dyeing, fiber cable equipment, packaging machinery, electrical machinery, food processing machinery, rubber machinery, bio-devices, printed circuit board equipment, laboratory equipment, welding and cutting , light industry, logistics and transport equipment, otives, medical equipment, communications equipment, radar equipment, satellite ground receiving system, widely used in industry.
Keywords: modern electronic products widely used in DC motor
