基于Atmega64的直流电动机软起动器设计

摘要

直流电动机是重要的生产设备，起动是影响其寿命的关键因素。以蓄电池系统供电的直流电动机为研究对象。设计一种靠单片机控制，以IGBT为功率开关元件，采用PWM斩波降压的新型软起动器。相比传统的机械式起动器，它能实现连续无级的调节电动机起动，冲击转矩和冲击电流小，起动重复性好。%Direct-current motor is important production equipment while its starting has a lot to do with its life span. A novel soft starter is designed controlled by a single chip and with IGBT as the power switch element and adopting PWM chopped wave to reduce pressure. Compared with traditional starters, the newly designed soft starter enjoys many advantages and sound performance.
