摘要
本文开发了一种基于数字存储式控制的交流电机软起动装置。该装置应用交流电机的降压启动原理,采用晶闸管的相控方式,利用数字存储器E2PROM为核心实现了控制系统的设计。通过控制电路部分的软硬件结合,以及主电路与控制电路的协调配和,装置实现了相应的功能,并提供给学生一个系统掌握专业知识的平台。
This paper develops a kind of soft start equipment of AC motor based on digital memory control.The equipment applies the step-down of voltage starting theory,adopts the phase control manner of thyristor and uses digital memorizer E2PROM as the core to realize the design of the control system.Through combining the software with hardware of control circuit and coordinating main circuit with control circuit,the equipment realizes the corresponding function and provides the students a platform to systematically master professional knowledge.
