基于Multisim的电机正反转控制和缺相运行仿真

Simulation of Electromotor Positive-negative Rotation Control and Phase-deficient Operation Based on Multisim

常规的电机控制实验由于实验器材和安全因素的限制,无法实现短路故障下的信息显化和故障诊断,导致实验的完整性和辩证性存在缺失。为了克服该方面的不足,在原有实物实验基础上,补充仿真内容。基于Multisim14设计了电动机正反转控制的仿真电路,增加了电机缺相运行故障的显化分析与诊断内容。经过实践证明,该设计方案可有效提升学生对理论知识的认知深度和广度,提高整体性、辩证性思维能力。

Conventional motor control experiments are unable to realize information visualization and fault diagnosis under the condition of short-circuit faults due to the limitations of experimental equipment and safety factors,resulting in the lack of integrity and dialectics of the experiment.In order to overcome the shortcomings in this aspect,the simulation content is supplemented on the basis of the original physical experiment.Based on Multisim14,the simulation circuit of Electromotor Positive-negative Rotation Control is designed,and the obvious analysis and diagnosis content of the motor's phase-deficient operation fault is added.It has proved that the design scheme can effectively enhance the depth and breadth of students'cognition of theoretical knowledge,and improve the overall and dialectical thinking ability through practice.
