微型直流电机检测系统的设计与实现

随着现代汽车的不断发展，汽车上大量使用了微型直流电机来驱动天窗、控制风门。车用直流电机结构特殊．在实际应用中对带负载情况下的相电流、运转角度与反馈电压的线性度等问题具有严格要求。通过硬件电路的设计、软件代码的编写实现了直流电机综合性能测试系统，该系统结构简单、性能稳定，能够满足企业对微型直流电机自动化检测的需求。系统运用磁粉制动器、扭矩传感器来模拟负载的加载和检测，此方法能够应用到其他需要模拟负载的系统中，具有良好的推广应用价值。

Design and Implementation of Micro-motor Detection System

As modem vehicles are improving continually, more and more miniature direct current motors are used in vehicles to drive skylights and control dampers. The DC motors in vehicles have special structure. It has strict requirements for phase current, operation angle, linearity of feedback voltage with load in practical applications. This paper designs an integrated performance test system of the direct current motor through hardware and software code. The system has simple structure and stable performance. And it can meet automation detection requirements of factory for miniature direct current motors. System uses magnetic brakes andtorque sensors to simulate the loading and detectionof the load. This method can be applied to other systems which needs simulating load, and it has good value and prospect of popularizing application.
