摘要
利用单片机开发了电流、电压同步高速采集设备。在不采用转速转矩传感器的情况下,提出了一种基于频谱分析的电机转速识别算法和基于气隙转矩法的电机转矩识别算法。开发了便携式电机能效测试设备,可在现场不拆卸电机的情况下完成电机能效测试,方便快捷。使用该设备进行电机能效测试,并与电机综合性能测试系统测试结果进行对比,吻合度较高。该便携式电机能效测试设备可满足工程测试实际需求。
A high-speed current and voltage synchronous acquisition device is developed based on single-chip computer. Without the use of speed and torque sensor, a motor speed identification algorithm based on frequency spectrum analysis and a motor torque identification algorithm based on air gap torque method are proposed. The portable motor energy efficiency test equipment is developed, which can complete the motor energy efficiency test without dismantling the motor on site. This tester can realize convenient and fast test. It is used to test a motor and the test results are compared with those obtained from an integrated motor performance testing system. The good agreement between the results verifies the applicability of the portable tester. It can meet the practical engineering test requirements.
