The motor fault diagnosis instrument can automatically draw diagnostic conclusions and maintenance suggestions

　　Motor fault diagnosis deviceWidely used for predictive maintenance of electrical equipment such as induction motors, VFD motors, DC motors, synchronous motors, generators, and transformers in factories. The user first uses the DMT301 motor fault detector to detect and collect the current and/or voltage signals of the motor in the MCC, and then uploads the data to the PC through the USB interface. EMA diagnostic software is used for data storage, spectrum processing, and feature analysis to obtain automatic diagnostic conclusions and maintenance recommendations. It can also be used to view and verify the characteristics of various faults using the reports and graph tools provided by the software.

The motor fault diagnosis instrument EMA software provides a systematic and comprehensive diagnosis of electric motors, covering not only the rotor, stator, and air gap of the motor body, but also power quality, harmonics, power, connections, three-phase balance, as well as analysis of bearings and driven machinery such as fans, pumps, belts, gearboxes, and reciprocating machines.Motor fault diagnosis deviceThese analysis and judgment rules are based on over 30 years of technological development, electrical standards, experience, and extensive validation of measured data, and have * technical advantages. The DMT301 hardware is designed based on the development of modern electronic technology, using ARM microprocessors and 24 bit analog-to-digital conversion to ensure sufficient high precision, high resolution, and dynamic range required for signal analysis.

The DMT301 motor fault diagnosis instrument can synchronously detect single-phase current and voltage signals, and can also perform three-phase testing step by step in sequence. Therefore,Motor fault diagnosis deviceThe on-site testing requires fewer current sensors and voltage connection accessories, making it simple and lightweight. If the high-voltage motor in the factory is equipped with MTP-H/L motor test interface module, DMT301 can be directly connected to the test interface using a test cable, which can achieve safer and more effective data acquisition.

Detailed introduction of motor fault diagnosis instrument:

△ The scope of application is expanded to larger capacity transformers, generators, and motors;

Fully charged, can be used continuously for 10 hours;

Display real-time impedance value, phase angle, and percentage difference of three-phase impedance;

The testing frequency can be freely selected (30, 50, 60, 100, 200, 400, 800 Hz);

△ Self check test can determine whether the tested motor is affected by external electromagnetic interference, which affects the test results;

The insulation test can be conducted in two levels, 500V and 1000V, with readings up to 500M Ω;

△Motor fault diagnosis deviceThe new rotor testing function is simpler and more intuitive, quickly diagnosing casting defects, eccentricity, and bar breakage faults.
