Engineering Contradiction Analysis
1Productivity
If traditional detection methods are used for permanent magnet synchronous motors, then the detection process is simple, but the detection efficiency is low and motor loss cannot be effectively tested
Solution Approach 1:
The detection system is divided into multiple functional modules: power supply module, motor module, measurement module, and control module. Each module performs a specific function, allowing parallel data acquisition from multiple parameters simultaneously, thereby improving detection efficiency without overwhelming system complexity
Solution Approach 2:
A data synchronous acquisition module is introduced as an intermediary component that coordinates data collection from multiple sensors and instruments. This mediator synchronizes the acquisition of electrical parameters, mechanical parameters, and temperature data, enabling efficient comprehensive detection while managing system complexity through centralized control
2Measurement precision
If comprehensive motor parameter testing is performed to accurately assess energy efficiency, then detection accuracy is improved, but detection time and energy consumption increase
Solution Approach 1:
The system performs preliminary data acquisition setup and synchronization before actual motor testing begins. Measurement instruments are pre-configured and calibrated, and data acquisition channels are established in advance, allowing immediate comprehensive data collection when testing starts, thus reducing overall detection time while maintaining accuracy
Solution Approach 2:
The detection system continuously acquires multiple parameters simultaneously throughout the motor operation cycle rather than sequentially measuring each parameter. This continuous parallel measurement approach maintains high detection accuracy while minimizing total detection time by eliminating idle measurement transitions
3Measurement precision
If multiple measurement instruments are used to acquire comprehensive motor data, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
Multiple measurement instruments including power analyzers, torque sensors, and temperature sensors are merged into a unified detection system controlled by a central control module. This integration allows simultaneous multi-parameter measurement while managing complexity through centralized coordination and unified data processing
Solution Approach 2:
The measurement system is designed with multi-functional instruments that can measure multiple parameters. The data synchronous acquisition module serves universal functions of coordinating different measurement channels, and the control module manages both power supply and data acquisition, reducing the need for separate dedicated devices for each function
