1.Description

Motor-to-motor testing primarily involves driving two identical or different types of motors together to assess their performance. This test method is mainly used to evaluate the motors' operating characteristics, efficiency, power, and performance under different loads.

2.Progress

In the driving test, one motor serves as the primary power source, while the other acts as the driven component. During the test, the motor's operating status is observed and relevant data is recorded by adjusting parameters such as motor speed and load. This data includes, but is not limited to, motor current, voltage, power factor, and temperature rise.

3.Lab Importance

Motor-to-motor testing plays a crucial role in motor product development, production, and quality control. By testing and analyzing the actual operating conditions of the motor, its stable and reliable performance can be ensured, thereby guaranteeing the normal operation of related equipment or systems. Furthermore, this test can help engineers identify potential problems and provide a reference for continuous product improvement.

1.Tested Motor（Reluctance Motor）

2. Accompany test motor（Asynchronous Motor）

First, start the test motor to the measured speed. Then, use the MC20 speed tracking function to quickly catch up with the test motor speed (before starting, ensure that the synchronous speed conversion frequency of the two motors is the same). Since the test motor is an asynchronous motor, use the slip of the test motor to reduce the speed of the test motor, thereby realizing the loading function of the test motor. If the test motor is a synchronous motor, the 0-frequency torque setting mode can be used for loading.

6.Solution Features

1. Economical and energy-saving: The system uses the MC20 common bus configuration for testing, effectively reducing power consumption during the test. The power generated by the test motor can be fed back to the DC bus of the inverter of the motor under test, thus achieving energy savings.

2. The system uses the MC20 high-performance VFD, which can quickly and stably start and stop the equipment. It features high starting torque, low impact on the power grid, and provides reliable performance, especially for long-term operation.

3.Comprehensive protection features: The MC20 VFD itself has overload, overcurrent, overvoltage, and phase loss protection, greatly improving system safety.

4.The MC20's fast motor speed tracking function can more effectively handle various situations.
