The principle of the motor shaft current meter is to use the Hall effect to detect the current of the motor shaft. The Hall effect is an electrical effect based on a magnetic field. It can convert the change of the magnetic field into a voltage signal to achieve the measurement of the current. The motor shaft current meter is usually composed of components such as a Hall sensor, a circuit board, and a display screen.

During the operation of the motor, the motor shaft will rotate continuously, and a magnetic field will be generated during the rotation. The motor shaft current meter measures the current of the motor shaft by installing the Hall sensor near the motor shaft and using the change of the magnetic field. When the current passes through the motor shaft, a magnetic field is generated, and the Hall sensor detects the change of this magnetic field and converts the change into a voltage signal, which is then processed by the circuit board and finally displayed on the display screen.

2. How to use the motor shaft current meter

1. Install the motor shaft current meter

First, you need to install the motor shaft current meter near the motor shaft. The specific installation position should be determined according to the specific situation of the motor shaft. It is usually recommended to install the motor shaft current meter at the end of the motor shaft. During installation, care should be taken to avoid friction and collision with the motor shaft to avoid affecting the measurement accuracy.

2. Connect the motor shaft current meter

Next, you need to use a cable to connect the motor shaft current meter to the motor control system. Pay attention to the length and quality of the cable when connecting to avoid affecting signal transmission and measurement accuracy.

3. Calibrate the motor shaft current meter

Before using the motor shaft current meter, you need to calibrate it first. Usually, the calibration process requires the use of a standard current source for comparison. For specific calibration methods, please refer to the instruction manual of the motor shaft current meter.

4. Use the motor shaft current meter

After completing the calibration, you can start using the motor shaft current meter. Usually, the motor shaft current meter will display the measurement results on the display in real time, and you can perform real-time monitoring and data recording as needed. At the same time, the motor shaft current meter can also use the alarm function to remind you of abnormal conditions of the motor shaft, so as to deal with the problem in time.

The motor shaft current meter is a very practical instrument and equipment. It can help you monitor the current of the motor shaft in real time, and find and deal with problems in time, thereby improving production efficiency and reducing losses. When using the motor shaft current meter, you need to pay attention to issues such as installation, connection, calibration and use to ensure measurement accuracy and reliability.
