Excitation system measurement board plays an important role in the operation of the motor, the following is a detailed introduction to it:

Definition and function

UNS0887A-P 3BHE008128R0001 Excitation system measurement board is a key component in the excitation system, its main function is to provide excitation current to the coil of the motor, thereby generating a magnetic field to drive the motor operation. In addition, the exciter board also protects the motor from overvoltage and overcurrent damage, and automatically adjusts when the motor is subjected to these abnormal conditions to ensure the normal operation of the motor.

2. Technical requirements

The driving circuit of the excitation system measurement board (such as the UNS0887A-P 3BHE008128R0001) must meet the following five requirements:

When the switch tube is turned on, the charging current provided by the drive circuit should make the MOSFET gate source voltage rise rapidly to the required value, ensuring that the switch tube can be turned on quickly and there is no high frequency oscillation of the rising edge.

During switching, the driver circuit should be able to maintain the stability of the MOSFET gate source voltage to ensure that the on-state continues.

At the moment of switching off, the drive circuit should be able to provide a path with as low impedance as possible for the rapid discharge of the capacitor voltage between the MOSFET gate source electrode to ensure that the switching tube can be quickly turned off.

The structure of the drive circuit should be as simple as possible and the loss should be small to improve the overall efficiency.

Depending on the actual situation, the drive circuit may need to apply isolation measures to ensure the safe and stable operation of the system.

3. Application and scope

The UNS0887A-P 3BHE008128R0001 excitation system measuring board has a wide range of applications in various types of motors, the most common of which are AC motors and DC motors. In the AC motor, the excitation board is usually composed of capacitors, transformers, etc., and generates the required DC current by rectifying and filtering the AC current. In the DC motor, the excitation board is composed of DC power supply, current limiting inductance, etc., through the DC current limiting, voltage stabilizing treatment, to ensure the stability of the excitation current.

In addition, with the continuous development of science and technology, the application range of excitation boards is also expanding. Nowadays, it has been widely used in power systems, industrial production and new energy fields, and has become an indispensable part of motor operation.
