Core function
Excitation control core
As a key component of the motor excitation system,the module accurately adjusts the excitation current and dynamically adjusts the motor magnetic field strength to ensure that the generator maintains a stable output voltage when the load fluctuates,meeting the strict requirements of the power system for voltage stability.
It is suitable for scenarios such as synchronous generators and motor speed regulation,and improves power generation efficiency and power quality by optimizing the excitation control strategy.
Precise control and regulation
Supports mA-level excitation current adjustment accuracy,which can adapt to the differentiated requirements of different motor models for excitation characteristics.
Built-in wide-range adjustment algorithm,covering the full power segment application scenarios from micro generators to large industrial motors.
Multi-dimensional protection mechanism
Integrated overcurrent,overvoltage,and overheating triple protection functions.When the excitation current is detected to exceed 120%of the rated value,the module automatically triggers the protection logic,cuts off the output and generates a fault code.
Redundant sensor design is adopted,and key parameters(such as temperature)are cross-validated through dual-channel sampling to avoid false protection caused by single-point failure.
