ANIKRON BM-08

The ANIKRON BM-08 digital excitation regulator is designed to supply the field winding and automatically control the excitation current of industrial synchronous motors (up to 32 MW) equipped with brushless excitation systems during startup, synchronous operation, and emergency conditions.

Key advantages:

• Energy efficiency
• Reliability
• Ease of setup
• Maintainability

Technical features:

• Power amplifier as excitation source, designed using a controlled current generator circuit;
• Extended excitation control range (up to 100 V and 10 A);
• Resynchronization mode activated during prolonged asynchronous operation;
• Advanced comprehensive control algorithms;
• Fully identical, independent, and interchangeable main and backup excitation control units;
• Integrated communication interfaces: RS-485 with Modbus protocol and three 4-20 mA current loops;
• External excitation current control via 4-20 mA current loops, RS-485 (Modbus), and pulse-width modulation (PWM);
• Reliable operation within a supply voltage range of 0.6 to 1.3 of the rated value;
• Reactive current management according to predefined setpoints, including control of reactive power generation or consumption;
• Pre-start motor simulation (test mode);
• Start readiness indication, preventing motor startup if the excitation system is unready or faulty;
• Compatibility with all types of industrial synchronous motors;
• Customizable climatic execution available upon request;
• Available enclosure ratings: IP20, IP31, Ip54;
• Custom manufacturing to meet specific customer requirements (dimensions, software, design, and climatic version).

Protection features:

1. Prolonged asynchronous operation protection;
2. Loss of excitation protection;
3. Prolonged startup protection;
4. Short circuit protection for the excitation circuit and power section;
5. Overtemperature protection for thyristors and the regulator cabinet interior.
