Bobine de régénération ACOPOSmulti B&R 8BVR0440H000.100-2

Product Overview

The 8BVR0440H000.100-2 (8BVR0440H0001002) is a high-capacity industrial regeneration choke specifically engineered for the B&R ACOPOSmulti drive system. This critical electromagnetic component is designed to work in conjunction with active power supply modules to facilitate the return of regenerative braking energy back to the mains supply. By filtering and smoothing current during energy recovery, the 8BVR0440H000.100-2 minimizes harmonic distortion and enhances the overall energy efficiency of multi-axis motion control systems. It is an essential element for high-inertia applications such as heavy-duty centrifuges, elevators, and large-scale printing presses where frequent deceleration phases would otherwise result in wasted thermal energy.

Technical Configuration

This regeneration choke is optimized for high-power throughput and robust thermal management within industrial power grids.

• High Current Handling: Supports a continuous current of 45 A, making it suitable for demanding motor loads and high-torque applications.

• Wide Voltage Range: Designed for three-phase systems ranging from 220 VAC to 480 VAC (plus or minus 10 percent), providing global compatibility for various industrial power standards.

• ACOPOSmulti Integration: Specifically tuned to the switching frequencies of the ACOPOSmulti series, ensuring maximum electromagnetic compatibility (EMC) and reducing stress on the DC bus capacitors.

• Integrated Terminal Blocks: Features heavy-duty terminal blocks for secure, vibration-resistant electrical connections capable of handling the 17 kg mass of the inductive core.

Technical Specifications

FAQs

What is the primary function of the 8BVR0440H000.100-2?

This choke is used during regenerative braking. When a motor decelerates, it acts as a generator. The choke filters this generated energy so it can be safely and efficiently fed back into the power grid instead of being dissipated as heat through a braking resistor.

Can this choke be mounted in any orientation?

Due to its significant weight (17 kg) and the need for convective cooling, the choke should be mounted according to the manufacturer's specified orientation (typically vertical) to ensure heat is effectively dissipated from the windings.

Is this component compatible with third-party drives?

No, the electrical characteristics (inductance and saturation levels) of the 8BVR0440H000.100-2 are specifically matched to the B&R ACOPOSmulti active power supply modules. Use with non-B&R hardware may lead to inefficient energy recovery or damage to the power electronics.

Engineering Installation and Thermal Management

• Mechanical Security: The 17 kg weight of the unit requires a reinforced mounting plate within the control cabinet. Use all provided mounting holes and ensure the cabinet structure can support the static load and any dynamic forces caused by industrial vibration.

• Heat Dissipation: Regeneration chokes generate significant heat during heavy braking cycles. Maintain the minimum specified clearance distances (top and bottom) to ensure unobstructed airflow. If the ambient temperature exceeds 40 deg C, forced ventilation or a reduction in duty cycle may be required to prevent thermal cutout.

• Wiring Standards: Use high-temperature rated industrial cabling for the connections to the 45 A terminal blocks. Ensure all connections are torqued to the official B&R specifications to prevent contact resistance, which can lead to localized overheating and fire hazards.

• EMC Considerations: To minimize interference with sensitive control signals, keep the power leads between the regeneration choke and the power supply module as short as possible. Use shielded cables where necessary and ensure a low-impedance ground connection to the mounting plate.
