Product Description:
Danaher is the manufacturer of 11BRW-300-F1/10 which is a Resolver. This module belongs to the Dynapar Resolvers series. It offers stable operation under continuous load conditions in the industrial automation applications.
The 11BRW-300-F1/10 resolver stator winding is applied with 2,500 Hz frequency of the AC signal which allows for faster and more accurate position sensing, especially in high-speed applications. It is designed with minimal physical length, which makes it easier to fit into tight spaces and makes it ideal for applications where space is limited, such as in servo motors or robotics. The standard operating voltage to be applied to the resolver's stator winding is 12.0 Vrms which reflects the AC voltage level needed for proper functioning. The expected signal output from the rotor is 6 volts and it reflects the induced voltage based on the position of the rotor and suggests a strong and clear signal for the downstream electronics to interpret. It is built to withstand high-radiation environments which makes it suitable for critical and harsh missions. There is a phase difference of -2° between the excitation input and the signal output which indicates high accuracy in angle tracking and minimal signal distortion.
The 11BRW-300-F1/10 resolver draws 3.1 mA RMS AC current during normal operation which implies high efficiency and low power consumption. Its stator receives a two-phase 12V signal to generate the rotating magnetic field necessary for position sensing. It comes with a mass of 0.45 kg which shows it is relatively lightweight and contributes to less mechanical load, which is beneficial in dynamic or moving assemblies. It can function reliably at high ambient temperatures up to 125°C.
Frequently Asked Questions about 11BRW-300-F1/10:
Q: Why does the resolver use a 2,500 Hz excitation frequency instead of a lower one?
A: Higher frequency improves position resolution and dynamic response. It helps the 11BRW-300-F1/10 resolver perform better in high-speed applications.
Q: How does the compact size of the resolver benefit system integration?
A: Its minimal length simplifies mounting in tight mechanical assemblies. This makes it ideal for space-constrained industrial automation systems.
Q: What is the importance of the -2° phase shift in 11BRW-300-F1/10?
A: A minimal phase shift ensures signal fidelity and accurate angle tracking. This results in better synchronization with control systems.
Q: How does radiation hardening enhance the 11BRW-300-F1/10 resolver’s reliability?
A: It protects internal components from ionizing radiation damage. This makes the resolver suitable for aerospace and defense applications.
Q: Why is a two-phase stator input used in 11BRW-300-F1/10 instead of single-phase?
A: Two-phase excitation provides sinusoidal reference signals, improving angular accuracy. This supports more precise position feedback for servo control.
