Product Description:

21BRCX-520-A7B/10 is a resolver designed for industrial automation applications, offering precise position feedback. The resolver features a BRCX system type, which efficiently supports both single and multiple speeds to meet diverse operational demands. This model has a compact frame size of 21 contributing to its suitability for integration into machinery with limited space and a housing mount configuration of Type 520. The excitation frequency is 10 kHz ensures reliable performance in dynamic industrial environments, enhancing accuracy and responsiveness. It's engineered to fit a minimum outer diameter of 2.06 inches (52.4 mm), with a maximum inner diameter of 0.8007 inches (20.34 mm).

The resolver is configured to operate with an input voltage of 7 VRMS which is designated as Code A. The system consumes a typical input current of 50 mA during operation, making it energy efficient for continuous use. This model also has a good Tr value of 0.5, making it more reliable with use. The design includes considerations towards electrical characteristics, showing a phase shift of -5°, which ensures minimal signal distortion during operation. The typical mechanical thickness of 1.25 inches (31.8 mm) aids in streamlined integration across various setups; also it has a basic outer diameter of 2.1 inches.

Concerning impedance specifications, the rotor impedance measures 184 Ω, while the stator impedance is 493 Ω, optimizing signal transmission quality for precise control operations. The resolver has also been designed to minimize unwanted signals; consequently, the null voltage is 20 mV, aligning the device with rigorous industry requirements where cleaner signals result in more precise and more controlled automation processes. The resolver's specifications focus on system efficiency by confirming its compatibility and precision through a variety of industrial tasks, delivering reliable function through varied operational frameworks.
