21BRCX-500-JC7A by Danaher

The 21BRCX-500-JC7A resolver, manufactured by Danaher and belonging to the Dynapar Resolvers series, is engineered for high-precision industrial feedback applications. This brushless resolver features a System Type: BRCX series brushless resolver with a Configuration: rotor primary configuration and a compact Frame Size: 21 series housing with a Diameter: 2.1 in OD. It operates with an Excitation Voltage: 20 V input to generate strong, consistent signal outputs under demanding conditions. The unit’s Phasing Direction: CCW orientation supports counter-clockwise phasing, making it compatible with systems that require reversed signal sequencing. Weighing just Weight: 11 oz, the 21BRCX-500-JC7A offers a favorable power-to-mass ratio for space-restricted assemblies. Index and secondary windings are marked as Index Signal: N/A and Secondary Signal: N/A, simplifying wiring harnesses and reducing potential failure points.

Performance is characterized by stable resolver feedback across continuous rotations, ensuring linear output even under high-speed or variable-load conditions. The resolver’s absence of index and secondary signals eliminates complex signal conditioning while maintaining precise angle detection. Parameterized values such as Parameter A: 26 and Parameter B: 12 are derived from Danaher datasheets to ensure consistent alignment and control quality. Its brushless design mitigates wear and extends operational life by removing commutator and brush assemblies. Rugged construction withstands vibration and mechanical shock, delivering uninterrupted electrical performance in incessant motion. Moreover, the resolver’s counter-clockwise phasing contributes to predictable signal phase relationships, facilitating straightforward tuning during system commissioning.

Built for industrial automation, the 21BRCX-500-JC7A resolver provides exceptional reliability in servo-driven machines and rotary positioning solutions. Its robust enclosure and precision windings guarantee long-term stability under constant operating loads and harsh environmental stresses. Easy phasing and clear electrical output simplify integration with controllers, reducing commissioning time and engineering overhead. The compact frame and lightweight design enable installation in confined spaces without compromising performance. Ideal for applications in robotics, CNC machinery, and motion control systems, this Danaher resolver excels where accurate, continuous feedback is essential.
