11BRW-300-F-95A-01 by Danaher

The 11BRW-300-F-95A-01 resolver from Danaher encapsulates robust feedback performance within the Dynapar Resolvers series. Engineered as a heavy-duty brushless device, this SERIES 11/R11 Heavy Duty Brushless Resolver - Harowe brand unit delivers a Transformation Ratio of 0.50 Vout/Vin and operates on a nominal Input Voltage of 12.0 Vrms. With a Frequency Response rated at 2,500 Hz, it maintains signal integrity across demanding speed profiles. The resolver’s Total Null Error is specified at 30 arc-minutes, ensuring precise angular alignment under dynamic load conditions. Early integration into servo and industrial automation environments is streamlined by its compact form and standardized mounting patterns.

Performance characteristics are tailored for heavy-duty industrial applications, beginning with an Input Current consumption of 3.1 mA, which minimizes power draw while preserving signal accuracy. The device sustains reliable operation over an Operating Temperature Range up to 125°C, making it suitable for high-temperature and high-vibration environments. A Phase Shift of –2 degrees contributes to system stability by offsetting timing discrepancies between excitation and response signals. The resolver features a Rated Speed Parameter of 7, calibrated to match common motor velocity profiles in precision motion control. The turn ratio’s direct control over output-to-input voltage gain allows seamless compatibility with downstream electronics and feedback loops.

Reliability is ensured through Danaher’s rigorous manufacturing and quality assurance processes, delivering consistent performance across extended duty cycles. Integration with industrial drives and PLCs leverages the standardized resolver output signal for closed-loop position feedback. Typical applications include servo motors, robotics, CNC machinery, and power generation equipment where angular resolution and phase fidelity are critical. The unit’s heavy-duty brushless architecture reduces wear and eliminates the need for maintenance-prone brushes, extending service intervals and system uptime. With its combination of precision specifications and industrial-grade construction, the 11BRW-300-F-95A-01 resolver is an ideal solution for demanding automation tasks.
