Product Description:
The 11BRW-300-F95A-01 resolver is an electromechanical position feedback device produced by Danaher and supplied under the Dynapar Resolvers series. Designed for industrial automation, this resolver converts mechanical shaft angles into analog sine-cosine signals that withstand high temperatures, vibration, and electrical noise in environments where optical encoders may fail. Its brushless design uses transformer-like coupling and contains no onboard electronics that could overheat. This design supports reliable operation during demanding industrial duty cycles.
During excitation, the primary winding accepts 12.0 Vrms at 2500 Hz. That stimulus draws only 3.1 mA, so the drive electronics can use a small carrier amplifier. The resolver’s secondary produces sine and cosine outputs at one-half of the primary amplitude, based on a transformation ratio of 0.50. This fixed ratio simplifies resolver-to-digital converter scaling and keeps the differential signals within standard ±6 V ranges. Electrical alignment between the primary and secondary axes is nearly ideal. The residual phase error is limited to -2 degrees, minimizing interpolation offsets in digital converters.
The resolver has an electrical speed rating of 1, corresponding to one electrical cycle per mechanical revolution. This relationship allows the drive to calculate absolute shaft position without gear corrections. When the rotor and stator axes coincide, the output drops to a residual level of only 30 mV, indicating tight magnetic symmetry and simplifying zero-offset calibration. The primary coil is located on the stator, so excitation does not pass through slip rings. Eliminating slip rings reduces mechanical wear and supports a longer service life in high-cycle applications. The analog output format also allows compatible control hardware to monitor shaft position continuously while maintaining resistance to the electrical interference commonly found around motors, drives, and industrial power equipment.
