Product Description:
The 11BRW-300-F1/10 resolver is produced by Danaher and supplied in the Dynapar Resolvers series. As an electromechanical angle transducer, the unit couples to a motor shaft and produces two analog sine and cosine signals that indicate rotor position to motion controllers. In industrial automation, this feedback supports closed-loop commutation, speed regulation, and homing routines in servo drives where digital encoders are not required. It employs a brushless rotary design that tolerates the high temperatures and vibration commonly found in packaging, material-handling, and metal-forming machinery.
The resolver operates with an excitation carrier of 2500 Hz; this frequency serves as the reference waveform that is injected into the primary winding and later demodulated by the drive. When the resolver receives an excitation level of 12.0 Vrms, the primary circuit draws only 3.1 mA, limiting power dissipation and simplifying power-supply sizing inside the controller. The secondary windings deliver sine and cosine outputs with a transformation ratio of 0.50, meaning each secondary amplitude is half the applied carrier amplitude. Electrical alignment between the reference and output has a phase shift of -2°, which the drive can compensate for during signal processing.
Residual error around the electrical zero is limited to a total null voltage of 30 mV, helping maintain position accuracy when the carrier is suppressed during slow shaft rotation. The rotor and stator pole counts are matched for a single-speed resolver, supplying one electrical cycle per mechanical revolution for straightforward position interpolation. Signal generation occurs entirely within the stator winding set, eliminating brushes and reducing maintenance requirements. The unit belongs to the Dynapar Resolvers series and uses the mechanical interface and electrical profile associated with this product line.
