Product Description:
The 15BRCX-500-J12 is a compact and rugged rotary feedback resolver specifically designed for high-precision motion control systems. This resolver is used in analog systems that require reliable, real-time angular feedback without any reliance on digital encoders. Manufactured by Danaher this resolver comes with a nominal outer diameter of 1.5 inches to permit a seamless integration within servo systems where space is a concern.
This resolver incorporates a steel housing to provide structural integrity in tough industrial conditions. A single servo groove mounting configuration provides this resolver a safe and vibration-resistant mounting in high-performance mechanical assemblies. The housing is 1.625 inches long and includes a 1.440-inch pilot, which makes this resolver ideal for closely packed setups. This resolver works on a BRCX system type with various speed options, and it utilizes a stator as the primary element to provide improved signal stability and system compatibility. The rotor bore is accurately machined to 1/4 inch, which ensures precise shaft coupling and limits the axial runout. The internal electrical parameters of this resolver are optimized with an input excitation current of 55 mA and an input excitation frequency of 7 kHz to provide high signal resolution and clarity in feedback applications.
The input excitation voltage of 4.25 Vrms helps the 15BRCX-500-J12 resolver in precise signal transmission over various load conditions. The electrical resistance ratings of this resolver are calibrated precisely with the rotor resistance at 14 ohms and the stator resistance at 30 ohms. This calibration ensures high electrical efficiency and phase synchronization of the rotor and stator signals. This resolver is calibrated at +4 degrees of phase shift for enhanced signal processing within analog feedback loops. The rotor length of 1 inch makes this resolver a compact profile while maintaining mechanical rigidity and accurate rotation tracking.
