Product Description:
The 15BRCX-600-J17 is an electromechanical resolver supplied by Danaher within the Dynapar Resolvers series. In motion-control assemblies, this part attaches directly to a motor shaft and outputs complementary sine and cosine voltages that represent the rotor angle, allowing a controller to calculate absolute position and speed without digital encoding. The resolver tolerates high temperatures, electrical noise, and vibration, making it suitable for precision feedback in packaging machines, robotics, and automated tooling.
The stator is energized with an excitation carrier of 7 kHz, delivered at an input of 4.25 Vrms while drawing 55 mA. These values provide the reference amplitude and adequate magnetic coupling without overheating the 1.0-inch frame. Under these conditions, the resolver produces secondary voltages scaled by a transform ratio of 0.47, meaning the sine and cosine outputs reach approximately half the applied reference voltage. Electrical loading on those outputs is characterized by a Zro impedance of 42 + j72 Ω. The quadrature error between the channels remains within ±4 degrees of the ideal relationship, providing predictable phase information for angle calculations.
During operation, the resolver can track shafts at speeds up to 1,000 rpm without signal roll-off, and its null, or residual, output remains below 20 mV, simplifying drive-side zeroing routines. The secondary circuit presents an impedance of 70 + j107 Ω, while the rotor winding has a resistance of 14 Ω and the stator winding has a resistance of 30 Ω. These electrical values support proper impedance matching with the connected control electronics. The unit centers in a 1.449-inch pilot, accepts a 0.437-inch rotor bore, and has a rotor stack length of 1.53 inches, allowing it to fit common servo shafts directly. Its total mass is 4.5 ounces, which minimizes inertial loading on lightly coupled motors.
