Product Description:

The 15BRX700-D10AA is a pancake-style resolver manufactured by Danaher within the Dynapar Resolvers series. The device serves as a position transducer that converts mechanical shaft angle into a pair of analog reference signals for servo amplifiers, PLCs, or numerical controls. With a basic outside diameter of 1.5 inches and an aluminum housing, it fits into tight motor endbells while withstanding vibration and elevated temperatures often found in automated assembly, packaging, and material-handling equipment.

Electrical excitation for the resolver is specified at an operating frequency of 8 kHz, driven by a supply of 8 Vrms. At this level, the primary winding draws only 50 mA, minimizing heat generation in densely packed motor compartments. The rotor winding presents a reference-to-output impedance of 182 ohms, which balances drive loading and signal strength for most standard resolver interfaces. Once energized, the secondary winding delivers output voltages that track shaft angle at a transformation ratio of 0.50, meaning each secondary amplitude is one-half of the applied excitation. A null output of 30 mV indicates the residual error when the shaft is aligned with the electrical zero, supporting precise homing routines.

The secondarily coupled circuit exhibits an impedance of 627 ohms, permitting long cable runs without excessive current loss, while the stator windings measure 116 ohms and the rotor windings measure 55 ohms. These resistance values influence thermal rise and determine compatible drive excitation profiles that keep coil temperatures within limits. Mechanical alignment accuracy is characterized by a peak-to-peak error of 16 arc-min, allowing reliable interpolation by modern digital drives. A 1.449-inch pilot diameter centers the resolver on mating hardware, and the 3/8-inch rotor bore coupled with a 0.635-inch rotor length supports direct mounting to precision shafts without additional adapters.
