Product Description:
The latest Dynapar 11BRW series, which the Danaher made 11BRW-300-C-10/5 pertains to, forms part of a gearing based resolver for precision and demanding systems. With a phase shift of 4°, such a resolver can somewhat eliminate position error at the time of processed feedback. A total of 15 mV, or a null voltage, is a minimum differential voltage of the differential voltage at zero position, resulting in higher fidelity of signal and more accurate angular feedback. Using pulse count and termination setup as the 10/5 ordering designation allows us to provide users with a precise configuration.
This resolver variant can be used in a wide temperature range of -40°C to +120°C with a guaranteed reliability. Rated to 50 G’s for 11 milliseconds, the drive offers shock resistance for maintaining signal integrity. It is a part of the brush less, heavy duty, 11BRW series providing a longer life cycle. By mounting the rotor on a field replaceable redhead, on site servicing is easier resulting in less equipment downtime. The module improves to a speed rating of 7 (similar to other 11BRCX-300C models) for high efficiency rotation in mid speed electronic feedback systems. It achieves primary accuracy 6.0 arc-min, providing tighter positional data control. At high response speed, the cleaner signals are obtained at the excitation frequency of 1,000 Hz.
The part number 11BRW-300-C-10/5 supports long-term reliability even in an active automation assembly. The resolver uses an input current of 15 mA, minimizing power consumption in closed-loop setups. A voltage transformation ratio of 0.45 (Vout/Vin) means it effectively scales input voltages to manageable levels for signal interpretation. Based on recent data, it has a rotor inertia of 0.00056 oz-in-sec² and provides smoother transitions in motion-sensitive systems. The insulation resistance exceeds 100 MΩ at 500 VDC, helping prevent leakage currents and maintaining isolation.
