Product Description:
The 21BRCX-320-H is resolver for heavy-duty jobs. It is part of Resolvers series having sturdy construction. The resolver is brushless and has features for reliable tracking of position. It has an outer diameter of 2.1 inches and is referred to as size 21. The size accommodates industrial systems that have a tight space.
BRCX series provides rotor-primary operation with free speed handling. It has a single or multiple speed capability per application requirements. The input voltage is approximately 7 V rms, ±5% typical value. The level provides clean operation in most types of control systems. Excitation frequency is approximately 10 kHz ±1%, typical for this series. The excitation is stable to allow consistent resolver signal generation. Input current is roughly 50 mA rms for normal use. This value corresponds to current draw for comparable BRCX models. The ratio of transformation is 320:1, as indicated by the name. This ratio enables clean signal separation for position sensing. Rotor DC resistance is around 34 ohms for consistent readings. Stator DC resistance is around 74 ohms, which is normal. These resistances enable consistent system performance in environments. Impedance (Zro) is around 184 ohms in typical BRCX units. This enables proper signal strength and lower electrical noise output. The working temperature range is up to 200C maximum. This enables application in hot, high-load conditions without failing.
The 21BRCX-320-H is capable of continuous operation at 1,000 RPM speed. It is stable even under long duty cycles and heat. Weight is approximately 200 grams, which enables support in compact mechanical systems. This resolver is designed for reliable feedback under harsh conditions. The 21BRCX-320-H combines strength, accuracy, and consistent signal performance. A robust option for equipment that requires long-term accuracy.
