Product Description:
The 11BRCT-300-P95D-01 Resolver designed and developed by Danaher is a perfect solution for industrial automation applications. This resolver relates to the Dynapar Resolvers Series. This module is engineered for durability and system compatibility.
The 11BRCT-300-P95D-01 resolver has a physical length of 1.590 inches which indicates how much space it takes up along its axis and is important for determining how it fits into a mechanical assembly or enclosure. It is designed to operate continuously without needing routine maintenance—ideal for industrial or aerospace applications where reliability and low downtime are critical. It comes with a stator winding, which means the windings that generate and receive signals are on the stationary part of the resolver and it is typical for brushless resolvers. The excitation voltage applied to the resolver’s reference winding is 12 v rms which is used to generate a magnetic field for position sensing. The electrical phase difference between the output signal and the excitation signal is -7°which means the output lags the input slightly important for interpreting position data accurately. It is built for demanding environments, and “brushless” design implies a longer life with no wear on contacts.
The 11BRCT-300-P95D-01 resolver is able to produce 0.39 output voltage for a given input voltage which helps in designing the signal conditioning electronics. It has the residual signal of 15 mV when it is in its null position which indicates good but not perfect alignment or balance in the resolver windings. It can function in high heat environments up to 155°C. It is designed to work with 2,500 Hz frequency. The current drawn by the excitation winding is 1.4 mA. It not only reads angles accurately but repeats those readings consistently over time and cycles.
Frequently Asked Questions about 11BRCT-300-P95D-01:
Q: Why is a brushless design important in the 11BRCT-300-P95D-01 resolver?
A: Brushless design eliminates friction and wear, improving long-term reliability. It ensures consistent performance in continuous-duty industrial operations.
Q: How does the -7° phase shift affect signal interpretation in this resolver?
A: The phase shift compensates for signal timing discrepancies. This ensures more accurate decoding of position feedback by control systems.
Q: Why is the 0.39 Vout/Vin transformation ratio used in the 11BRCT-300-P95D-01 resolver?
A: This ratio balances output voltage for better compatibility with signal conditioning electronics. It helps reduce noise interference and enhances resolution.
Q: What advantage does the 1.4 mA input current provide in the 11BRCT-300-P95D-01?
A: Lower input current minimizes heat generation and power consumption. It also contributes to longer operational life in confined assemblies.
Q: How does a 2,500 Hz excitation frequency benefit resolver performance?
A: Higher frequency improves signal responsiveness and resolution. It allows for better real-time tracking in dynamic motion applications.
