Product Description:
The 11BRCT-300-M-10A Resolver is the creation of Danaher and it comes under the series of Dynapar Resolvers. This resolver can be easily integrated into existing automation networks and it provides precise operations.
The 11BRCT-300-M-10A resolver operates at a high-frequency range of 2,500 Hz which is common for high precision and high speed applications and allows better resolution and faster response times. The module standard voltage level is 11.8 volts rms which is used to excite the resolver's reference winding that tells how much AC voltage should be supplied for normal operation. Its stator is fixed during installation while the rotor spins relative to the stator. It has 30 mV of null voltage which is the signal present at the output when the resolver is at its electrical zero which indicates good internal alignment and minimal error near the reference point. There is a slight lag of -1° in the signal phase between input and output which is minimal and means the signal response is nearly in sync with the input. It can be designed for different speeds and its 2-speed configuration gives two cycles of output signal per mechanical revolution.
When the 11BRCT-300-M-10A resolver is operating at its rated voltage and frequency it draws 70 m ampere current which is moderate and gives an idea of the power consumption and compatibility with the driving electronics. It comes with a 1.02 V_out/V_in of transformation ratio which indicates the output signal strength relative to the input excitation voltage and also helps deliver a strong, clean signal with minimal loss or amplification required. It has the accuracy class of 10 which indicates its higher precision.
Frequently Asked Questions about 11BRCT-300-M-10A:
Q: How does the 2-speed configuration enhance the resolver's signal resolution?
A: The 2-speed design provides two electrical cycles per mechanical revolution, doubling angular resolution. This allows for more accurate position feedback in motion control systems.
Q: Why is a brushless design important in the 11BRCT-300-M-10A resolver?
A: Brushless construction ensures longer operational life and reduces maintenance requirements. It enhances durability, especially in harsh or continuous-duty industrial environments.
Q: How does the fixed stator improve system alignment and stability?
A: A fixed stator ensures consistent reference positioning and easy mechanical alignment. It also reduces vibration-induced errors in rotating systems.
Q: Why does the 11BRCT-300-M-10A use a transformation ratio of 1.02?
A: A 1.02 transformation ratio ensures strong signal output with minimal distortion. It maintains signal integrity over long cable runs or noisy environments.
Q: How does the -1° phase shift affect system synchronization?
A: This minimal lag keeps the output nearly synchronized with the input signal. It supports precise timing, critical in real-time motion control loops.
