Product Description:
Danaher produces the Resolver with the product code of 11BRCX-300-E-74. The Resolver serves systems that need precise rotational position information in industrial automation. Operation of the resolver takes place at a continuous speed of 1 while running a 2500 Hz signal that has a tolerance range of ±5%. The resolver accepts a 12.0 V input voltage at 2500 Hz. This does not exceed 10 mA of input current.
The 11BRCX-300-E-74 resolver uses 21 mW as its highest power consumption. The resolver generates a 6.0 V output voltage with a transformation ratio between 0.5 and +5% of this value. It achieves stable power performance through precisely designed electrical specifications. The resolver contains rotor resistance at 40 ohms while the stator resistance reaches 132 ohms. The total null voltage remains limited to 15 mV while assisting error reduction in signals. The phase shift control operates at +5°, which leads to guaranteeing secure signal timing. This 11BRCX-300-E-74 resolver provides precision control through its accuracy error limit of ±3 arcminutes at a temperature of 25°C. This resolver has a moment of inertia measuring 0.51 × 10-⁴ oz-in-sec². It also has a static torque strength of 0.08 oz-in. The resolver can handle shaft loading up to 2 lbs. radial and 1 lb axial. The set specifications guarantee stable mechanical and electrical operability.
The 11BRCX-300-E-74 resolver operates successfully between -40°C and +125°C. Such broad operating temperatures work well for challenging industrial tasks. The resolver maintains stable signal transmission while reducing electrical noise effects. The technical characteristics of reduced input power alongside precise accuracy tolerance make this device appropriate for automated motion systems. Position feedback accuracy is vital for systems that this component enables to function effectively.
