Product Description:

The 11BRW-300-F-95A-01 is a premium heavy-duty brushless resolver from the Harowe brand series offered by Danaher Company. This resolver is ideal for heavy-duty servo systems. It has an input voltage of 12.0 Vrms, and the signal frequency is below 2,500 Hz. The input current of the resolver is 3.1 mA which makes it energy efficient to ensure that it provides accurate feedback signals for motion control applications. This resolver can operate at temperatures of up to 125 degrees Celsius, making it suitable for high-temperature environments.

An important characteristic of the 11BRW-300-F-95A-01 resolver is its output-to-input voltage gain, which is about 0.50 Vout/Vin. The turn ratio directly controls how much the input voltage is transformed into the output voltage. The coefficient 0.50 indicates that the output voltage will be half of the input voltage for a one kVA to kVAr relationship. It is very useful in most applications where a high level of voltage conversion rate is required to provide accurate position feedback. It is also used to regulate the system signal power as well as provide the resolver with continuous data to transfer accurately.

Another important characteristic of this resolver is its phase shift of -2 degrees. Phase shift is defined as the relative time difference between the input and the output signals. The 2 phase shift implies that the output is shifted at a lower rate than the input signal by a phase angle of 2. This phase shift is useful for increasing the stability and efficiency of servo systems. A small controlled phase shift is beneficial and ensures proper synchronization and minimizes errors that cause disruption in the motion control systems, and improves positioning accuracy.
