Product Description:

Danaher produces the Brushless Resolver designated as 11BRW-300-B95-01. The resolver has a compact size 11 design. This resolver operates as a control transformer type. It operates at a single speed and delivers high measurement precision in industrial automation. Its excitation frequency is fixed at 2500 Hz.

The accuracy of 11BRW-300-B95-01 resolver is ±3 arcmin (0.05°). This resolver simultaneously sustains 1 lb of axial load force. The starting torque is minimal at 0.08 oz-in. The resolver provides a 6.0 V output voltage under normal operating conditions. The required operating voltage of the resolver is 12.0 V while the frequency of the input signal is set at 2500 Hz. The design supports 10 mA as its maximum current intake. The maximum value of power input does not reach 21 mW. The output signal applies a +5° phase rotation. The maximum value of null voltage permissible through the 11BRW-300-B95-01 resolver reaches 15 mV. The DC rotor resistance of this resolver is measured at 40 Ω. The total DC stator resistance of this unit reaches 132 Ω. The transformation ratio operates at 0.5 along with a tolerance level of ±5%. It allows up to 2 lbs of radial force through its shaft. Mechanical pressure resistance becomes possible due to the way the resolver has been built. The brushless construction makes it possible for the device to require less maintenance.

The 11BRW-300-B95-01 resolver uses its design to transmit signals with high reliability. This resolver provides constant functionality in challenging situations. Relevant data shows that the magnetic system has 0.51 × 10-⁴ oz-in-sec² as its moment of inertia. The device operates with enhanced operational efficiency because of its low power usage. It works effectively in temperature ranges between -40°C and +125°C.
