Product Description:

The 11BRW-300-M10B brushless resolver designed by Danaher is a housed resolver. This product houses a rotary transformer and a precision bearing system. The device supports a coupling mounting action. This unit has no life-limiting components like a brush and a slip ring sliding contact. It does not need any regular maintenance. This resolver is best noted for repeatability as well as angular accuracy.

The product has support for single-speed operation. This device’s operation can be done between -55 °C and 125 °C. The unit’s mass is very less and it has a compact size. It has an excitation frequency of 5 kHz with a tolerance of +/-5%. This resolver is marketed using the Harowe brand. The product comprises continuous electrical inputs for one full revolution performed mechanically. This device helps in shaft angle encoding. The unit delivers exceptional performance in high-temperature environments. Its rotor has a 3.6 g-cm² moment of inertia.

This resolver has very good ruggedness and robustness. The product features an 11 size code. This device offers accurate motion control feedback by measuring angular position. The unit uses wire leads with 28 AWG and a length of 12 inches for termination. It has a robust design and portrays high durability. This brushless resolver can be used only for industrial applications and not for residential needs. The product design shows a very small diameter of 0.12 inches for the bore or shaft. This device has high-quality instrument-grade or motor-grade ball bearings. It meets all desired accuracy level requirements. The unit includes no separate tachometer in its construction. It delivers a velocity signal with high precision and infinite resolution.
