Product Description:
The 21BRCX-310-F8-02 frameless resolver supplied by Danaher incorporates a servo mounting option. This product is a heavy-duty resolver with a 21 size code. The device encompasses a machine wound stator to operate with high accuracy. This unit offers speed commutation and feedback with enhanced reliability. Its modular construction helps in meeting any preferred accuracy levels. This resolver can also deliver velocity feedback.
The product is free of internal bearings and can be directly mounted into the desired assembly. This device’s stator comprises a customizable housing. The unit operates with a rotary transformer for limited rotation applications. Its rotor comprises a sleeve that can be modified to fit the customer’s interface. This resolver supports 1X, 2X, 3X, or 4X speed options. The product is an ideal option for servomotor feedback applications. This device has two winding sets in its laminations and are positioned away from one other by 90°. The unit’s input phase gets energized by an AC voltage and an output signal is generated. Its operation is defined by several parameters such as accuracy, null voltage, input excitation frequency and voltage, phase shift, and transformation ratio.
This frameless resolver withstands extreme temperatures unlike an encoder. The product’s electrical error is reduced by 50% because of its tooth-wound design. This device isn’t affected by radiation and has great resistance to EMI noise. The unit is also unaffected by most liquids and particulate contaminants. The unit delivers absolute position details with one revolution when it portrays single-speed operation. It is also referenced as a pancake resolver because of its design.
