BRX Tamagawa FA-SOLVER Type 800123-T Resolver 26V with 16mm Shaft

Buy online your BRX Tamagawa FA-SOLVER Type 800123-T Resolver from our e-store Cnc-shopping, specialist in CNC machine-tools spare parts.

The TAMAGAWA FA-SOLVER is a rotary resolver used for precise position feedback in resolver based servo axes and spindle orientation circuits. It converts mechanical rotation into two analog sine and cosine signals energized by a 26 V AC reference, delivering stable feedback to CNC drives and motion controllers even in tough shop floor conditions. The 16 mm shaft makes it suitable for direct coupling to motor shafts, rotary tables and geared actuators used across machine tools and industrial automation.

This resolver operates as a brushless rotary transformer, so there are no fragile optics. The magnetic sensing principle tolerates oil mist, dust and vibration commonly found in lathes, machining centers and heavy equipment. When installed with the proper coupling and alignment, the resolver provides smooth, low noise position feedback that helps the drive close the loop with consistent accuracy.

In service, it pairs with resolver interface electronics on servo drives or control boards that accept SIN and COS signals with a 26 V excitation. Typical use cases include axis feedback on feed motors, spindle orientation, rotary indexers and positioning actuators that were originally designed for the Tamagawa FA-SOLVER family. For replacements or retrofits, match the electrical excitation, transformation characteristics and the 16 mm mechanical interface with the existing assembly and connector style.

The reference 800123-T helps maintenance teams cross reference the exact mechanical form and electrical rating. When replacing a worn or faulty resolver, verify coupling length, mounting face, and cable termination to ensure proper drop in installation without modifying the host motor or bracket.

On the production floor this model is commonly selected to restore axis following stability and reliable homing after encoder or resolver related alarms, oscillation or loss of position feedback. It is a practical CNC replacement component when bearings in the original resolver have worn, when cables are damaged, or when optical encoders cannot survive coolant and shock.

Many maintenance teams keep at least one stocked spare per critical axis to minimize machine downtime. The 16 mm shaft format simplifies field replacement on motors and rotary units that already use this size, which shortens troubleshooting time and helps bring equipment back online faster.

Frequently asked questions about 800123-T:

How can I confirm compatibility with my drive or controller
Match the 26 V AC excitation with your drive manual, then check the electrical transformation characteristics required by the interface board. Verify the 16 mm shaft, mounting face dimensions and connector or lead configuration against the original resolver.

Is this resolver absolute at power up
Resolvers provide analog absolute position within a single mechanical turn through SIN and COS signals. Multi turn position retention depends on the drive or CNC control, so homing behavior follows the system configuration.

Can it replace a different FA-SOLVER code
Only if the electrical specification and mechanical form match. Use the 800123-T code and your existing part markings to cross check excitation rating, shaft diameter, flange details and connector pinout before ordering.

What are common signs that the original resolver needs replacement
Frequent axis following errors, unstable homing, spindle orient faults or signal imbalance readings during diagnostics often indicate bearing wear or internal degradation. A verified tested unit as a direct replacement helps restore stable feedback quickly.
