Buy online your RADIO ENERGIE RE.0444 R1CB 0.06 CA Tachymetric Dynamo from our UK e-store Cnc-shopping UK, specialist in CNC machine-tools spare parts.

The RADIO-ENERGIE RE.0444-R1CB-0.06-CA is a French-built tachometric dynamo designed to provide analog speed feedback for CNC machines and industrial equipment. It converts rotational speed into a proportional voltage signal, allowing servo drives and spindle controllers to maintain accurate and stable velocity regulation.

With a voltage constant of 0.06 V/rpm, a maximum speed of 5000 rpm, and a maximum current rating of 0.18 A, this unit is suitable for CNC lathes, machining centers, grinding machines, retrofit projects, and other applications using analog drive systems. Mounted on a motor or gearbox shaft through a coupling, it delivers reliable speed feedback for smooth operation and consistent machine performance.

The RE.0444-R1CB-0.06-CA is commonly used as a replacement part during maintenance, motor rebuilds, and troubleshooting of legacy CNC systems. Its robust construction, reliable signal output, and compatibility with older analog control architectures make it an effective solution for extending machine life and minimizing production downtime.

Frequently asked questions about RE.0444-R1CB-0.06-CA:

How do I confirm compatibility with my drive and motor setup
Check the voltage constant coding, mechanical mounting, shaft size and coupling, rotation direction and output polarity against your drive manual. Matching these points ensures correct scaling of the velocity loop and stable tuning.

What does the 0.06 CA suffix indicate on this RADIO-ENERGIE model
It refers to the manufacturer’s variant coding, which typically relates to the electrical constant and configuration. Always verify the exact constant and wiring specification in your equipment documentation before ordering a replacement unit.

Can this unit replace an encoder or resolver
No. A tachymetric dynamo provides analog speed feedback for the velocity loop, while encoders and resolvers supply position or incremental feedback to the control. Many legacy systems use both, with the tacho handling speed regulation and the encoder providing position data.

What should be checked after installation
Verify shaft alignment and coupling fit, confirm output polarity with the drive, and validate voltage scaling across the typical speed range. Monitoring ripple and linearity under load helps confirm correct operation before returning the machine to production.
