A 750 W servo replacement needs the revision suffix—not just the frame size

The July 2026 R-series manual lists two 80CB075C motors with the same 750 W power, 3000 r/min speed and 2.39 N·m rated torque, yet different current, peak torque and rotor inertia. These are a useful example of why a 220 V servo order should preserve the full motor code and approved drive configuration. The comparisons here apply to the identified R-series entries, not every historical 220 V SYNTRON motor.

80CB075C-R58A14 versus 80CB075C-R58A12

Both entries are rated 220 V, 750 W and 3000 r/min. The last two digits are the catalogue’s version field. The values below are transcribed from their individual columns, without treating the versions as interchangeable.

The same electrical reference can still need a different installation envelope

The size-80 drawings and length table distinguish integrated versus separate encoder construction and the addition of a brake. They should accompany the quotation, particularly when replacing a motor inside an existing machine.

Allow space for the selected encoder and brake package

For both 750 W entries, dimension L is 120 mm without a brake or 154 mm with a brake in the thicker configuration. The thin configuration is 101 mm without a brake or 135 mm with a brake. The manual identifies integrated encoders as the thicker construction and separate encoders as the thinner construction. These are alternatives to specify, not one universal motor length; shaft projection, connectors and cable bending space also need allowance.

Confirm the shaft, register and hole circle

The size-80 outline shows an 80 mm face, 19 mm keyed shaft, 70 mm register and four 6 mm through holes on a 90 mm pitch circle. Ask for the toleranced drawing of the delivered variant and compare the coupling and machine mount. A common 750 W rating does not establish mechanical compatibility with another supplier’s motor.

Check a new drive setup instead of copying old parameters

The two 750 W versions have different listed current, rotor inertia, resistance and back EMF. Preserve the exact motor reference in the drive parameter set and obtain a confirmed motor/drive pairing. For an accelerating axis, submit load inertia and its transmission ratio as well as the torque-versus-time duty; a peak-torque figure by itself does not establish repeatable overload duration or thermal suitability.

Resolve feedback and stopping requirements before ordering cables

The model key distinguishes CB small-inertia and MB medium-inertia families, encoder type, pole-pair count, connector/brake type and version. Keep those fields on the purchase specification.

R58 is not a promise of a 17-bit absolute encoder

In the R-series key, 5 denotes five pole pairs and encoder code 8 denotes a 2500-line magnetic encoder. Code 4 is the separately listed 17-bit absolute encoder option. Specify the actual feedback type, connector pinout and drive support; do not upgrade an 8-coded example to absolute feedback in the inquiry merely because that option exists elsewhere in the family.

Brake dimensions do not provide a brake rating

The drawing table offers with-brake lengths, but the selected 750 W performance columns do not provide a holding-brake torque, release time or stopping-energy rating. If the axis must hold a load after power removal, request the exact brake specification and control sequence. Do not count the motor’s 7.2 or 8.36 N·m peak torque as a mechanical brake holding rating.

Define the operating environment with the assembly

The R-series manual states insulation class B, −20 to +50 °C ambient and IP65. Treat that as the manufacturer’s stated motor protection level, not permission for immersion or any washdown process. Confirm seals, mating connectors and the intended exposure for the completed motor-and-cable assembly. Identify the July 2026 manual and the full version code when asking for the approved drawing.

CATALOGUE OVERVIEW

About this motor series

SYNTRON lists a 220 V AC servo motor family with model-specific power, rated torque, speed and winding data. One catalogue example is the 60CB040C-R58A11: 400 W, 1.27 N·m rated torque and 3,000 rpm. These example values apply to that model only.

Select the matching servo drive and feedback interface as a system. Supply the load inertia, acceleration, continuous torque and peak operating cycle, then confirm encoder, brake option and cable connections on the quotation.
