FAQs

What is an 80mm servo motor?

An 80mm servo motor is a mid-size permanent-magnet AC servo on an 80 mm flange, the NEMA 32 frame size. It sits a step above the 60 frame, with more torque for mid-size machines, and runs closed-loop on a 17-bit absolute encoder so the drive always knows rotor position and holds it under load. It runs on a 220V supply at up to 3000 rpm and suits handling, feed axes and general automation.

What power and torque does the 80mm servo deliver?

The 80 frame comes in three models: a 750 W model and two 1000 W models, with peak torque to about three times rated for acceleration. One 1000 W model runs to 3000 rpm for speed; the other runs to 2000 rpm with more torque. Rated torque and current per model are in the specification table above.

Why are there two 1kW models?

Both are 1 kW, but power is torque times speed, so at the same power you trade one for the other. The 3000 rpm model gives less torque for faster axes; the 2000 rpm model gives more torque for heavier, slower axes. Picking the right one means the motor delivers the torque your axis needs at the speed it runs. Tell us the load and speed and we will confirm which fits.

What is a 750W servo motor used for?

A 750 W servo is a common mid-size machine servo. It has more torque than a small 200 to 600 W servo, so it drives mid-size handling, feed axes, conveyors and packaging heads while staying compact and fast. In the 80 frame it is the entry model, with 1 kW models above it. Send your axis load and speed and we will confirm the fit.

Does the 80mm servo come with a matched drive?

Yes. Each 80mm servo ships with a matched servo drive, sized and tuned to the motor as a tested set, so commutation, gain and inertia matching are set before delivery. The drive runs position, speed and torque modes, with pulse and direction or bus communication depending on the model. You can also pair the motor with your own drive — ask us for the data you need.

Can I add a brake or a gearbox?

Yes to both. A power-off holding brake is available for vertical or inclined axes, and the braked version is longer — see the table for the dimension. A planetary gearbox is available to trade speed for torque on slower, higher-load axes. Specify the gear ratio when you ask for a quote.

What encoder does the 80mm servo use?

The 80mm servo uses a 17-bit absolute encoder for closed-loop feedback. Absolute means the axis knows its position the moment power comes on, so there is no homing routine after a power cycle — useful on machines that restart often. The encoder also closes the loop continuously, so the motor holds position under a changing load.

Can you build the 80mm servo to my drawing?

Yes. The 80mm servo is built for OEM integration, so the shaft diameter, length and keyway can be made to your drawing. We can add a brake, fit a gearbox, and change the connector and cable. Send your drawing or application and we will confirm what we can match.

80mm AC Servo Motor: 750W to 1kW for Mid-Size Automation

The 80mm servo motor is a mid-size permanent-magnet AC servo on an 80 mm (NEMA 32) flange. It runs 0.75 to 1 kW with 2.39 to 4.5 N·m of rated torque and about three times that as peak, on a 220V supply, and turns at up to 3000 rpm. It runs closed-loop on a 17-bit absolute encoder, so the axis knows its position on power-up and holds it under load. It is the step up from the 60mm frame, sized for mid-size handling, feed axes and general automation where a small servo runs short on torque.


Where the 80mm Servo Fits

The 80 frame is the mid-size industrial servo — more torque than the 60 frame, still compact and fast:

  • 0.75 to 1 kW and 2.39 to 4.5 N·m — the 750W and 1kW class for mid-size machines.
  • 17-bit absolute encoder — no homing routine, the axis keeps position through power cycles.
  • 80 mm frame — a straight step up from the 60mm servo motor when it runs short on torque.
  • 220V mains, IP65 sealing and Class F insulation for the factory floor.


Same Power, Different Speed and Torque

The 80 frame has two 1 kW models, and the difference is a useful thing to understand. Power is torque times speed, so at the same 1 kW you can have more speed with less torque, or more torque with less speed. The S10030 turns to 3000 rpm at 3.2 N·m for speed-led axes; the S10020 turns to 2000 rpm at 4.5 N·m for torque-led axes. Same power, matched to what the axis actually needs.

ModelPowerSpeedRated TorquePick When
80BSF-S07530750 W3000 rpm2.39 N·mFast axes at 750 W
80BSF-S100301 kW3000 rpm3.2 N·mSpeed-led 1 kW axes
80BSF-S100201 kW2000 rpm4.5 N·mTorque-led 1 kW axes

If the axis runs fast, take the 3000 rpm model; if it moves heavier load slower, take the 2000 rpm model. Send the load and speed and we will confirm which 1 kW build fits, or whether the 750W is enough.


Typical Applications

The 80mm servo suits mid-size axes that need more torque than a small servo, at speed:

  • Mid-size handling and transfer axes — more torque with fast, repeatable motion.
  • Feed axes on small and mid CNC — accurate positioning under cutting load.
  • Conveyors, indexers and rotary tables — steady torque on moderate loads.
  • Packaging and converting machinery — heavier heads and drives than a 60 frame.
  • Winders, tensioners and pumps — controlled torque at running speed.
  • Automation cells and assembly — mid-power positioning across the machine.


Drive and Customization

Each 80mm servo ships with a matched servo drive, sized and tuned to the motor as a tested set, so commutation, gain and inertia matching are set before delivery. The drive runs position, speed and torque modes, with pulse and direction or bus communication depending on the model. For heavier axes, the 110mm servo motor is the next frame up. Common changes: shaft diameter, length and keyway to your drawing, a power-off holding brake for vertical axes, a planetary gearbox, and connector and cable to suit. As a servo motor manufacturer, we test the motor and drive together and ship the encoder built in.
