Product description

The AK80-8 is an integrated robotic actuator with an 8:1 planetary gearbox and dual encoders. The output shaft encoder keeps the position within one turn.

Key features

  • Dual encoder. Position is read both at the motor input and at the output shaft. This makes gearbox backlash visible and improves positioning accuracy.
  • Single-turn position memory. The output shaft encoder remembers the position and reduces the need for re-homing at power-up.
  • Selectable force and servo mode. The control approach can be changed to suit the application.
  • Built-in protection. Overcurrent, overvoltage, undervoltage and overtemperature protection are inside the housing.

Applications

Typical applications include exoskeleton joints, robot arms, AGV drive systems and collaborative robots.

Is it enough for your project?

The AK80-8 delivers 10 Nm continuous and 25 Nm peak torque. For example, a 3 kg load at the end of a 30 cm arm needs about 8.8 Nm of static torque (3 × 9.81 × 0.30). That load stays within the actuator's rated torque.

The second encoder on the output shaft remembers the position within one turn, so the joint does not need to be homed at power-up. This shortens commissioning in exoskeletons and AGV drives. Its 360 rpm no-load speed is enough for medium-speed joints, and if you need faster swings the AK80-9 V3.0 may be a better fit.

How it compares to similar models

  • AK80-9 V3.0 KV100. At the same diameter it gives 9 Nm rated torque, is faster at 570 rpm and lighter at 490 g. It has a single encoder.
  • AK70-10 KV100. Gives 8.3 Nm rated and 24.8 Nm peak torque, is faster at 480 rpm and weighs 621 g.
  • AKE80-8 KV30. At the same weight it gives 12 Nm rated torque, but it has no driver board and needs an external driver.

Frequently asked questions

What is the dual encoder for?

There is a 14-bit magnetic encoder on the motor side and a 15-bit one at the output shaft. The output encoder reads the real joint angle independently of gearbox backlash and remembers the position within one turn.

How much gearbox backlash is there?

According to the manufacturer, 0.38 degrees.

Can it be turned by hand?

Yes. Backdrive torque is about 0.75 Nm, so the joint can be moved by hand when unpowered.

Is the driver included?

Yes. The driver board, dual encoder and planetary gearbox are inside the housing. The box includes power, CAN and serial communication cables.

In the box

Frequently asked questions

The most common questions about motor selection, delivery and technical support.

Is the product in stock and when is it dispatched?

Our products ship from our own warehouse in Turkey. Your order is dispatched within 3 business days. Current stock status is shown on this page.

Which motor fits my project? Can you help me choose?

Yes. Tell us the torque, speed and supply voltage you need, and we will find the right series together. You can also compare using the specifications table on this page and the filters on the category page.

  • For high torque at low speed, the AK, AKE and AKH series with gearbox
  • For direct drive and low inertia, the frameless RI and RO series
  • For cameras and stabilization systems, the GL series
Are the products genuine and under warranty?

Robotizma is an official CubeMars distributor. Every product we sell is genuine and covered by the manufacturer's warranty.

Where can I find the datasheet and mounting dimensions?

The Specifications section on this page lists rated torque, peak torque, KV, no-load speed, weight and outer dimensions. If you need the detailed datasheet, CAD file or driver documentation, ask our technical team.

Do you offer corporate sales, quotes and invoices?

We sell to universities, industry and R&D projects. For volume pricing and a formal quote, fill in the Request a quote form on this page and our team will reply with price and delivery details.

Which driver and communication can I use with the motor?

In the AK and AKH series actuators the driver board is built into the motor and communicates over CAN. The AKE series and the frameless RI and RO series motors need an external FOC driver. The R-Link and S-Link interfaces are for setup and debugging, and we can support you during installation.
