Product description

The AK80-64 is the highest-reduction model in the series. Its 64:1 planetary gearbox delivers high peak torque in demanding dynamic tasks.

Key features

  • 64:1 reduction. The highest torque output in the series, suited to heavy joints.
  • Dual control mode. Switch between force control and servo control.
  • Automatic PID identification. Parameters are identified with one click in the PC software, which largely removes the need for manual tuning.
  • Built-in protection. Overcurrent, overvoltage, undervoltage and overtemperature protection are inside the housing.

Applications

Typical applications include heavy-load robot joints, large robot arms, industrial automation mechanisms and R&D projects that need high torque.

Is it enough for your project?

With 48 Nm continuous and 120 Nm peak torque, the AK80-64 is the most powerful model in the AK series. For example, an 8 kg load at the end of a 50 cm arm needs about 39 Nm of static torque (8 × 9.81 × 0.50). That load stays within the actuator's rated torque.

Because of the 64:1 reduction, no-load speed is 75 rpm, or about 450 degrees per second. It suits places where torque matters more than speed, such as the shoulders of heavy-load robot arms, lifting mechanisms and knee joints. Its torque-to-weight ratio of 141 Nm per kilogram stands out in designs that want the same torque from a lighter body.

How it compares to similar models

  • AK10-9 V3.0 KV60. Faster, with 18 Nm rated torque and 320 rpm, and weighs 940 g.
  • AKH70-48 V1.0 KV41. More powerful, with 74 Nm rated and 222 Nm peak torque, and has a hollow shaft for cables. In return it weighs 1,396 g and is slower at 35 rpm.
  • AKE90-8 KV35. A quasi-direct drive (QDD) alternative with 55 Nm rated torque and 210 rpm, weighing 1,400 g.

Frequently asked questions

Can it do force control?

Yes. You can switch between force control and servo control.

How much gearbox backlash is there?

According to the manufacturer, 0.18 degrees.

Is the driver included?

Yes. The driver board is inside the housing. The box includes a power cable, a CAN cable and a serial communication cable.

What else do I need for setup?

The R-Link interface is used for parameter setup, and for multi-axis setups the Driver Board and Wiring Package products can be used.

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.
