Product description

The AK70-10 is a robotic actuator that combines a brushless DC motor, a 10:1 planetary gearbox, the driver and the encoder in a single unit. Its cross roller bearing makes it resistant to shock loads.

Key features

  • Cross roller bearing. Improves shock resistance and handles high radial and axial loads at the joint at the same time.
  • High integration. Motor, gearbox, driver and encoder are in one housing, with no extra boards or couplings.
  • Servo and MIT control modes. Switch between position, speed and torque control and the MIT hybrid mode.
  • 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 exoskeleton systems, quadruped robots, robot arms and joints working under dynamic loads.

Is it enough for your project?

The AK70-10 delivers 8.3 Nm continuous and 24.8 Nm peak torque. For example, a 2.5 kg load at the end of a 30 cm arm needs about 7.4 Nm of static torque (2.5 × 9.81 × 0.30). That load stays within the actuator's rated torque.

Because its cross roller bearing carries the radial and axial loads at the joint together, it is a common choice for quadruped robots and exoskeletons. Its 0.2 degree gearbox backlash also suits joints that need precise positioning.

How it compares to similar models

  • AK70-9 V3.0 KV60. At a similar rated torque (8.5 Nm) it gives higher peak torque (29.2 Nm) and is slightly lighter at 540 g. Its no-load speed is lower at 320 rpm.
  • AK80-9 V3.0 KV100. Faster, with 9 Nm rated torque and 570 rpm, and a flatter body at 38.5 mm tall.
  • AK60-6 V3.0 KV80. Lighter (380 g) but with about a third of the torque. It may be enough if the load at the end of the arm stays within a few kilograms.

Frequently asked questions

What is MIT mode?

A hybrid control mode in which position, speed and torque targets are sent in a single command together with stiffness and damping gains. The joint behaves like a spring and damper, which legged robots use to soften ground contact.

Do I have to tune the PID by hand?

No. Automatic identification in the PC software sets the parameters with one click.

Is the driver included?

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

How much gearbox backlash is there?

According to the manufacturer, 0.2 degrees.

In the box

  • AK70-10 KV100 robotic actuator with integrated driver
  • Power and CAN communication cable
  • Serial communication cable
  • Certificate of conformity

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.
