Product description

The AKE60-8 is a quasi-direct drive robotic actuator developed for exoskeleton applications. The planetary gear and motor are joined in one housing.

Key features

  • Quasi-direct drive. A low-ratio planetary gear is combined with the motor, so force feedback is felt directly.
  • Low backlash. Because gear backlash is low, position repeatability is high.
  • Mounts from both sides. The actuator can be fixed from either side, which gives flexibility in joint layout.
  • Modular design. The same interface can be used across different joints.

Applications

Typical applications include exoskeleton joints, rehabilitation devices, collaborative robot arms and mechanisms that work in contact with people.

Is it enough for your project?

The AKE60-8 is a quasi-direct drive actuator delivering 5 Nm continuous and 12.5 Nm peak torque from a 260 g body. For example, a 1.8 kg load at the end of a 25 cm arm needs about 4.4 Nm of static torque (1.8 × 9.81 × 0.25). That load stays within the actuator's rated torque.

In quasi-direct drive the reduction is kept low (8:1). The joint stays compliant to external forces, and force feedback can be read from motor current. At 25 mm tall and with a 24 V operating voltage it suits exoskeleton wrists and elbows and wearable rehabilitation devices.

How it compares to similar models

  • AKE80-8 KV30. The next model up in the same series, with 12 Nm rated and 30 Nm peak torque. It weighs 570 g and runs on 48 V.
  • AK45-10 KV75. At the same weight (260 g) it gives 2.5 Nm rated torque, but its driver board is inside the housing.
  • AK60-6 V3.0 KV80. Gives 3 Nm rated and 9 Nm peak torque with an integrated driver board. It weighs 380 g.

Frequently asked questions

Is the driver included?

No. The AKE series has no integrated driver board, and the actuator runs with an external FOC driver. Our technical team can help you choose a driver.

What voltage does it run on?

Its rated voltage is 24 V. At that voltage its no-load speed is 240 rpm.

How much gearbox backlash is there?

According to the manufacturer, 9 arcminutes, or about 0.15 degrees.

How is position read?

The Ø6 × 2.5 mm sensor magnet in the box is fitted to the end of the shaft, and position is read from it by the magnetic encoder on the driver side.

In the box

  • AKE60-8 KV80 robotic actuator (driver board not included)
  • Ø6 × 2.5 mm sensor magnet

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.
