Product description

The AK45-10 is a robotic actuator that offers high power density in a compact body. It combines a 10:1 planetary gearbox, the driver and the encoder in one housing.

Key features

  • High power density. Strong output for its light structure.
  • 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 humanoid robot wrist and hand joints, small robot arms, compact automation mechanisms and R&D projects where weight is critical.

Is it enough for your project?

The AK45-10 delivers 2.5 Nm continuous and 7 Nm peak torque from a 260 g body. For example, a 1 kg load at the end of a 20 cm arm needs about 2 Nm of static torque (1 × 9.81 × 0.20). That load stays within the actuator's rated torque.

At 53 mm in diameter and with a 24 V operating voltage it suits humanoid robot wrists and hands, small robot arms and desktop robots. Its no-load speed is 180 rpm. If you need a faster small joint the AK40-10 may be a better fit, and if you need more torque, the AK45-36.

How it compares to similar models

  • AK40-10 KV170. With the same 10:1 reduction it gives 1.3 Nm rated torque, is lighter at 185 g and twice as fast at 435 rpm.
  • AK45-36 KV80. With a 36:1 reduction it gives 8 Nm rated torque, in return its no-load speed is 52 rpm.
  • AK60-6 V3.0 KV80. Gives 3 Nm rated and 9 Nm peak torque, weighs 380 g and runs on 48 V.

Frequently asked questions

Is the driver included?

Yes. The driver board, a 14-bit magnetic encoder and the planetary gearbox are inside the housing. The box includes a power and CAN cable and a serial communication cable.

What voltage does it run on?

Its rated voltage is 24 V. At that voltage its no-load speed is 180 rpm.

How much gearbox backlash is there?

According to the manufacturer, 18 arcminutes, or about 0.3 degrees.

Can it be turned by hand?

Yes. Backdrive torque is about 0.1 Nm, so the joint moves easily by hand when unpowered.

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.
