Product description
The AK40-10 V3.0 is a lightweight robotic actuator that packs a brushless motor, a 10:1 planetary gearbox and the driver board into a single module 53 mm in diameter and 40.2 mm long. At 190 g and 435 rpm no-load speed, it is the lightest and fastest member of the compact AK V3.0 group (AK40-10, AK45-10 and AK45-36). Thanks to its dual encoder design, single-turn absolute position is kept after power loss, so the joint does not need homing at startup.
Key features
- Dual encoders. Two 16-bit magnetic encoders (MT6835) sit on the motor input and the output side, giving more stable position readings under interference.
- Built for speed. It reaches 370 rpm rated speed and 435 rpm no-load speed, a good match for light joints that need a quick response.
- Low mass. It produces 4.1 Nm peak torque from 190 g, a torque to weight ratio of 21.5 Nm/kg.
- Servo and MIT control modes. Position, speed and torque control plus the MIT hybrid mode are supported. The software identifies PID parameters with one click.
- Built-in protection and plug and play wiring. Overcurrent, over and undervoltage and overtemperature protection are inside the housing. Power and CAN share one XT30 connector.
Applications
Typical uses include humanoid robot neck, wrist and finger joints that carry light loads but must move quickly, lightweight robot arms, and education and R&D prototypes.
Is it enough for your project?
The AK40-10 V3.0 delivers 1.3 Nm continuous and 4.1 Nm peak torque. For example, a 0.5 kg load at the end of a 15 cm arm needs about 0.74 Nm of static torque (0.5 × 9.81 × 0.15). That load stays within the actuator's rated torque.
It runs on 24 V with a maximum continuous power of 50 W. The output bearing has a dynamic load rating of 2,810 N and a static load rating of 2,760 N. If you need to carry the same load on a longer arm, the AK45-10 V3.0 with 2.5 Nm rated torque may be a better fit.
How it compares to similar models
- AK40-10 KV170. The previous version with the same torque and speed figures. It has a single encoder, weighs 185 g, is 37 mm long and does not keep its position after power loss.
- AK45-10 V3.0 KV75. With the same 10:1 reduction it gives 2.5 Nm rated and 7 Nm peak torque, weighs 262 g and has a no-load speed of 180 rpm.
- AK45-36 V3.0 KV80. With a 36:1 reduction it gives 8 Nm rated torque, weighs 349 g and has a no-load speed of 52 rpm.
Frequently asked questions
Is the driver included?
Yes. The driver board, both encoders and the planetary gearbox are inside the housing. The box includes a power and CAN cable and a serial communication cable.
How is it different from the previous AK40-10?
V3.0 has dual encoders and remembers its single-turn absolute position after power loss. Torque and speed figures are the same. The V3.0 is 5 g heavier and 3.2 mm longer than the previous version.
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 0.06 Nm, so the joint turns very 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.
