Product description
The AK45-10 V3.0 is a compact robotic actuator that combines the motor, a 10:1 planetary gearbox and the driver in a single 53 mm housing. The key change in V3.0 is the dual encoder design. Single-turn absolute position is kept even after power loss, so the joint does not need to be homed at startup.
Key features
- Dual encoders. Two 16-bit magnetic encoders (MT6835) sit on the motor side and the output side, giving position readings with better noise immunity.
- High torque density. It delivers 7 Nm peak torque from 262 g, a torque to weight ratio of 26.9 Nm/kg.
- Servo and MIT control modes. Switch between position, speed and torque control and the MIT hybrid mode. The PC software identifies PID parameters with one click.
- Built-in protection. Overcurrent, overvoltage, undervoltage and overtemperature protection are inside the housing.
- Plug and play wiring. Power and CAN share one XT30 connector, which reduces wiring errors and assembly time.
Applications
Typical applications include humanoid robot wrist and hand joints, small robot arms, compact automation mechanisms and R&D projects where losing position at startup is not acceptable.
Is it enough for your project?
The AK45-10 V3.0 delivers 2.5 Nm continuous and 7 Nm peak torque. 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.
It runs on 24 V, with a no-load speed of 180 rpm and a rated speed of 120 rpm. The output bearing has a dynamic load rating of 2,810 N and a static load rating of 2,760 N. If you need a faster, lighter joint the AK40-10 V3.0 may be a better fit, and if you need more torque, the AK45-36 V3.0.
How it compares to similar models
- AK45-10 KV75. The previous version with the same torque figures. It has a single encoder, weighs 260 g, is 43 mm long and does not keep its position after power loss.
- AK40-10 V3.0 KV170. With the same 10:1 reduction it gives 1.3 Nm rated torque, is lighter at 190 g and much faster at 435 rpm.
- AK45-36 V3.0 KV80. With a 36:1 reduction it gives 8 Nm rated and 24 Nm peak torque, in return its no-load speed is 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 AK45-10?
V3.0 has dual encoders and remembers its single-turn absolute position after power loss. The previous version has a single encoder and has to find its reference point at every startup. Torque figures are the same, and the V3.0 housing is 2.2 mm longer.
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.
