In medical devices the priority is not high torque but precision and low vibration. In surgical assistance systems, imaging equipment and rehabilitation devices, the motor is expected to run smoothly and predictably.
For medical devices we recommend models from the AK and RI series. Rated torque runs from 0.57 Nm to 18 Nm and peak torque from 1.63 Nm to 53 Nm.
Frameless RI models save space because they are built into the device's own mechanics and allow a slim design. Integrated AK models speed up installation.
In medical applications, certification and safety requirements vary by project. If you share your device's requirements with us, we can evaluate the right model together.
The most common questions when comparing products in this category.
Rated torque is what the motor can deliver continuously without overheating, so size your system to it. Peak torque is the upper limit it can withstand for short periods. Look at peak torque for starts and impacts, and rated torque for continuous operation.
KV is the number of revolutions per volt. A low KV means more torque and less speed, and a high KV the opposite. With the same frame, the KV choice sets the speed and torque balance of your application.
A gearbox increases torque and reduces speed. Applications that need high torque at low speed, like a legged robot joint, favor a high ratio (36:1, 48:1), and those that need fast response favor a low ratio (6:1, 9:1). If you are not sure, send us your target torque and speed.
In integrated actuators (AK, AKH) the driver, encoder and gearbox are inside the motor, and they run over CAN straight out of the box. The AKE series combines motor and gearbox and uses an external driver. Frameless motors (RI, RO) are just a rotor and stator that you build into your own mechanics, and they need an external driver. Choose frameless for tight spaces or custom designs, and integrated for quick installation.
In the filter panel you can narrow down by series, gear ratio, peak torque, KV, no-load speed, weight and price. On desktop the panel sits to the left of the list, and on mobile it opens with the Filter button. Products without a value for a filter drop out when you apply it, so we recommend starting broad and narrowing step by step.
