Didn’t find your size? Ask us about custom options
In addition to the standard sizes of the IR-F series, we also have other form factors and dimensions (e.g. D77 and D125) in development or production. Don’t see the size you’re looking for? Get in touch, there’s a good chance we already have what you need.
If needed, we can also develop a completely application-specific motor in collaboration with you. This way a fully integrated solution can be realized with optimized costs and efficiency that increases your competitiveness.
Even if your project requires only moderate annual quantities, we can provide a tailored solution developed in close collaboration with you.
Also available: Outrunner Torque Motors
We also offer Outrunner Torque Motors for applications requiring higher torque at lower rotational speeds. These motors deliver exceptional performance by positioning the rotor outside the stator.
This design allows for increased torque density, making outrunners ideal for applications demanding significant torque in compact spaces. Outrunner motors are particularly suited for industries where low-speed operation with high torque is critical.
Our MI-F outrunner torque motors series come in four build volumes (40 mm, 110 mm, 250 mm, and 485 mm), each available in three heights (25 mm, 50 mm, and 75 mm), with continues torque spanning from 0.97 Nm to 1207 Nm.
FAQ IR-F 52
In short: A torque motor is a direct-drive electric motor optimized for high torque and precise control rather than high speed.
Here are the key points:
-
Direct drive operation: Torque motors are often used without gears, belts, or transmissions. They connect directly to the load, which reduces mechanical complexity and increases precision.
-
High torque density: They are built to generate a large amount of torque relative to their size.
-
Smooth and precise motion: Because of their design, torque motors offer low cogging (jerky movement) and can hold positions very accurately, making them ideal for applications that require precision.
-
Continuous stall operation: Unlike standard motors, torque motors can run continuously at very low speeds while still delivering torque, which is especially useful in robotics, machine tools, and automation systems
The IR-F 52 series is designed with a compact frameless construction, low cogging, and high torque density, making it ideal for integration into space-constrained applications like robotics and precision automation.
Depending on the stack height, the IR-F 52 offers continuous torque ranging from 0.22 Nm to 0.97 Nm, with peak torque values up to 1.44 Nm.
The IR-F 52 is commonly used in robotics, factory automation, and precision machinery, where small size and smooth, reliable performance are critical.
We offer three standard inrunner motor sizes, but our capabilities go beyond that.
Behind the scenes, we’re developing and producing additional form factors. If your preferred size isn’t listed among the standard options, we encourage you to contact us. Chances are that we already have a suitable solution in the works.
Or we can develop a custom fit together with you.
Yes. In addition to our standard product range, we can engineer motors to match your requirements.
Adjustments can be made in dimensions, torque output, speed characteristics, or interface options.
If needed, we can also develop a completely application-specific motor in collaboration with you. Our engineering and R&D teams will guide you through the entire process to ensure you receive a cost-effective and optimized solution.
