These are hollow frameless motors with low cogging design consisting of a stator and rotor, designed for use in collaborative robots and products with built-in structures.
The lineup includes four different sizes with different outputs, which can be used in a wide range of applications by selecting a product suitable for the structure and size of the customer's product.
IA-IB Series (Hollow Frameless Motors)
Wide range of applications
The frameless structure and four sizes allow a high degree of freedom in design to match the shape, structure, size, etc. of the customer's product, making it suitable for a wide range of applications.
Smaller and lighter products
Can be built in as is. This leads to further downsizing and weight reduction of your products.
Energy-saving design
Highly efficient magnetic circuit design that saves energy with less energy loss even when used for long periods of time.
Smooth movement
Low cogging design contributes to smooth robot motion.
We have a lineup of four products from which you can select the optimum diameter and output for each joint of the cooperating robot.
*IA series (stator) and IB series (rotor) are sold as a set.
