Description

Technical Parameters

A hollow stepper motor (also known as a through-bore or hollow-shaft stepper motor) is a type of stepper motor with a central, open hole that runs through the entire length of its rotor and stator.

A hollow stepper motor has many advantages such as Space Savings: Creates a very compact and streamlined drive system by removing external couplings and reducing the overall assembly length; Simplified Assembly: Makes the integration of shafts, screws, and optical elements much more straightforward; Clean Cable Management: Wires, hoses, or fiber optics can be routed through the center, protecting them from tight bends and tangling in rotating systems etc.

Typical application

Hollow stepper motors are ideal for applications requiring a clean and compact path for components to pass through the axis of rotation e.g. machinery, medical devices, AGV, RGV, and other logistic equipment.

FAQ

Q: How do I choose the motor size?

A: Please refer to the product model variant data above and the product drawing that is included.

Q: Are there inspection reports that include rated power, rating torque, maximum radial bearing force, maximum radial axial force, etc.

A: We do offer sample and serial inspection reports that include all of the key performance information.

Q: Do you produce the goods that are being offered?

A: Yes, our own skilled staff develops, manufactures, assembles, and tests the items.

Q: Can you modify the product to meet specific customer requirements, such as motor or axis dimensions?

A: We are able to offer our clients customized products.

Q: What are biggest benefits of Hollow stepper motor?

A: The hollow stepper motor solves mechanical integration challenges that are difficult or impossible with standard motors. It's not that the motor itself is more powerful, but that it enables a cleaner, more robust, and more compact overall system design.
