RobotDigg are professional manufacturer of Hollow Shaft Stepper Motors from China, ranges of our hollow shaft stepping motors are Nema8, Nema11, Nema14, Nema17 and Nema34, these would be for design flexibility and great selections of your own bespoke ballscrew or leadscrew.
Hollow Shaft Stepping Motors with precise request on the internal diameter are for bespoke ballscrew or leadscrew, RobotDigg produce Nema17 6mm large bore, Nema23 11mm, 12mm large bore and Nema34 14mm, 15mm large bore with 0.003mm/3um Accuracy, which are very precise BORE as Hollow Shaft. Besides hollow shaft stepper, we produce ground and bespoke leadscrew for non-captive linear stepper motors, with POM nuts or Anti-backlash Nuts for different linear motion applications, we also accept client's request on Teflon Coating for leadscrew. Hollow Shaft Stepper Motor with bespoke ballscrew or leadscrew Coupler/Coupling Saving, will increase the mechanical concentricity, more compact and reliablity.
Hollow Shaft Stepper Motor in another way promise increased design flexibility by allowing cables or other medias to be routed through the motor shaft, effectively reducing the space required of the motor solution. Some applications are not requiring a Accuracy on the Bore of the Hollow Shaft Stepper Motor of this kind, it's usually for air, light and even cables to be through. This way hollow shaft stepping motors are well suited for use in telecommunications devices, the replacement of pneumatic cylinders and general factory automation applications, and with the ability to provide rapid prototypes and enhanced customization, RobotDigg can reduce the design cycle of an application while maximizing product output. Hollow shaft stepping motor is useful in beam line applications where a clearance hole at the centerline is vital to proper machine operation. Raster scanning, hologram generating, laser scanning, filter adjustments and instrument insertions for X-ray, electron, proton, optical light beams and commercial 3D printers have been deployed. Hollow shaft stepper motors are also useful in cable, fiber optic and other continuous process manufacturing equipment where high strength and light weight glass or graphite fibers are wound into complex coverings as the core passes through the center of the motor. Similar applications include: constant thickness spray, flame coatings, bead impingement and electro-deposition on the core material. Hollow motors allow liquids or gases to be pumped through their hollow center, making them ideal for automated spray machines, and water and ink jet controls.
•Hollow Shaft or threaded shaft step motor
•Nema8, Nema11, Nema14, Nema17, Nema23 and Nema34
•Bespoke or ground leadscrew
•POM nut, brass or anti-backlash nuts
•Normal treatment Trapezoidal, Acme standard Leadscrew or Teflon Coating for longer life time and smooth linear motion
•Customized length and resolution, leadscrew diameters.
* It adopts the method without coupling by assembling derectly Ball-screw or TM-screw etc.
* No coupling, low vibration, low noise.
* Economical price.
* Best suited for applications with small sized equipment.
* Compact design and light weight with high accuracy, speed and torque.
These kind of linear stepper motor or step motor linear actuator have a hollow shaft or threaded shaft, which allows them to be used as a linear actuator with Bespoke Leadscrew or Ground Leadscrew. Brass nut, POM nut or Anti-backlash Nuts. Stainless Steel Acme standard Trapezoidal Leadscrew with normal treatment or Telfon Coating treatment for anti-corrosion or special long run and smooth applications. As the motor runs, it moves along the leadscrew or ballscrew at a specific rate of 1cm per 5 or so full rotations. These are good choice for linear motion where precision and repeatability are important.
