AW60HS Series — NEMA 24 Stepper Motor with Hollow Shaft
The AW60HS series is Apexwell's NEMA 24 (60mm) hybrid stepper motor line built around a through-bore hollow shaft, letting cables, optical fibers, pneumatic lines, or a pass-through mechanism run directly through the rotor axis instead of routing around the motor. Across four body lengths from 56mm to 100mm, holding torque scales from 1.25 N·m to 2.8 N·m, and each model is available in either 4-wire (bipolar) or 6-wire (center-tap) configuration, positioning this frame size between the AW57HS and AW86HS hollow-shaft lines.

Wiring
Like the AW42HS and AW57HS, the AW60HS is available in both 4-wire (bipolar) and 6-wire (center-tap) configurations on the same body lengths, so it can drop into either a bipolar or unipolar driver setup without a different motor SKU.
Typical Applications
With a through-bore hollow shaft and torque up to 2.8 N·m, the AW60HS series fits industrial rotary tables and turntables needing cable or slip-ring-free pass-through, robotic base and turret joints, coiling and winding machinery, and cable-management-sensitive rotary equipment where the AW57HS's torque range fits but a slightly higher-current motor stack is needed.
Why Choose the AW60HS Series
A hollow shaft removes the need for a separate cable pass-through mechanism or slip ring — wiring, fiber, or a secondary shaft can run straight through the motor's rotational axis, simplifying the mechanical design around it, especially at industrial torque levels where routing cable externally becomes harder to manage. The 4-wire/6-wire choice lets one motor selection match either driver type, and four body lengths let a product line scale holding torque over 2x (1.25–2.8 N·m) on the same mounting footprint. Custom shaft bore diameter and connector configurations are available on request.
We can customize the electrical parameters of the motor and geometric dimensions such as the motor output shaft size according to customer requirements. Accessories including pulleys, eccentric gearboxes, planetary gearboxes and encoders can also be added.
