Dual stepper motor, also known as double-shaft stepper motor, features extended output shafts on both ends. It is a special structured stepper drive component. The dual stepper motor delivers rotary power from both sides simultaneously. It is widely used in bidirectional synchronous transmission, roller pair mechanisms, flipping stages, dual-station automation devices and small winding machines. It eliminates extra gear reversing structure and simplifies mechanical design, solving the limitation that single-shaft stepper motors cannot output power from two directions at the same time.
Dual-End Coaxial Shaft, Bidirectional Power Output
The dual stepper motor has output shafts on both front and rear ends. One single motor provides synchronous rotation on two sides. The dual stepper motor can drive two sets of actuators at once to simplify transmission layout and reduce component count.
Integrated Shaft Machining for High Synchronization
The dual stepper motor adopts one-piece shaft machining with high concentricity on both shafts. There is no angular deviation between two rotating ends. The dual stepper motor ensures consistent bilateral movement to meet synchronous positioning requirements of dual-station linked machines.
Standard Flange Size for Easy Replacement
The dual stepper motor keeps regular NEMA flange dimension with the same mounting holes as conventional stepper motors. The dual stepper motor can directly replace single-shaft stepper motors without retooling your original mounting bracket.
One Motor for Dual-Side Drive to Cut Component Cost
The dual stepper motor replaces two separate drive units, removing intermediate transmission parts like couplings and timing pulleys. Using the dual stepper motor shortens BOM and reduces procurement and assembly cost of the whole machine.
Compact Structure to Save Mounting Space
Instead of installing two motors side by side, one dual stepper motor handles bidirectional driving. The dual stepper motor greatly reduces the horizontal footprint, ideal for compact automation machine design.
Customizable Shaft Options on Both Ends
The dual stepper motor supports custom shaft diameter, keyway and shaft length on each side. Options include smooth shaft on one end and flat shaft on the other. The dual stepper motor matches different load structures for personalized mechanical assembly.

Q: Can both shafts of dual stepper motor output torque at the same time?
A: Yes. Both ends of the dual stepper motor can output torque synchronously. The total torque of dual stepper motor is the rated holding torque of the motor itself, and the load should be reasonably distributed on two shafts.
Q: Is the rotation direction the same for two shafts of dual stepper motor?
A: The two shafts of dual stepper motor rotate in the same direction. If reverse rotation on one side is needed, you need to add external reversing mechanism for the dual stepper motor.
Q: Can dual stepper motor be fitted with brake or gearbox?
A: Yes. We can install electromagnetic brake or planetary gearbox on either shaft of the dual stepper motor according to your machine requirements.
Q: Can dual stepper motor use standard stepper driver?
A: Yes. The electrical parameters of dual stepper motor are same as ordinary single-shaft stepper motor. Standard stepper driver can directly control the dual stepper motor.
Q: Can I order dual stepper motor with different shaft lengths on two sides?
A: Yes. Custom different shaft lengths for each end of dual stepper motor is available. We can machine unequal shaft length according to your mechanical design requirements of dual stepper motor.
