The Zhong Hua Jiang 8HS4406 is a 2-phase hybrid stepper motor designed for precise incremental motion in compact CNC, automation, robotics, positioning and DIY motion-control systems. The motor uses a 1.8° full-step angle, corresponding to 200 full steps per revolution, and is specified at 3.3V and 0.6A.
With a listed holding torque above 0.026 N·m, Class B insulation, AWG26 UL1061 leads and a compact motor structure, this NEMA 20 stepper motor is intended for applications where repeatable positioning, controlled low-speed motion and compact installation are important. For best performance, match the stepper driver current setting, supply voltage, acceleration profile and mechanical load to the motor and machine requirements.

The values above are the specifications shown for the representative 8HS4406 product on this page. Special configurations can be discussed according to application requirements. When selecting a driver, prioritize the motor's rated phase current and the driver's current-control capability rather than selecting only by the motor's rated voltage.
| Insulation Level | Insulation Voltage | Insulation Resistance |
| Class B | 500V AC, 1 minute | Above 100 MΩ |
| Class F | 500V AC, 1 minute | Above 100 MΩ |
Motor insulation class describes the heat-resistance category of the insulation system. The source material lists A, E, B, F and H temperature classes. The 8HS4406 general specification on this page identifies the motor as Class B.
| Temperature Class of Insulation | A Level | E Level | B Level | F Level | H Level |
| Maximum Allowable Temperature (°C) | 105 | 120 | 130 | 155 | 180 |
| Winding Temperature Rise Limit (K) | 60 | 75 | 80 | 100 | 125 |
| Performance Reference Temperature (°C) | 80 | 95 | 100 | 120 | 145 |
Before integrating the motor into a CNC axis, linear stage, robot mechanism or custom machine, verify the flange, shaft, mounting-hole pattern, available installation space and coupling dimensions against the mechanical drawing.
Connect the two motor phases to the corresponding A and B outputs of a compatible bipolar stepper driver according to the wiring diagram. Confirm coil pairs before applying power, and switch off the driver before changing motor wiring.
The stepper driver energizes the two phases in sequence to create controlled angular movement. Full-step, half-step and microstepping behavior depends on the driver and controller. Correct current limiting is important for torque, temperature rise and motor life.

These tolerances and operating conditions should be considered during motion-system design. Actual available torque decreases as speed increases, so the motor should be evaluated together with the driver, supply voltage, load inertia, acceleration, transmission ratio and required operating speed.
The 8HS4406 2-phase hybrid stepper motor can be considered for compact motion-control tasks such as small CNC mechanisms, desktop automation, robotics, positioning stages, dispensing equipment, camera or optical positioning, test equipment, educational machines and custom DIY motion systems where the required torque and load remain within the motor's operating capability.
For selection, provide the required speed range, load torque, acceleration, duty cycle, shaft load, mounting dimensions, driver model and available supply voltage. This allows the motor, driver current setting and mechanical transmission to be matched more accurately.

Certification requirements can vary by destination market and final equipment. For OEM or batch orders, request the current product documentation needed for your application and confirm the required compliance standard before purchase.
It is intended for compact motion-control applications that require repeatable angular positioning, including small CNC mechanisms, automation equipment, robotics, positioning stages, test fixtures and other low-load motion systems that match the motor's torque and operating conditions.
A 1.8° full-step motor has 200 full steps per revolution because 360° divided by 1.8° equals 200. A microstepping driver can subdivide these full steps for smoother motion.
The specifications on this page list a rated voltage of 3.3V and a rated current of 0.6A. When using a current-controlled stepper driver, set the phase current according to the motor and driver instructions.
The source specification lists holding torque above 0.026 N·m, equivalent to 26 mN·m. Available running torque will be lower than holding torque and normally decreases as motor speed increases.
Use a bipolar 2-phase stepper driver that can regulate phase current around the motor's 0.6A rating and is compatible with your controller and supply voltage. Confirm the driver's minimum and maximum current range before wiring the motor.
Yes, when connected to a compatible microstepping driver. Microstepping can reduce vibration and make motion smoother, although the commanded microstep size should not be treated as guaranteed mechanical positioning accuracy under load.
The product specification identifies the motor as Class B insulation. The source insulation table lists 130°C as the maximum allowable temperature for Class B insulation, while the operating technology conditions specify a maximum temperature rise of 80°C.
Provide the motor model, mounting dimensions, shaft dimensions, load torque, target speed, acceleration, duty cycle, driver model, supply voltage, wiring requirements, quantity and final application. This helps confirm whether the 8HS4406 is suitable or whether a different stepper motor is required.
