The Zhong Hua Jiang 14HS2408 is a compact 35mm-frame, 2-phase hybrid stepper motor designed for precise incremental motion in CNC equipment, 3D printers, robotics, automation systems, positioning mechanisms and DIY motion-control projects. The motor uses a 1.8° full-step angle, providing 200 full steps per revolution before microstepping.
This model is specified at 4.4V and 0.8A per phase, with 5.5Ω phase resistance, 7.5mH inductance, Class B insulation and AWG26 lead wires. Its compact 35mm frame is suitable for applications that need controlled positioning and limited installation space.

The 1.8° step angle equals 200 full steps per revolution. When paired with a compatible microstepping driver, each full step can be electronically subdivided for smoother motion and reduced vibration. Actual positioning performance depends on the driver, mechanical transmission, load, acceleration, resonance and controller settings.

The table above reproduces the representative electrical data from the original product page. Products with special requirements can be discussed according to the customer's application, electrical specification and mechanical requirements.
Technical note: the original page lists holding torque as “Above 0.12 N·m” in the general specification, while the electrical specification table lists “12 mN·m.” Because these values are not equivalent, confirm the latest engineering datasheet before final motor selection or replacement.
| Insulation Level | Insulation Voltage | Insulation Resistance |
| Class B | 500V AC, 1 minute | Above 100MΩ |
| Class F | 500V AC, 1 minute | Above 100MΩ |
Motor insulation class describes the heat-resistance category of the winding insulation system. The 14HS2408 general specification identifies this 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 replacing an existing stepper motor or integrating the 14HS2408 into a new motion system, compare the flange dimensions, shaft dimensions, mounting-hole spacing, body length and available installation space with the mechanical drawing.
Connect the motor phases to the corresponding A and B outputs of a compatible bipolar stepper driver. Confirm the coil pairs before applying power, and disconnect power before changing the motor wiring.
The driver energizes the two motor phases in sequence to create controlled angular movement. Full-step, half-step and microstepping behavior depends on the selected driver and controller. Correct phase-current limiting is important for motor temperature, torque and service life.

These tolerances and operating conditions should be included in motion-system design. Available running torque generally decreases as speed increases, so motor selection should consider the complete speed-torque requirement rather than holding torque alone.
The 14HS2408 35mm hybrid stepper motor can be considered for compact CNC mechanisms, 3D printers, robotics, automation equipment, positioning stages, test fixtures, dispensing systems, camera or optical positioning devices and other applications that require repeatable incremental motion.
For correct selection, provide the required speed range, load torque, acceleration, duty cycle, load inertia, shaft load, mechanical dimensions, driver model, available supply voltage and quantity. This information helps determine whether the 14HS2408 or another motor configuration is appropriate.
A 35mm-frame hybrid stepper motor provides a compact mounting footprint while retaining the repeatable open-loop positioning characteristics of a 2-phase hybrid stepper design. It is useful when the machine has less installation space than applications designed around larger NEMA 17, NEMA 23 or NEMA 34 motors.
Huajiang was founded in 2000, beginning with CNC engraving spindle motor production and later expanding into variable-frequency drives, engraving machines and related CNC and motion-control products.

Certification requirements can vary by destination market and final equipment. For OEM or batch orders, request the current product documentation required for your project and confirm the applicable compliance standard before purchase.
The 14HS2408 uses a compact 35mm-class frame. In standard stepper-motor terminology, a 35mm square frame is commonly categorized as NEMA 14. Confirm the mechanical drawing before replacing a motor because mounting dimensions are more important than the product name alone.
A 1.8° step angle provides 200 full steps per revolution. A compatible microstepping driver can subdivide those full steps for smoother motion and finer commanded movement.
The original specification lists 4.4V rated voltage and 0.8A rated current. When using a current-controlled stepper driver, configure the phase-current limit according to the motor and driver requirements.
Use a bipolar 2-phase stepper driver that can regulate phase current around the motor's 0.8A rating and is compatible with the available power supply and controller. Confirm the driver's current range, supply-voltage range and microstep settings before installation.
Yes. A compatible microstepping driver can operate the motor at fractional electrical steps to reduce vibration and improve smoothness. The commanded microstep size should not be treated as guaranteed mechanical positioning accuracy under load.
The original page contains two different holding-torque entries: the general specification lists above 0.12 N·m, while the electrical specification table lists 12 mN·m. Confirm the latest engineering datasheet with Zhong Hua Jiang before using holding torque as a design value.
The source specification lists an allowable radial load of 21N and an allowable thrust load of 10N. Couplings, pulleys and lead-screw arrangements should be designed so the motor shaft is not subjected to loads above the specified limits.
Provide the current motor model, flange and shaft dimensions, load torque, target speed, acceleration, duty cycle, driver model, supply voltage, wiring requirements, required quantity and final application. These details help determine whether the 14HS2408 is suitable or whether a different motor is needed.
The original product information states that products with special requirements can be made according to customer requests. Contact the sales team with the required electrical, mechanical, lead-wire and quantity specifications for evaluation.
