Custom shaft, winding, lead wire, connector, and branding to your specification.
Hybrid servo stepper motors with built-in encoders for position feedback and anti-lost-step protection.
Standard samples ship in 3–5 days. Custom prototypes in 10–15 working days.
We build three main types of stepper motors — 2-phase, 3-phase, and closed loop. The 2-phase hybrid is our highest-volume product, covering NEMA 8 through NEMA 42. If your application needs lower vibration at higher speeds, go with 3-phase. If you need position feedback and anti-lost-step protection, the closed loop series is the right fit.

About Us facility Solutions CertificationsA hybrid stepper motor combines permanent magnet and variable reluctance structures in one rotor design. The rotor has a permanent magnet sandwiched between two toothed iron caps. This gives hybrid motors higher torque, better step accuracy, and finer step resolution than pure PM or VR stepper motors. Most industrial stepper motors on the market today are hybrid type, with standard step angles of 1.8° (200 steps/rev) or 0.9° (400 steps/rev).
We offer a comprehensive range of NEMA standard sizes for stepper motors, including NEMA 8, 11, 14, 17, 23, 24, 34, and 42, covering frame sizes from 20mm up to 110mm to meet diverse application requirements.
Yes, we offer full customization on motor shaft configurations, including keyway, flat cut, different shaft lengths and diameters, as well as custom winding parameters such as voltage, current, and resistance to match your specific driver and application needs.
The main difference lies in step angle and performance: 2-phase stepper motors have a standard 1.8° step angle, making them widely used in general applications, while 3-phase models feature a 1.2° step angle, offering smoother operation, lower vibration, and higher torque stability, especially suitable for heavy-duty and high-precision scenarios.
Custom sample lead time is typically 7 to 15 working days, depending on the complexity of your requirements, such as special shaft, winding, or other modifications; we can provide a more accurate timeline once we receive your detailed specifications.
We offer both separate stepper motors and matched motor driver packages; you can purchase motorsalone or select a complete driver-motor combo that is pre-tested and optimized for plug-and-playconvenience.

A stepper motor is a brushless DC electric motor that divides a full rotation into a fixed number of equal steps.Each step corresponds to a specific angle — typically 1.8° for a 200-step motor, or 0.9° for a 400-step motor. The motor moves one step for each electrical pulse it receives from the driver.
Inside the motor, the stator has multiple sets of coil windings. When the driver energizes these coils in a specific sequence, the magnetic field rotates in discrete increments, pulling the toothed rotor along one step at a time.Because each pulse produces a fixed angular movement, the controller knows the rotor position simply by counting pulses — no feedback sensor required. This is called open-loop control.
Stepper motors are the go-to choice when you need accurate positioning at a reasonable cost. They are used in 3D printers, CNC machines, medical pumps, packaging lines, and thousands of other applications worldwide.
Stepper motors are classified into three types based on rotor construction. Each type has different performance characteristics.
| Type | Rotor Structure | Step Angle | Torque | Typical Use |
|---|---|---|---|---|
| Variable Reluctance (VR) | Soft iron, no magnets | 5°–15° | Low | Simple positioning, legacy equipment |
| Permanent Magnet (PM) | Magnetized rotor | 7.5°–15° | Low–Medium | Valve control, HVAC dampers |
| Hybrid (HB) | PM + toothed iron caps | 0.9°–1.8° | High | CNC, 3D printing, automation, medical |
Hybrid stepper motors dominate the market, accounting for over 50% of global stepper motor sales. Theycombine the high torque of PM motors with the fine step resolution of VR motors. All stepper motorsmanufactured by Cymotorix are hybrid type.
Hybrid stepper motors are further divided by the number of electrical phases- most commonly 2-phase and 3-phase.
A 2-phase stepper motor has two sets of windings and a standard step angle of 1.8°. It is the most widely usedconfiguration in industrial and commercial equipment. Simple wiring, broad driver compatibility, and the widestrange of available frame sizes make it the default choice for most applications.
A 3-phase stepper motor has three sets of windings and a step angle of 1.2°. The finer step angle andoverlapping phase excitation produce smoother rotation, lower vibration, and better torque performance at mid-to-high speeds. The trade-off is a slightly higher cost and fewer available frame sizes.
• Choose 2-phase for general-purpose positioning, prototyping, and cost-sensitive projects.
• Choose 3-phase for applications where vibration, noise, or high-speed torque are critical concerns.
