NEMA17 Two Phase Hybrid Stepper Motor
This NEMA17 two-phase hybrid stepper motor uses two phases, or two sets of coils, to generate motion. The "hybrid" designation refers to the use of both a permanent magnet and electromagnetic coils in the motor design. NEMA17 refers to the size of the motor, with the "17" indicating that the motor has a 1.7-inch square faceplate and a 1/4-inch shaft. These motors are typically used in precision motion control applications such as 3D printing, CNC machines and Robotics.
Applications:
- 3D printing
- CNC machines
- Robotics
- Medical equipment
- Manufacturing
- Security systems
- Automation

1. What is a 2-phase stepper motor?
- A 2-phase stepper motor is a type of electric motor that converts electrical pulses into precise mechanical movements. It is called 2-phase because it uses two separate electrical windings or phases, which are activated in a specific sequence to rotate the shaft of the motor a specific number of degrees. This allows for precise control of the motor's movement, making it well-suited for applications that require precise positioning. When the two phases are energized in sequence, the motor will rotate a certain number of degrees per step, which is known as the step angle. Most 2-phase stepper motors have step angles of 1.8 or 0.9 degrees. The step angle is determined by the number of poles in the stator, which is the stationary part of the motor.
2. How does a hybrid stepper motor work?
- A hybrid stepper motor uses both a permanent magnet and electromagnetic coils in the rotor, and electromagnetic coils in the stator. The permanent magnet in the rotor provides a constant magnetic field, while the electromagnetic coils in the rotor and stator provide the variable magnetic field. This combination results in higher torque output and stable operation at low speeds.
