How Do 2-Phase Hybrid Stepper Motors Work?
2-phase hybrid stepper motors combine the strengths of permanent magnet and variable reluctance technologies. This design uses an axially magnetized rotor and an electronically controlled stator to deliver accurate positioning and high step resolution.
These motors operate with pulsed DC current and divide rotation into fixed steps—typically 1.8° per step. When microstepping is applied, even finer motion control is possible. The hybrid configuration reduces resonance and improves operating stability, making them ideal for applications that demand long-term reliability and precision.
Key Advantages of 2-Phase Hybrid Stepper Motors
Compared to other stepper motor types, 2-phase hybrid motors offer:
- Higher torque at low speeds, ensuring better holding capability
- Smaller step angle, enabling smoother motion and precise control
- Improved energy efficiency, through optimized magnetic field utilization
- Reduced vibration and resonance, enhancing stability and service life
These benefits make them a robust solution for advanced automation systems requiring accurate and repeatable positioning.
