The hybrid meaning of hybrid stepper motors

1.Introduction to hybrid stepper motors
The hybrid stepper motor is a motor that combines the working principles of permanent magnet stepper motors and variable reluctance motors. It combines the advantages of the two motors and has the characteristics of simple stepper motor structure, high torque, high precision, low noise, and easy control. At the same time, it takes into account the low inertia, high speed, self-starting, and strong stability of variable reluctance motors. Therefore, hybrid stepper motors have been widely used in the field of industrial automation.

2.The hybrid meaning of hybrid stepper motors
The "hybrid" in hybrid stepper motor refers to the combination or combination of the characteristics of variable reluctance stepper motor and permanent magnet stepper motor. Hybrid stepper motor, also known as HB stepper motor, is a type of stepper motor that combines the advantages of variable reluctance stepper motor (VR) and permanent magnet stepper motor (PM). Under non-overload conditions, the speed and stop position of this motor depend only on the frequency and number of pulses of the pulse signal, and are not affected by load changes. When the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle in the set direction. The design of the hybrid stepper motor makes it excel in output torque, dynamic performance and step angle, while maintaining structural complexity and relatively high cost. This motor is usually divided into two-phase, three-phase and five-phase series to meet the needs of different applications.

3.Advantages of hybrid stepper motors
1.High torque: The hybrid stepper motor adopts the structure of variable reluctance motors, which can maintain a high torque at high speeds.
2.High precision: The hybrid stepper motor adopts the structure of permanent magnet stepper motor, which has the advantages of high precision, low error, low jitter, etc., and is widely used in occasions with high precision requirements.
3.High stability: When the hybrid stepper motor is running at low speed, the rotor can remain very stable and has strong anti-interference.
4.Low vibration: The hybrid stepper motor adopts a combination of permanent magnet stepper motor and variable reluctance motor, which reduces vibration and noise.

4.Summary
In general, the hybrid stepper motor combines the characteristics of permanent magnet stepper motor and variable reluctance motor, has the advantages of both motors, and makes up for the shortcomings of its single motor, making it widely used in the field of industrial automation.
