Tips: Which types of stepper motor is divided into?

Stepper motor is divided into three types: permanent magnet stepper motor (PM), variable reluctance stepper motor (VR) and hybrid stepper motor (HB).

1. PM stepper motor is generally 2-phase, with small torque and volume, its stepping angle is generally 7.5° or 15°.
2. VR stepper motor is generally 3-phase; high torque output can be realized; the stepping angle is generally 1.5, but the noise and vibration is large. The rotor magnetic circuit of VR stepper motor is made of soft magnetic materials. There is multi-phase exciting winding on the rotor. The torque is generated by taking advantage of the change in magnetic conductance.
3. HB stepper motor, indicating mixing the advantages of PM and VR, is divided into 2-phase, 3-phase and 5-phase. The stepping angle of 2-phase is generally 1.8°, that of 3-phase 1.2° and that of 5-phase is 0.72°. It is mostly widely applied.

0.9° and 1.8° Hybrid Stepper Motors

1.8° Step Angle,The motors are directly compatible with the stepper motor drive boards and also drive either motor (if required) in the half step mode i.e. 0.9° per step resulting in higher resolution, greater performance stability and faster stepping rates. Direction, velocity, acceleration/deceleration can be controlled by a stepper motor controller.,Applying the correct electrical pulse sequence to the windings of the stepper motor results in a 1.8° step angle rotation of the spindle (i.e. 200 steps per revolution). When correctly loaded and driven these motors will produce discrete output steps. The number of steps and speed of rotation are determined by the number of pulses and frequency of the input signal. This provides an ideal method for speed and position control. The motors are directly compatible with stepper motor drive boards.

Computer controlled stepper motors are a type of motion-control positioning system. They are typically digitally controlled as part of an open loop system for use in holding or positioning applications.

In the field of lasers and optics they are frequently used in precision positioning equipment such as linear actuators, linear stages, rotation stages, goniometers, and mirror mounts. Other uses are in packaging machinery, and positioning of valve pilot stages for fluid control systems.

Commercially, stepper motors are used in floppy disk drives, flatbed scanners, computer printers, plotters, slot machines, image scanners, compact disc drives, intelligent lighting, camera lenses, CNC machines and, more recently, in 3D printers.
