NEMA 23 hybrid stepper motoris designed by combining the advantages of permanent magnet and reactive stepper motor. It is divided into two phase, three phase and five phase, two phase stepping Angle is generally 1.8 degrees, three phase stepping Angle is generally 1.2 degrees, and five phase stepping Angle is generally 0.72 degrees.

The rotor of the NEMA 23 hybrid stepper motor itself is magnetic, so the torque generated in the same stator current is greater than the reaction stepping motor, and the step Angle is usually smaller, therefore, economic CNC machine tools generally need to use the hybrid stepping motor drive. But the structure of the mixed rotor is more complex, the rotor inertia is large, its rapidity is lower than that of the reaction stepping motor.

The NEMA 23 hybrid stepper motor is divided into two phase, three phase and five phase: two phase stepping Angle is generally 1.8 degrees and five phase stepping Angle is generally 0.72 degrees, the hybrid stepping motor with the number of phase (the number of energized winding) increase, the stepping Angle decreases, the accuracy is improved, this stepping motor is the most widely used.

The NEMA 23 hybrid stepper motor combines the advantages of reactive and permanent magnet stepper motors: the polar logarithm is equal to the number of rotor teeth, which can be changed in a wide range according to the need; The winding inductance varies little with the rotor position, which is easy to realize the optimal operation control. Axial magnetizing magnetic circuit, the use of high magnetic energy product of new permanent magnet materials, is conducive to the improvement of motor performance; Rotor magnetic steel provides excitation; There is no noticeable oscillation throughout the operating region.
