At present, the market demand of NEMA 23 hybrid stepper motor is still very large. It is widely used in carving machine, laser machine, CNC machine, textile machinery, medical equipment, measuring equipment, electronic processing equipment, packaging machinery and other automation equipment and instruments. NEMA 23 hybrid stepper motor is a kind of stepping motor which combines the advantages of permanent magnet and reactive. It is divided into two-phase, three-phase and five phase, two-phase step angle is generally 1.8 degrees, three-phase step angle is generally 1.2 degrees, and five phase step angle is generally 0.72 degrees.
The rotor of NEMA 23 hybrid stepper motor is magnetic, so the torque generated by the same stator current is greater than that of reactive stepping motor, and its step angle is usually small. Therefore, the economic CNC machine tools generally need NEMA 23 hybrid stepper motor drive. However, the hybrid rotor has complex structure and large inertia, and its rapidity is lower than that of reactive stepping motor.
Characteristics of NEMA 23 hybrid stepper motor:
1. High output torque and high speed;
2. The motor has low heating, low noise and high efficiency;
3. High speed stop stable and fast, no zero speed oscillation, stable operation, low vibration noise;
4. Fast response, suitable for frequent start and stop occasions.
The NEMA 23 hybrid stepper motor developed and manufactured by Dewo motor is based on the industry's advanced magnetic circuit design scheme. In terms of material selection, it is made of high-temperature permanent magnet and high-quality cold-rolled steel sheet, Japan NMB or NSK bearing is selected, and the surface of the motor is sprayed with plastic or sealed with aluminum shell. This series of NEMA 23 hybrid stepper motors have the characteristics of high output torque, low temperature rise, low noise and low vibration, and high reliability and stability. The motor runs smoothly without obvious oscillation zone, which can meet the use of different working conditions in automation industry.
