Product specifications:

This 2-phase 4-wire stepper motor with planetary gearbox is disassembled and produced by Zhawei,

However, due to the fact that steppers also belong to the brushless category and are used to control motors, and their workmanship is very good, they are still very new and have practical value.

The characteristics are as follows:

1: Net weight of 108g, stepper+planetary reduction, and other mechanical components are included. The stepper motor and gearbox are both very good, especially the gearbox, planetary reduction, and reduction ratio have not been determined yet

2: 2-phase 4-wire stepper with planetary reducer, stepper with Hall feedback (direction+speed pulse)

3: 2-phase 4-wire stepper, with a phase resistance of 7.3 ohms. From the perspective of phase resistance, it belongs to relatively high current, and it is possible to use constant current stepper drive.

4: Exquisite workmanship. The wiring is sealed with transparent resin (not easy to break), the motor, gearbox, and screws are sealed with glue, and the planetary reducer output shaft is equipped with ball bearings. The components have a delicate texture and precise processing. There are several similar models, and the workmanship of this Zawai product is good.

5: According to feedback from an insider buyer, the stepping angle of the stepper motor is 18 degrees, and the gearbox is a 3-stage planetary reducer, all of which are metal gears with 45 teeth on the outer ring and 9 teeth on the middle wheel. The three-stage reduction ratio is (1+45/9) * (1+45/9) * (1+45/9)=216, and the workmanship is quite exquisite.
