Type A motor:

Motor Diameter: :10 MM

Geared motor length: 20.2 MM (motor + gear box)

Output Shaft Diameter : 3 MM

Gearbox reduction ratio: 1:14.9 (approx.)

(About 298 pulse output shafts turn 360 degrees)

Step angle: The motor is 18 degrees and the output shaft is about 1.2 degrees.

Stepper motor: two-phase four-wire

(A+: yellow wire, A-: red wire. B+: blue wire, B-: white wire)

Phase resistance: 49.8 ohms (6V short circuit current 113MA)

Cable length: 320MM

Weight : 12g

Stepper motors need pulse frequency and driver to operate normally. This motor is suitable for low-frequency pulse signals, and its driving current is about 110 MA.
-----------------------------------------------------------
Type B motor:

Motor diameter: 15MM

Output gear outer diameter: 5.9 MM (10 teeth 0.5 module)

Gearbox reduction ratio: 1:232.8 (approximately)

(About 4656 pulse output shafts turn 360 degrees)

Step angle: The motor is 18 degrees and the output shaft is about 0.08 degrees.

Stepper motor: two-phase four-wire

(A+: blue wire, A-: red wire. B+: white wire, B-: yellow wire)

Phase resistance: 41.1 ohms (6V short circuit current 143MA)

Cable length: 350MM

Weight : 20g

Stepper motors need pulse frequency and driver to operate normally. This motor is suitable for low-frequency pulse signals, and its driving current is about 130 MA.

Micro stepping motor, all metal gears, exquisite workmanship. The stepping motor itself is a precision motor whose rotation angle is controlled by the pulse frequency. After passing through the gear box, the rotation angle is more subtle and the torque increases exponentially. This type of micro stepping motor is often used as a drive motor for monitoring equipment, communication equipment, precision instruments, etc.

The outer diameter of the A type motor is 10 MM, and the outer diameter of the B type motor is 15 MM.
