มอเตอร์เกียร์ DC Motor 6-12V พร้อม AB Phase Encoder 110 rpm/300 rpm TT motor

Description:

Model: TT motor

Working voltage: DC 6V-12V 

Speed:  [ Metal 110rpm / Plastic 300rpm ]

Encoder board description:

Board size: 26mm*22mm*1.2mm

Terminal pin definition:

• G: Hall power supply negative pole
• H1: Hall H1 output signal, square wave
• H2: Hall H2 output signal, square wave
• V: Hall power supply positive pole
• M+:Motor power supply positive pole
• M-: motor power supply negative

Remarks:
1. The voltage between V-G is determined according to the power supply voltage of the microcontroller used, generally 3.3V or 5V is used.
2. The frequency of the square wave output from H1 and H2 is related to the speed of the motor and the number of poles of the magnet used.
3. The voltage between M+ and M- is determined according to the motor voltage used.

Principle of operation：

1.motor speed measurement: Hall sensors can sense the N and S poles of the magnetic disk, we use the Hall of the S pole, that is, every time the Hall sensor senses the S of the magnetic disk, the Hall output will output a high level: sensing the N pole of the magnetic disk, the Hall output output a low level. When the motor rotates continuously, the Hall output outputs a square wave. The rotational speed of the motor can be known from the period T of the output square wave. Suppose we are using a magnetic disk with P-pair poles. Measured square wave period is T. Measure the motor speed: n = 60/PT

2. motor forward and reverse measurement: the circuit in two different positions placed in two Hall sensors, when the motor steering is different at the same time, the two Hall output square wave is not the same.
