Inventory Brushless motor with drive external rotor, power about 10W at 12V
【Applicable voltage】DC 5-20V
[No-load speed] 970-5200 rpm
This motor is estimated to be the spindle motor of the old tape recorder. The silicone grease between the drive chip and the heat sink has dried up. It can be replaced if conditions permit, and it can be used normally without replacement.
The motor needs two voltages for power supply, between 5V and the driving voltage 5-20V. The higher the driving voltage, the higher the speed and the higher the output power. The output speed is more than 900 rpm at 5V, 3000 rpm at 12V, and more than 5000 rpm at 20V. The motor stator has 24 poles, the output torque is relatively large and stable, and it can run stably at a very low speed with stalled rotors.
The forward and reverse terminals are connected to the 5V positive pole for forward rotation, and the negative pole for reverse rotation. It is also forward rotation when suspended, but it is easy to be interfered by weak external signals, so it is recommended to be connected to the circuit. When the motor is running, it can be switched between forward and reverse at any time . For other pin definitions, please refer to the baby picture.
