Mini MT78 motor 1-3 V 12000 rpm for Raspberry Pi Arduino cars

Product description

MT78 1-3V mini motor is a miniature brushed DC motor, ideal for projects using microcontrollers-for Arduino, Raspberry Pi, ESP32, and ESP8266. The device is powered by a voltage in the range of 1V to 3V. No-load current draw is 0.6A at 2V. The motor has compact dimensions of 38 mm × 20 mm and reaches a speed of 7400 rpm, making it an excellent choice for projects that need small yet powerful drives.

Tips and how it works

• The key element of the motor is the commutator, responsible for reversing the voltage polarity so the rotor keeps turning continuously in the same direction.
• Supply voltage is applied to the commutator segments, which together with the rotor windings produces a magnetic field.
• This field interacts with the stator magnetic field, created by slotless permanent magnets.
