DC 12-18V High Torque 775 Motor 4000-9000 rpm (Silver)

DC motoris any of a class of rotary electrical machines that converts direct current electrical energy into mechanical energy. The most common types rely on the forces produced by magnetic fields. Nearly all types of DC motors have some internal mechanism, either electro-mechanical or electronic, to periodically change the direction of current flow in part of the motor.775 MotorisHigh torque and high Energetic MotorisHigh quality diameter & low noise high torque Carbon brushmotor /long shaft high power dc motor forRobotics, drill, Fan, Pump, Hss Cutter, Generator, etc.
