Understanding High Torque Brushed Motor Technology
A high torque brushed motor is a DC motor that uses mechanical brushes and a commutator to transfer electrical current to the rotating armature.
The interaction between the magnetic field and armature current generates rotational force and torque.
Core Operating Principle
The basic operating structure includes:
- Rotor (armature)
- Stator magnets
- Carbon brushes
- Commutator
- Shaft and bearings
As electrical current passes through the armature windings, electromagnetic force creates rotational movement.
The brush and commutator system continuously switches current direction to maintain rotation.
