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.
