[Motor Basics] Brush motor structure, rotation principle, power generation principle, short brake, characteristics

Brush motors are a type of motor that are widely used in a variety of applications, including models (RC cars and drones) and home appliances. To understand how this motor works, the ROHM website below first provides a detailed explanation of its structure. In particular, it provides a detailed explanation of the function of the two-pole magnet and three-slot coil that enable the motor to operate.
We also explain in an easy-to-understand way how brush motors generate power and how the short brakes of the brushes control rotation. We also delve deeply into the characteristics of brush motors, such as the relationship between power supply voltage and torque and theoretical analysis using equivalent circuits.
