BRUSHLESS DC MOTOR.
Brushless DC motors offer advantages such as smaller size, lighter weight, and controlled speed through electronic speed controllers. They come in outer rotor and inner rotor types, each with its own set of advantages and disadvantages. Brushless motors have three wires compared to two in brushed motors, generating less RF interference and eliminating constant arcing. Explore the differences and characteristics of brushless and brushed DC motors for a better understanding in academic labs.

BRUSHLESS DC MOTOR GT ECE ACADEMIC LAB SLIDES BY MARK ORBAN
WHAT IS A BRUSHLESS MOTOR A synchronous motor using a switching power supply Controlled via an electronic speed controller (ESC) circuit Smaller and lighter than equivalent brushed DC motors
OUTER ROTOR TYPE Advantages: Easy to obtain large torque. Speed is stable during constant rotation. Disadvantages: The rotor is large (the motion is slow). The outside rotor requires appropriate safety measures. Source: https://www.nidec.com/en/technology/capability/brushless/
INNER ROTOR TYPE Advantages: The rotor is small and can respond quickly. The coil is located on the outside and the level of heat dissipation is high. Disadvantages: Difficult to obtain large torque. Magnets can be damaged by centrifugal force. Source: https://www.nidec.com/en/technology/capability/brushless/
BRUSHLESS VS BRUSHED Brushless has three wires vs two for brushed Brushless doesn't have the constant arcing of the brushed commutator Generates less RF interference than brushed DC motors
