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.

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.

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
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.
