What are the pros and cons of a brushed motor?
Brushed Motor Pros
Two wire control
Some are rebuildable for extended life
Low cost of construction
Simple and inexpensive control
No controller is required for fixed speeds
Operates in extreme environments due to lack of electronics
Brushed Motor Cons
Periodic maintenance is required
Speed/torque is moderately flat. At higher speeds, brush friction increases, thus reducing useful torque
Poor heat dissipation due to internal rotor contsruction
Higher rotor inertia limits the dynamic characteristics
Lower speed range due to mechanical limitations on the brushes
Brush arcing will generate noise causing electrical magnetic interference (EMI)
Brushless Motor Pros
Electronic commutation based on position sensors vs mechanical switch for brushed
Less maintenance due to absence of brushes
Speed/Torque- flat, enables operation at all speeds with rated load
High efficiency, no voltage drop across brushes
High output power to size ratio.
Reduced size due to superior thermal characteristics. Because the windings are connected to the case the heat disipation is better
Higher speed range - no mechanical limitation imposed by brushes/commutator
Low electric noise generation (EMI)
Brushless Motor Cons
Higher cost of construction
Control is complex and expensive
Electric controller(ESC) is required to keep the motor running which is sometimes more expensive than the motor.
