Brushless Motors

Question 1

Brushless Motor Uses?

Answer 1

Power tools, Electric Cars, Remote Control Vehicles, Aircrafts, Vacuums, Respirators, Computer Printers, Wind Turbines, 3d Printers .

Question 2

How do Brushless Motors Work?

Answer 2

The electrical current passes through coils that are arranged within a fixed magnetic field. The current generates magnetic fields in the coils; this causes the coil assembly to rotate.

Question 3

Difference between a brushed motor and a brushless motor?

Answer 3

A brushed motor has brushes sending electricity to the commutator causing it to spin. Brushless motors replace the mechanical commutation function with electrical control.

Question 4

Problems with Brushless Motors?

Answer 4

Overheating
Power loss
Difficulty starting
Failure due to wear and tear
Short circuits

Question 5

Advantages of Brushless Motors?

Answer 5

Efficient
Low Maintenance
Less noise
Higher torque to weight ratio
Longer lifespan.
