Brushless motor has some advantages as same as DC brush motor and remove brush and commutator to make no mechanical contacts. Magnets are rotate instead of motor coil.
Semiconductor (hall elements or hall IC) and driver board detect rotor position then changes current to the motor coil to run the brushless motor.
The most valuable characteristics of brushless motor are longer life, higher speed and less electrical noise because there are no electrical contacts even if motor driver is required.
Technical theory of brushless motor is as same as DC brush motor up to BLI and Law of left hand of Fleming then. The basic characteristics are same but just different rotate magnet or coil.
Brushless motor is classified two type from the view point of construction, one is inner rotor type (magnet is
located inside of coils) which has better mobility and the other is outer rotor (magnet is located outside of coils) which is better to make thinner type motors.
It is necessary to choose for each application from both types of brushless motors.
Citizen Micro develops many kinds of custom made brushless motors except standard ones.
Suitable gearhead is available for these brushless motors.
