Unlike the brush of direct current, brilliant direct -current electric motors usually use a constant magnet on the rotor and windings on the stature. Electronic controls are used to change the polarity of current in windings. Rotor position control sensors fix its position and transfer this information back to the electronic control unit. Brightless DC engines are more related synchronous motors of alternating current than to the brushing engines of direct current.
Brighting engine of direct current
Advantages of brilliant direct current engines over a direct current brush engines
Higher efficiency
Great reliability
Lack of mechanical wear wear
Quiet
There is no sparks
Reduced cooling requirements
Reducing electromagnetic radiation
