how are mainly composed of brushless dc motor rotor motor, dongguan eppo unmanned aerial vehicle (uav) motor, converts electrical energy into mechanical energy. Operation of the brushless dc motor by electronic commutation circuit (Brushless dc motor, with dongguan model aircraft brushless motor, brushless dc motor using electronic means reversing. To make a BLDC spin motors must be according to certain order to the stator current, so we need to know the position of the rotor according to the current order to give the corresponding stator coil electricity. The position of the stator is composed of hall sensors embedded in the stator. Usually arrange three hall sensors around the rotation of the rotor path. No matter when, as long as the rotor's magnetic pole over the hall element, according to the rotor current magnetic polarity hall element will be output corresponding to high or low level, so as long as according to the three level produced by the hall element sequence can determine the position of the rotor current, and the corresponding electricity) was carried out on the stator winding, thus greatly reduce the electric spark interference with remote radio equipment, also reduced the noise. It one end fixed to the frame lever motor frame, a fixed screw, through the downward thrust produced by the rotation. Different size, load of the frame, need to cooperate with different specifications, power of motor.
（2)Basic principle of
every time the reversing has a set of windings in positive electricity; A second group of the same electricity; The third group without power. Magnetic field of permanent magnet rotor and stator sheet steel produced by magnetic field interaction creates a torque, in theory, when the Angle between the two magnetic field is 90 & deg; Would produce the maximum torque, torque when the two magnetic fields overlap to 0, the dongguan brushless motor, in order to make the rotor rotation, then the
need in order to change the stator magnetic field, as the rotor's magnetic field has been chasing the stator magnetic field. The typical & other; Step six current commutation & throughout; Sequence diagram shows the stator winding current order.
