How to customized bldc motor?The stator of brushless DC motor is the coil winding armature and the rotor is the permanent magnet.If only to motor with fixed dc current, the motor can only produce the constant magnetic field, the motor can't turn, only real-time detecting the rotor position, according to the position of the rotor to the motors of different mutually to corresponding current, make the rotating magnetic field of the stator produce uniform direction changes, motor can follow magnetic field rotation.
For the convenience of description, the center tap of the coil of the motor stator is connected to the motor POWER supply, and the end points of each phase are connected to the POWER tube. When the position sensor is switched on, the G pole of the POWER tube is connected to 12V, the POWER tube is switched on, and the corresponding phase coil is energized.Since all three as the rotation of the rotor position sensor will, in turn, conduction, makes the corresponding phase winding and electricity, in turn to the stator magnetic field direction also constantly change, motor rotor followed rolling, this is the basic principle of rotating brushless dc motor, detecting of rotor position, in order to the same electricity, make the direction of the magnetic field of the stator produce continuous evenly.
