The working principle of the motor
Working principle of the motor
1, the HALL IC of magnetic field strength and deformation to determine polarity, the output control signal to control the motor fan ( The morning a cooling fan) Operation, when the 9141 come nearest to the permanent magnet rotor S pole, and under the effect of magnetic field, the hall hall voltage components, after a series of signal processing, eventually 9141 responsible output low potential, PUN3 conduction ( 9141 PIN2 output high voltage) , through the red coil L1 current I1 in stator level 4, respectively, the relative magnetic pole, P1 - 年代,P2 - N，P3- 年代,P4 - N, and the rotor ( Magnetic stripe) Level 4, magnetic effect, promote the rotor rotate counterclockwise. Wenling city tong chi auto air conditioning manufacturing co. , LTD. , specializing in the production of cooling fans.
2, 9141914 1 responsible when rotor S very left, PIN2 DRIVER has the time by the responsible together, PIN2 output high potential, avoid red coil L1 and L2 yellow work depend on the turn at the same time, the inertia of the rotor was moved to 9141 N, hall hall voltage components, after a series of signal processing, eventually PIN2 output low potential, 9141 ( 9141 responsible output high potential) , through the yellow L2 coil current I2 in stator quadrupole, produce relatively pole PIN - respectively N, p - S，P3- N, P4 - S and rotor ( Magnetic stripe) Quadrupole magnetic effect, promote the rotor rotate counterclockwise, since 9141, according to a magnetic field intensity and magnetic induction switch constantly 9141 pin2, responsible for DRIVER take turns to alternately conduction, finally realizes the heat exchange control of the motor, the motor is kept in the rotation.
