Abstract

The invention discloses a comprehensive leading-out circuit system of a direct-current permanent magnet brushless motor. The system comprises a PCB, and the PCB comprises an annular part and a bent part which are connected to form a 6-shaped structure; a Hall sensor circuit is arranged at the position, close to the inner diameter edge, of the annular part, a plastic extension socket terminal is arranged at the end, away from the annular part, of the bent part, and a connecting circuit from the plastic extension socket terminal to the Hall sensor circuit is arranged on the PCB. Two sets of welding openings are formed in the edge of the outer diameter of the annular part and used for welding motor windings respectively, one set of welding openings are close to the connecting position of theannular part and the bent part, an inserting piece terminal is arranged at the end, close to the annular part, of the bent part, and a connecting circuit from the inserting piece terminal to the nearest set of welding openings is arranged on the PCB. A Hall sensor signal output function and a motor power supply three-phase line connection function are integrated, so that the internal structure ofthe motor is simpler and more compact.

Description

technical field [0001] The invention belongs to the technical field of DC permanent magnet brushless motors, and in particular relates to a comprehensive lead-out circuit system of DC permanent magnet brushless motors. Background technique [0002] With the increasing demand for products powered by DC batteries in the market, the demand for DC permanent magnet brushless motors has begun to increase, and the use of various products has become common. The DC permanent magnet brushless motors currently on the market normally use the Hall position sensor to determine the rotor position relationship, and the Hall plate will be independently fixed near the magnetic circuit of the motor rotor. The Hall PCB board of this design is only used for the signal output of the Hall sensor, and the three-phase power line of the motor is led out separately; for some small-power and compact motors, the power three-phase lead Inconvenient to operate. Contents of the invention [0003] The p...
