Summary of the invention
For overcoming the above-mentioned defective of prior art, the invention provides a kind of direct current brushless motor Hall device sensor, at a high speed through out-of-date, the hall device sensing realizes minimum error to this device in magnetic field, reduces electric energy loss.Simultaneously, having simplified the hall device circuit connects.
The present invention realizes that the technical scheme of above-mentioned purpose is: direct current brushless motor Hall device sensor, its hall device circumferentially are distributed on the circuit board, and the hall device output wiring terminal is connected with circuit, and lead is exported from circuit board one end; Circuit board is fixed on the end face or main shaft of motor stator one side, and hall device is aimed at stator winding lead output magazine position; Near circuit board is outer annular permanent magnet or soft magnetic bodies are installed, the annular permanent magnet magnetic pole is corresponding with the rotor permanent magnetism magnetic pole, and is fixed on the rotor end cap; The circuit board lead links to each other with the power supply circuits of stator winding by the output of main shaft wire guide.
Operation principle of the present invention compared with prior art, its useful technique effect is: in the time of near hall device is passed through in annular permanent magnet magnetic field on the rotor rotation electric motor end cap, voltage of hall device output that order has been switched on, make the conducting of stator winding power supply circuits, give corresponding stator winding power supply, produce and the identical or opposite magnetic field of rotor permanent magnetism magnetic pole polarity, the repulsion rotor rotation, the pushing motor that moves in circles remains in operation.Find that under study for action during each particle process magnetic line of force of Hall, hall device sensing sensitivity relative linear velocity has the limit.Each particle angular speed of running object equates, the different linear velocity differences of diameter, and diameter is more little, and linear velocity is more little.According to this principle, designed direct current brushless motor Hall device sensor, promptly hall device is located on the end face of motor minor diameter.This device sensitivity is relatively very high, and when motor speed during at 3000r/min, sensing error is close to zero.Therefore be reflected on the motor, its no-load current is normal.
