Description
Technical field
The utility model is related to a kind of direct current generator, more particularly to a kind of electronic commutation DC start motor, belongs to and starts
Machine starts motor.
Background technology
At present, Civil Aviation Engine starting motor is generally brushed DC motor, not only loosely organized, volume is big, weight is heavy,
The defects such as complex structure, and carbon brush part easily weares and teares, must often change, it is impossible to meet the requirement of modern Development of Civil Aviation.
The content of the invention
For drawbacks described above present in prior art, the utility model aims to provide a kind of small volume, lightweight, structure
The convenient electronic commutation DC start motor of compact, speed governing.
To achieve these goals, the utility model uses following technical scheme：It includes being turned by stator winding, permanent magnet
The motor that son, reversing arrangement are constituted；Three position sensors are evenly equipped with PM rotor, the reversing arrangement is by controlling
The inverter of the drive circuit and drive circuit connection of device and controller connection is constituted；Wherein, controller by with each institute
State the Hall circuit of position sensor connection and the PWM circuit of Hall circuit connection and PWM circuit connection
Logic circuit constitute, inverter is made up of the first bridge arm for being connected with drive circuit respectively, the second bridge arm, the 3rd bridge arm, the
The corresponding connection of the A phase windings of one bridge arm, the second bridge arm, the 3rd bridge arm and stator winding, B phase windings, C phase windings；Each institute's rheme
Sensor is put to be connected with Hall circuit respectively.
Also include voltage-stabilized power supply, three ends that the voltage-stabilized power supply is connected by DC/DC power modules and the DC/DC power modules
Voltage-stablizer is constituted.
Compared with the prior art, the utility model therefore, it is possible to utilize to be arranged on by adopting the above-described technical solution, turn
Position of the individual phase winding relative to rotor permanent magnet magnetic field on each position sensor senses stator on son, and it is defeated to controller
Out position signal, controller is according to predetermined logical program by drive circuit to the power switch crystal for constituting inverter leg
Pipe sends instruction, commutating the current to corresponding armature winding；As rotor is rotated, position sensor constantly sends position and refers to
Order, causes the continuous once electrification of armature winding, constantly changes "on" position, so that being flowed in the coil-conductor of a certain magnetic pole lower end
The sense of current crossed is constant all the time；Electric energy is changed into mechanical energy, starting aircraft engine so as to reach.
The utility model small volume, lightweight, simple structure, speed governing convenience, steady performance.
