Description
Technical field
The utility model relates to a kind of integral type brushless motors.
Background technique
In many fields, for example, space industry, the position precision control of guided missile Vertical Launch is generally adjusted using zero-bit
Device carries out, and principle is to drive potentiometric rotation using the low speed rotation of motor, is moved by potentiometer output valve
The accurate control of mechanism position, to realize missile position gesture stability, but at present used in motor low-speed stability and can
It is poor by property, affect the service precision of zero-bit regulating device.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of integral type brushless motor, the integral type is brushless electricity
Machine using feedback mechanism realizes the electronic commutation function of motor by integrated design, improve motor low-speed stability and
Reliability.
The utility model is achieved by the following technical programs.
A kind of integral type brushless motor including casing and is separately fixed at the reduction gearbox and controller of casing two sides, institute
It states and is provided with stator, rotor and bearing in casing, the stator and the rotor after bearing support by being fixed on casing, institute
Rotor is stated to connect that reduction gearbox is driven to rotate with reduction gearbox；Trigger member, the trigger member and control are additionally provided in the casing
Device connection processed, the controller are connect with stator and rotor respectively, and the trigger member triggers when the rotor rotates and then exports letter
Number to controller, controller controls the commutation function of the integral type brushless motor.
Further, the stator uses slotless configuration.
Further, the reduction gearbox uses profile modified gear.
Further, the rotor is outer-rotor structure.
Further, the trigger member is hall position sensor.
Further, the trigger member is close to the stator.
The utility model has the beneficial effects that: (1) use integrated design, improve motor low-speed stability and can
By property；(2) stator uses slotless configuration, can eliminate the cogging torque of stator, to improve the running stability of rotor, slows down
Case uses high-precision profile modified gear, and rotor is outer-rotor structure, improves the output torque of motor.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
Integral type brushless motor as shown in Figure 1 including casing 1 and is separately fixed at 2 Hes of reduction gearbox of 1 two sides of casing
Controller 3, stator 4, rotor 5 and bearing 6 are provided in casing 1, and stator 4 and rotor 5 are fixed on casing after supporting by bearing 6
On 1, rotor 5 connect that reduction gearbox 2 is driven to rotate with reduction gearbox 2；Touching is provided on the position of stator 4 in casing 1
Outbox 7, trigger member 7 are connect with controller 3, and controller 3 is connect with stator 4, the triggering output letter when rotor 5 rotates of trigger member 7
Number to controller 3, controller 3 controls the commutation function of the integral type brushless motor, allows entire motor normal
Rotation.
After applying voltage to controller 3, rotor 5 rotates, to trigger trigger member 7, trigger member 7 exports feedback signal to control
Device 1 processed, to realize the electronic commutation of motor in turn.When rotor 5 rotates, reduction gearbox 2 can be driven to rotate, to export revolving speed
And zero-bit regulatory function is realized in torque.
