Description
Technical field
The utility model belongs to finite angle technical field of motors, is specifically related to a kind of engine electric igniter finite angle motor.
Background technology
Engine electric igniter requires that motor has following characteristics usually:
1, when electrical power, motor belt motor nominal load, moves to open position, exports and opens signal; When motor power-off, motor returns initial position, exports cut-off signals.
2, service time (motor exports from being energized to the time of signal of opening) of motor and turn-off time (motor is from power-off to the time of output cut-off signals) are in prescribed limit.
3, there is high workload reliability and environmental suitability.
Traditional dynamo-electric igniter motor is made up of direct current torque motor and position indicator.Motor by stator, rotor and brush three part form.Rotor is by after rotor iron core laminated, and in rotor, embed armature winding by certain rule, inserted by commutator segment in rotor, one end forms commutator segment, and the other end welds with winding tail end.Brush is made up of brush plate and brush holder, and brush plate is welded by spring leaf and brush head.Brush is fixed on stator side, and brush plate is connected across commutation sheet surface.Stator is formed by stator yoke and bonding magnetic steel.Position indicator adopts conductive ring structure, is connected on motor stator by location hole.Electric machine structure is complicated, and production cost is higher, and under the condition of long-time vibration, the output signal of motor can accurately not reflect the operating state of motor.
Utility model content
The utility model solves the deficiencies in the prior art, provides a kind of simple and compact for structure, engine electric igniter finite angle motor that long working life, cost are low.
The technical scheme that the utility model adopts is: comprise motor body, motor body center is provided with stator, stator center is provided with rotor, rotor center is provided with motor shaft, motor body one end is provided with end cap, the other end is provided with bonnet, the relative bonnet afterbody of motor body is provided with spring, spring deviates from bonnet one end and is provided with lead-out wire, finite angle motor also comprises position indicator, position indicator is made up of slip ring assembly and brush assembly of electric, slip ring assembly and brush assembly of electric relative rotor center are laid, slip ring assembly is connected mutually with rotor, brush assembly of electric is connected mutually with stator, slip ring assembly is made up of slip ring frame and slip ring, and slip ring to be sleeved in slip ring frame in round empty cavity, brush assembly of electric is made up of brush holder and brush, and brush is equidistantly arranged around brush holder radial direction, and brush indicates the brush silk of open position and scram position to form by two groups respectively.
The advantage that the utility model compared with prior art has and effect: overcome the defect that Traditional DC motor causes useful life lower due to the friction of brush and commutator, eliminate the parts such as brush and commutator of Traditional DC torque motor, electric machine structure is simply compact, long working life, cost are low, improves machine operation reliability and environmental suitability.
