The advantage is that motor stator subassembly and rotor subassembly carry out physics keeps apart, prevents that the liquid in the pivot gets into the sleeve from getting into stator module, can work under adverse circumstances. Simultaneously, the great problem of air gap of motor has been solved.
Description
Technical field
This utility model relates to technical field of motors, particularly a kind of valve limited angle torque motor。
Background technology
Common dc motor is used for one direction and rotates continuously, but in valve applications occasion, owing to needs move back and forth, and the locus of motor rotation is required, and conventional DC Motor Control can be caused complicated。
Existing limited angle torque motor mostly is some and has only to make the applications of reciprocally swinging such as infrared imaging, optical mechaical scanning etc.。
The limited angle torque motor of traditional form such as moving-coil type or moving-magnetic type structure。Basic structure is as shown in Figure 3 and Figure 4。Moving-coil type limited angle torque motor winding is wound on rotor, and magnet steel is on stator, and winding draws difficulty, and winding heat radiation is bad。Moving-magnetic type limited angle torque motor winding is on stator, and magnet steel is on rotor, and the structure of rotor is complicated, is unfavorable for the dynamic response of rotor, and stator winding makes air gap increase in air gap。
Conventional finite corner torque motor does not generally do encapsulation process when using。
Summary of the invention
For the deficiency of above conventional DC motor and traditional form limited angle torque motor, this practicality is new
Type provides a kind of valve limited angle torque motor, this utility model is in cylindrical casing, one cylindrical sleeve is set, between casing and sleeve, being cylindrical stator assembly, be cylindrical rotor assembly at bushing core, cylindrical casing one end is spacing end cap, encapsulation process is done, it is prevented that enter the liquid in sleeve along rotating shaft and enter stator module between sleeve and spacing end cap；The upper and lower symmetry of rotor core in described rotor assembly has platform, upper and lower platform is pasted magnet steel respectively, and the magnet steel polarity on upper and lower platform is identical, and length is different。
The roller end at described rotor core center, is fixed with a steel ball, rotating shaft other end limited location pin in off center position。
Having groove between the tooth of the stator core in described stator module, around stator winding in groove, have little groove in crown end, in the end of winding equipped with sensor cluster, stator winding arrangement constitutes the winding method of a positive and a negative。
The utility model has the advantages that, motor stator component and rotor assembly are physically separated, it is prevented that enter the liquid in sleeve along rotating shaft and enter stator module, it is possible to work in the presence of a harsh environment。Meanwhile, solve the problem that the air gap of motor is bigger, dexterously motor rotary reciprocating motion is converted into the linear reciprocating motion of valve。Meanwhile, stator tooth slot structure simplifies the wire winding of motor, makes motor winding be evenly distributed, and stator Stator notching and skewed stator slot reduce the torque fluctuations during operation of motor。In motor, built-in Hall element can make motor control more accurate simultaneously。

Detailed description of the invention
Refer to shown in accompanying drawing 1, this utility model is in cylindrical casing 1, one cylindrical sleeve 2 is set, between casing 1 and sleeve 2, being cylindrical stator assembly, be cylindrical rotor assembly at sleeve 2 center, cylindrical casing 1 one end is spacing end cap 9, encapsulation process is done, it is prevented that enter the liquid in sleeve 2 along rotating shaft and enter stator module between sleeve 2 and spacing end cap 9；The upper and lower symmetry of rotor core 6 in described rotor assembly has platform, upper and lower platform is pasted magnet steel 5 respectively, and magnet steel 5 polarity on upper and lower platform is identical, and length is different。Rotor magnetic steel has four (two pairs), wherein has two (a pair) magnet steel (N pole, S pole) slightly short。
The roller end at described rotor core 6 center, is fixed with a steel ball 7, rotating shaft other end limited location pin 8 in off center position。
Having groove 10 between the tooth 12 of the stator core 4 in described stator module, around stator winding 3 in groove 10, have little groove 11 in crown 12 end, in the end of winding 3 equipped with sensor cluster, stator winding arrangement constitutes the winding method of a positive and a negative。
Stator core is made up of silicon steel sheet closed assembly, and have rotated certain angle during silicon steel sheet closed assembly。
Rotor core is made by monoblock soft magnetic materials or by silicon steel sheet closed assembly。
The roller end steel ball of rotor assembly, for putting into after in the groove of valve, can be converted into the linear reciprocating motion of valve by the crankmotion of motor。
Further illustrate operation principle of the present utility model with reference to the accompanying drawings: produce air-gap field by the magnet steel of motor rotor component, regulate the sense of current flowed in stator winding, the Impact direction making motor winding changes, motor applies the deflection angle amplitude that deflection angle is motor during rated current, output torque under certain deflection angle is relevant with the size of current of applying, and the output torque of motor is also relevant with the axial dimension size of motor rotor core。It is less that the air gap of motor can design, and this is difficult to realization in existing moving-coil type and moving-magnetic type limited angle torque motor。
