The rotor iron core is positioned on a same axial line with the stator iron core. Wherein, the rotor iron core is configured with circular structure; the surface for the internal circle of the rotor iron core is configured with heteromorphy circumference surface; the stator iron core is positioned inside the internal circle of the rotor iron core; the stator winding is positioned on the external circumference surface of the stator iron core. The utility model enables convenient installation and high reliability; because the stator winding is positioned on the external circumference surface of the stator iron core, no special tools needs for winding, thus greatly simplifying the processing techniques and boosting the production efficiency.
Description
Technical field
The utility model relates to a kind of transformer, is specifically related to be used for the resolver of servomotor.
Background technology
Existing resolver has and structure like the motor type, as shown in Figure 1, stator core 12, stator winding 13, rotor core 11 are arranged, wherein stator core is a loop configuration, rotor core 11 is located in the interior ring of stator core 12, stator winding 13 is located at the inner peripheral surface of stator core 12, corresponding with the outer peripheral face of rotor core 11, the outer peripheral face of rotor core 11 is generally oval side face or has equally distributed quincunx side face, so that the inner peripheral surface of the outer peripheral face of rotor core 11 and stator core 12 forms variable gap.When rotor core 11 in stator core 12 inner stressed rotations, the amplitude of stator winding 13 output AC voltages is dextrorotation with rotor angular displacement or surplus rule of revolving changes, and obtains the angle position signal after the conciliation.But when the resolver of this structure plays SERVO CONTROL on being installed to some motor, as shown in Figure 2, the stator support 3 of motor 2 is fixedly connected with the stator core 12 of the stator core 22 of motor 2 and resolver 1 as fixed support, stator support 3 need be designed to the T shape structure with bending, because the restriction of locus, install extremely inconvenient, need special spooling equipment around the home when the stator winding 13 of resolver 1 is produced in batches in addition, increase difficulty of processing, also brought the difficulty of maintenance simultaneously.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above that prior art exists, and provides a kind of and can be applicable to multiple occasion, installs and adjust the resolver that is used for servomotor extremely easily.
The purpose of this utility model is achieved by following technical scheme: a kind of resolver that is used for servomotor, comprise rotor core, stator core and be arranged on stator winding on the stator core, rotor core and stator core are coaxially set, wherein, described rotor core is a loop configuration; The inner ring surface of ring is special-shaped side face in the described rotor core; Described stator core is located in the interior ring of rotor core; Described stator winding is located on the outer peripheral face of stator core.
The above-mentioned resolver that is used for servomotor, wherein, the inner ring surface of described rotor core is oval side face or has the quincunx side face that is evenly distributed, so that the outer peripheral face of the inner face of rotor core and stator core forms variable gap.
The above-mentioned resolver that is used for servomotor, wherein, the outer peripheral face of described stator is provided with uniform a plurality of slot for windings, and described stator winding is wrapped on the tooth boots between each adjacent slot for winding.
Owing to adopted the technical solution of the utility model, be about to rotor core and be made as loop configuration, stator core is located in the interior ring of rotor core, when making the resolver of this structure be used for some servomotor, relative prior art, it is extremely convenient to install, the reliability height; Because stator winding is located on the outer peripheral face of stator core, and coiling does not need special installation yet, makes simplified processing technology, production efficiency improves again.
