Abstract
The utility model relates to a direct current servomotor, which comprises a stator, a rotor iron core, a motor rotation shaft, a servomotor winding commutator, a servomotor winding, a velocity measuring motor winding and a velocity measuring motor commutator, wherein the rotor iron core is composed of silicon steel punching sheets which are overlapped and fixed on the motor rotation shaft, the direct current servomotor is characterized in that the rotor iron core is an iron core which is shared by the servomotor and a velocity measuring motor, the velocity measuring motor winding is arranged on the lower layer of an iron core tooth slot, a coil lead wire of the velocity measuring motor winding is connected with the velocity measuring motor commutator which is sleeved on one end of the motor rotation shaft, the servomotor winding is arranged on the upper layer of the iron core tooth slot, the coil lead wire of the servomotor winding is connected with the servomotor winding commutator which is sleeved on the other end of a motor shaft, since a design scheme that the servomotor motor and the velocity measuring motor share the iron core together is adopted, the length-diameter ratio and the volume of the motor can be manufactured to be very small, and the direct current servomotor accords with demands of miniaturization and integration developing direction.
Description
Technical field
The utility model relates to a kind of motor, relates in particular to the integrated DC servo motor of a kind of tachogenerator and DC servo motor, belongs to the mechanical ﹠ electrical technology field.
Background technology
Servomotor is a kind of important accurate electromechanical component in the automatic control system, it also is business automation equipment, indispensable drive disk assembly in various vehicles and the household electrical appliance, along with development of science and technology, servomotor is to high-performance, compactization, permanent magnetismization, non-brushing, the integrated direction development, at present, the speed-measuring method of servomotor generally all is to constitute the servomotor motor unit at the outside tachogenerator that independently is equipped with of servomotor, as: the patent No. is that 200620100281.9 patent names are: a kind of efficient direct current servomotor, a kind of like this structure is disclosed, it includes servomotor, tachogenerator, the roller end of servomotor is connected with the rotating shaft of speed measuring motor, the rotating shaft of servomotor connects the drive speed measuring motor by axle and rotates, although this design has realized the compact design of two kinds of motors, but, the draw ratio of motor, volume is still very big, makes the application scenario be restricted, and does not also meet miniaturization, the requirement of integrated development direction.
Summary of the invention
The purpose of this utility model provides a kind of volume little, integrated small-sized servomotor at the defective of above-mentioned existence.
The technical solution of the utility model is: a kind of DC servo motor, it comprises stator, rotor core, machine shaft, servomotor winding commutator, the servomotor winding, the speed measuring motor winding, the speed measuring motor commutator, described rotor core is servomotor and the shared iron core of speed measuring motor, described rotor core is laminated to be fixed on the machine shaft by the silicon steel punching and constitutes, commutator is socketed in the two ends of machine shaft respectively, the speed measuring motor winding is around the home in the lower floor of rotor core teeth groove and allow coil lead be connected with the speed measuring motor commutator, and the servomotor winding is around the home on the upper strata of rotor core teeth groove and allow coil lead be connected with servomotor winding commutator.
The beneficial effects of the utility model are: owing to adopted servomotor and this integrated design of the shared iron core of speed measuring motor, it is very little that the draw ratio of motor, volume can be done, thereby enlarged the motor application scope, met the requirement of miniaturization, integrated development direction.
