Description
Technical field
The utility model technical field of motors, specifically, particularly high frequency straight line electric rotating machine.
Background technology
Prior motor generally can only be done rectilinear motion separately, perhaps rotates separately.And linear electric motors could reflect the straight-line positional information of motor owing to self do not have feedback device so need to pass through peripheral feedback device, and its volume is big, the slow and hysteresis of response.Along with the high speed development of automatic control technology and microcomputer, the positioning accuracy of all kinds of automatic control systems is had higher requirement, in this case, traditional motor can not satisfy the requirement of modern control system.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of high frequency straight line electric rotating machine, not only can do rectilinear motion but also can rotate, and realizes fast, level and smooth, no inserted tooth, does not have hysteresis.
The technical solution of the utility model is as follows: a kind of high frequency straight line electric rotating machine, comprise casing and the jointing that is installed on the casing, linear drives parts and rotary driving part are installed in casing, described linear drives parts are made up of permanent magnet, framework and moving coil, at the middle mounting permanent magnet of framework, described moving coil is enclosed in around the permanent magnet; Described rotary driving part comprises rotating servo motor, connecting axle, shaft coupling and projecting shaft, middle part in casing is provided with a square box, described shaft coupling is positioned at square box, one end of described moving coil is connected with a side of square box, described rotating servo motor is fixed on the back of square box, its output shaft passes square box and is connected with connecting axle by shaft coupling, the other end of described connecting axle is connected with projecting shaft, the output shaft of described rotating servo motor, connecting axle, the axis of projecting shaft and shaft coupling is on same straight line, described projecting shaft passes casing, in casing, be provided with one with the guide rail of square box coupling, the median plane of described guide rail is parallel with projecting shaft, described square box is installed on the guide rail, afterbody at rotating servo motor is equipped with rotary encoder, be provided with linear encoder in casing, the read head of described linear encoder is installed on the casing, and the grating chi of described linear encoder is installed on the square box.
Adopt technique scheme, give electrical power, at motor internal, moving coil drives the whole moving linearly of described rotary driving part, and being projecting shaft in the motor external presentation is also rotating doing the straight-line while.Rectilinear motion: give coil electricity, in coil, produce electric current, and then on coil, produce and the proportional power of electric current, make coil motion vertically in air gap; The sense of current by coil determines its direction of motion; Thereby finish straight reciprocating motion, when moving linearly, linear encoder reads and writes down the linear position linearity of projecting shaft; Rotatablely move: driven by servomotor is finished and is rotatablely moved, the rotation angle information of the rotary encoder feedback servo motor on the servomotor, and characteristic and position feedback perfect adaptations such as realization is quick, level and smooth, no inserted tooth, nothing hysteresis response, volume is little.
In technique scheme, described framework is " mouth " font structure, and described permanent magnet is arranged in the framework and constitutes " day " font structure with framework.
Compared with prior art, advantage of the present utility model is: these high frequency straight line electric rotating machine collection linear drives parts and rotary driving part and feedback element are one, characteristics such as realization is quick, level and smooth, no inserted tooth, nothing hysteresis response, and combine with position feedback, the frequency height, volume is little, can select the motor of different strokes, different accuracy as required for use, realize high frequency, the needs of different application occasion are satisfied in high-precision motion.
