Abstract
The utility model discloses a linear motor, comprising a stator, and a mover which is moved relatively to the stator. The stator is composed of at least one magnet array module which comprises a magnet and a magnetic yoke, and the mover comprises an iron core and a coil. Rectangular teeth and rectangular grooves are formed in interval on the iron core, and the coil is inserted in the grooves. The iron core of the mover is fixed on a casing. The linear motor of the utility model can overcomes the shortcomings of weak rigidity, low efficiency, slow response, and reversal gaps which are caused by the driving of a traditional ball screw rod.
Description
[technical field]
The utility model relates to a kind of motor, refers to a kind of linear electric motors of winding coil relative stator motion especially.
[technical background]
Rectilinear motion is realized by synchronous band, screw rod or ball screw conversion indirectly by electric rotating machine traditionally, and the machine driving response is slow and hysteresis, there is certain tracking error, also influence the transmission stiffness of system, mechanically operated wearing and tearing and noise etc. all are the technical bottleneck of indirect drive in the high speed and precision automation equipment.The direct driving technologies that is made of linear electric motors has been cancelled the intermediate link between motor and the load, driving-chain between motor and the workbench is shortened to zero, having avoided shortcomings such as the backlass in the lead screw transmission, inertia, frictional force and rigidity deficiency, is the market and the technological trend in fields such as high-end automation equipment, Digit Control Machine Tool.High speed development along with automatic control technology and microcomputer, positioning accuracy to all kinds of automatic control systems is had higher requirement, in this case, conventional motors far can not satisfy the requirement of modern control system, for this reason, world many countries all studying, develop and using novel linear electric motors, makes that the application of linear electric motors is more and more wider in recent years.
[utility model content]
The technical problem that the utility model institute desire solves provides a kind of direct driving linear motor, to overcome by poor, the shortcomings such as efficient is low, low-response of the caused rigidity of traditional ball-screw transmission.
The technical scheme that the utility model adopted is: a kind of linear electric motors, comprise the mover that stator, relative stator are moved, and stator is made up of at least one magnet array module, and this array comprises magnet and yoke, and magnet is installed on the yoke at interval; Described mover comprises iron core and coil, forms rectangular teeth and rectangular channel at interval on the iron core, and described line chart embedding is in rectangular channel, and the iron core of described mover is fixed on above the casing.
Further improvement of the utility model is that described mover is made of iron core and coil priming by vacuum epoxy resin.
Further improvement of the utility model is that described iron core is laminated by silicon steel sheet and constitutes.
Further improvement of the utility model is that described casing links to each other with Connection Block, and this Connection Block is provided with attaching plug.
Further improvement of the utility model is that described mover can cool off with cooling fluid.
The technique effect that the utility model reached is: 1, mover directly drives load and does reciprocating linear motion, and has realized that the high speed of load is accurately located; 2,, thereby reduced the tracking error that lags behind and bring because of drive system owing to cancelled mechanical transmission mechanism such as leading screw, and the transmission stiffness height; 3, owing to avoided the mechanical friction and the energy loss of parts such as turn-screw, the motion noise is descended greatly and the efficient height; 4, maintainability is good, environmental suitability is strong.
