Abstract
The utility model discloses a noncore moving coil linear motor, comprising a stator and a mover in relative to the stator. The stator is at least composed of a magnetic array module, which comprises the upper and the lower magnetic yokes, with permanent magnets of different polar alternatively affixed to the upper and the lower magnetic yokes, thus forming air gap between the upper and lower magnetic yokes. The mover includes the framework and the coil, and can glide freely among the stator's air gap. Compared with the technologies of other linear motors, the utility model has no ripple thrust caused by the alveolus and no electromagnetic attraction between the mover and the stator, and therefore, the utility model has excellent static and dynamic characteristics.
Description
[technical field]
The utility model is about a kind of motor, refers to a kind of no-iron core moving-coil DC motor of winding 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, response is slow, transmission stiffness is low, and there is tracking error, also has wearing and tearing and noise etc. that its application in the high speed and precision automation equipment is restricted.The direct driving technologies that is made of linear electric motors makes the driving-chain between motor and the workbench shorten to zero, avoided shortcomings such as backlass in the lead screw transmission and rigidity deficiency, is the technological trend in fields such as automation equipment, Digit Control Machine Tool.
[utility model content]
The technical problem that the utility model institute desire solves provides a kind of no-iron core moving-coil DC motor of direct driving,, shortcomings such as efficient low, low-response and backlass poor by the caused rigidity of traditional ball-screw transmission to overcome.
The technical scheme that the utility model adopted is: a kind of no-iron core moving-coil DC motor, the mover that comprises stator, relative stator motion, stator is made up of at least one magnet array module, the magnet array module comprises upper and lower yoke, alternately paste the permanent magnet of opposed polarity on the upper and lower yoke, form air gap between upper and lower yoke, mover moves in air gap, mover comprises at least one coil groups, and coil groups comprises skeleton and the coil on the skeleton.
The skeleton of described mover is made of nonmagnetic substance, is interval with groove on it, and described coil is placed in the groove.
Described mover can be concentrated winding by modular a plurality of coil groups.
The coil groups of described mover is made of skeleton and coil priming by vacuum epoxy resin.
Described stator is the straight magnetic magnet array of modularization.
The distolateral non-magnetic field plate washer that is provided with of the permanent magnet that described stator is pasted on upper and lower yoke.
The technique effect that the utility model reached is: the utility model directly drives load and makes level and smooth linear reciprocating motion, realizes the high speed and precision location of load; The coil of the utility model mover places in the skeleton that nonmagnetic substance makes, and the electromagnetic attraction between ripple thrust that causes because of teeth groove and moving, stator not is quiet, dynamic characteristic is excellent.
