Abstract
The utility model discloses a linear voice coil motor, comprising a stator and a rotor which rotates relatively to the stator; wherein the stator is composed of a soleplate, a coil and a coil retaining plate; a coil installation slot, in which the coil is housed, is arranged on the coil retaining plate; the soleplate, the coil and the coil retaining plate are installed together by means of vacuum injection through epoxy resin; the rotor is composed of a magnetic yoke and a magnet which is affixed to the magnetic yoke. Adopting above structure, the linear voice coil motor is capable of enabling the rotor to directly drive the loads to move linearly to-and-fro, thus realizing speedy and accurate localization of the loads.
Description
[technical field]
The utility model relates to a kind of motor, relates in particular to a kind of linear voice coil motor.
[technical background]
Along with development of modern industry, voice coil motor has obtained application more and more widely in line with its distinctive high response, high acceleration, high-speed, characteristics that volume is little.Yet rectilinear motion is traditionally normally realized by synchronous band, screw rod or ball-screw conversion indirectly by electric rotating machine, 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 or the like 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 technological trend in markets, field such as high-end automation equipment, Digit Control Machine Tool.
Therefore, the problem that how to provide a kind of linear voice coil motor to become current urgent need to solve.
[utility model content]
The technical problem that the utility model institute desire solves provides a kind of linear voice coil motor, and is poor by the caused rigidity of traditional ball-screw transmission to overcome, efficient is low, low-response and have shortcoming such as backlass.
The technical scheme that the utility model adopted is: a kind of linear voice coil motor, the mover that comprises stator, relative stator motion, wherein, described stator comprises base plate, coil and coil stationary plate, offer the coil mounting groove on the described coil stationary plate, described coil is contained in the described coil mounting groove, and described base plate, coil and coil stationary plate adopt the epoxide resin vacuum perfusion to be installed together; Described mover comprises yoke and magnet, and described magnet pasting is on described yoke.
Offer the cooling holes of passing through for cooling fluid on the described base plate.
But be provided with the temperature inductor that the perception coil temperature changes between the described coil.
The technique effect that the utility model reached is: the utility model linear voice coil motor can realize that by adopting said structure mover directly drives load and does reciprocating linear motion, and realizes the high speed and precision location of load.
