The utility model comprises permanent magnets (31, to 3n, 41, to 4n,) with a given size and arranged in two parallel rows between which a given distance is maintained; coreless rectangular loop windings (61 to 6n) running through a cooling means (5) and arranged into adjacent rotors (1). The cooling means comprises connecting fittings (8, 9) arranged at the both ends of a row of rectangular cooling pipes (71 to 7n) each of which is provided with a round angle, and one pair or a plurality of pairs of inlets (10) and outlets (11); one or a plurality of solid metal support bars (12) are provided between the inlets and outlets of the cooling means to achieve the functions of a fixed test element and a rib reinforcement. The heat generated by the loop winding is taken away by the flowing refrigerant provided in the cooling pipe; coreless linear motor provided with a cooling means is capable to cool the motor efficiently and improve the thrust force and efficiency.
Description
Affiliated technical field
The utility model relates to a kind of centreless linear electric motors, especially carries the centreless linear electric motors of refrigerating function.
Background technology
At present, the structure of known centreless linear electric motors is to be made of stator and mover.Stator generally by permanent magnet according to specific rearranging; Mover generally is made of according to specific arrangement coil groups, draws power supply terminal by mover, by provide electric current to produce thrust to mover so that mover with respect to stator along the orientation rectilinear motion.But, produce a large amount of heats and cause efficiency of motor to reduce, and burn motor itself because of heating easily because coil generates heat after feeding electric current.
Summary of the invention
For the defective of the heating problem that overcomes existing centreless linear electric motors, the heater of motor is directly cooled off, the heating of centreless linear electric motors is directly taken away, thereby reached efficient cooling.And then the thrust and the efficient of raising motor.
The technical scheme that its technical problem that solves the utility model adopts is: the heating of centreless linear electric motors derives from the coil after the energising.In coil groups, penetrate the cooling body that constitutes by battery, the parallel equidistant arrangement of each cooling water pipe, the cross section of cooling water pipe has been down the rectangle of fillet.And a solid metal support bar is arranged between the import and export of cooling body, can play the fixed test element and play the reinforcement effect.Take away the heat that coil sends by input flowing coolant in cooling water pipe, thereby reach the purpose of cooling off the centreless linear electric motors effectively and improving centreless linear motor pushing force and efficient.
The beneficial effects of the utility model are, can directly take away the heat that the thermal source of centreless linear electric motors produces, and cool off the centreless linear electric motors effectively and improve centreless linear motor pushing force and efficient.The cooling body structure is simple and clear, and is easily manufactured.

Embodiment
In the motor-driven specific embodiment, centreless linear electric motors power supply terminal (13) is linked into outside servo-driver or frequency converter, accept the electric current that it sends, according to Fleming's left-hand rule, coil groups (61 in the centreless linear motor rotor (1), ..., 6n) just produce axial thrust with respect to centreless linear motor rotor (2), make centreless linear motor rotor (1) with respect to centreless linear motor stator electric (2) along permanent magnet (31, ..., 3n, 41 ... 4n) orientation, be axial linear movement.And, can be 3 cross streams electric currents to the electric current of centreless linear electric motors power supply terminal (13) input, also can be the single-phase linear electric current.
In the specific embodiment of motor cooling, after the outside next electric current of feeding entered in the centreless linear motor rotor (1), by flowing into cooling agent to cooling import (10), cooling agent was taken away the heat that coil is sent out, and flows out from coolant outlet (11).Cooling agent can be gas or liquid form.By cooling off direct heater, can reach cooling effect efficiently.
Claims (3)
1, a kind of centreless linear electric motors that carry cooling body, the stator of forming by permanent magnet arrangement and constitute by the mover that coil is formed, it is characterized in that: be installed with the cooling body that constitutes by battery in the coil of mover, each cooling water pipe parallel equidistant is arranged, the cross section of cooling water pipe has been down the rectangle of fillet, and a solid metal support bar is arranged between the import and export of cooling body.
2. the centreless linear electric motors that carry cooling body according to claim 1 is characterized in that: between the coreless coil of composition mover is adjacent arrangement, and it is shaped as rectangle.
