Abstract
The invention relates to a tubular motor, in particular to a tubular motor for lifting a roller shutter door. A rotary support is formed by both ends of a rotor shaft of a rotor and a shell, and the rotary support can move axially in the shell; an exciting coil is arranged at one end inside the shell; the exciting coil is switched on and off with the motor synchronously; an iron absorbing assembly is fixed at one end of the rotor shaft adjacent to the exciting coil; a compression spring is sleeved on the rotor shaft corresponding to a position between the iron absorbing assembly and a rotor core; a static brake disc is fixed at the other end inside shell; and a moveable brake disc corresponding to the static brake disc is fixed at the other end of the rotor shaft opposite to the iron absorbing assembly. When the exciting coil and the motor are switched on synchronously, the iron absorbing assembly is absorbed by a magnetic force generated by the exciting coil, so that the rotor overcomes the resistance of the compression spring to move toward the side of the exciting coil in the shell, the moveable brake disc is separated from the static brake disc and the motor operates normally. When the exciting coil and the motor are switched off synchronously, the magnetic force generated by the exciting coil disappears, the rotor moves toward the end where the static brake disc is arranged in the shell under the effect of the compression spring, the static brake disc and the moveable brake disc are compressed to each other to resist the rotor to rotate, and the motor stops rotating rapidly.
Description
Technical field
The present invention relates to a kind of tube shaped electric machine, particularly a kind of tube shaped electric machine that is used for the rolling screen door up-down.
Background technology
Tube shaped electric machine is mainly used in the up-down of rolling screen door, therefore, when tube shaped electric machine cuts off the power supply, requires tube shaped electric machine can shut down rapidly to guarantee the lifting position of rolling screen door, and this just needs tube shaped electric machine to possess good braking quality.Existing tube shaped electric machine all adopts the mode of direct travelling brake assembly to control brake; This has just caused brake assemblies and magnetizing coil must be arranged on the same end of tube shaped electric machine; And this end structure that has caused motor that brake assemblies and magnetizing coil be set is too complicated; The assembling difficulty has also reduced the reliability of braking simultaneously.
Summary of the invention
It is too complicated to the invention solves this end structure that the existing in prior technology motor is provided with brake assemblies and magnetizing coil, and the assembling difficulty has also reduced the integrity problem of brake simultaneously, provides a kind of easy to assembly, and reliable tube shaped electric machine brakes.
Above-mentioned technical purpose of the present invention solves through following technical scheme: it comprises casing; Be equipped with stator in the casing; Be provided with rotor in the stator; The armature spindle two ends of rotor and casing form rotation and support and can in casing, move axially, and an end of interior is provided with magnetizing coil, this magnetizing coil and motor synchronous switching; The end that armature spindle and magnetizing coil are adjacent is fixed with the suction iron component, and armature spindle is arranged with the compression spring corresponding to the position of inhaling between iron component and the rotor core; The interior other end is fixed with quiet brake disc, is fixed with the moving brake disc corresponding with quiet brake disc with the relative other end of suction iron component on the armature spindle; When magnetizing coil and motor are switched in the lump, the magnetic force that magnetizing coil produces will inhale the iron component adhesive make resistance that rotor overcomes the compression spring in casing to this side shifting of magnetizing coil, moving brake disc and the disengagement of quiet brake disc, motor normal operation; When magnetizing coil and motor cut off the power supply in the lump, the magnetic force of magnetizing coil disappeared, and moved to the end that quiet brake disc is set in casing at the effect lower rotor part of compression spring, and dynamic friction dish and static friction dish compress the prevention rotor rotation each other, and motor shuts down rapidly.The present invention is inner with the two ends that magnetizing coil, suction iron component and quiet brake disc, moving brake disc are arranged in casing, has overcome too complicated problems of motor one end structure, thereby has been convenient to the assembling of motor, has also improved the reliability of brake.When motor and magnetizing coil were switched in the lump, magnetizing coil got electric generation magnetic field, and inhaled iron component generation magneticaction and adhesive, moved axially thereby drive rotor axial magnetizing coil one end, and moving brake disc is thrown off with quiet brake disc, the motor normal operation; When magnetizing coil and motor cut off the power supply in the lump, the magnetic force of magnetizing coil disappeared, and moved to the end that quiet brake disc is set in casing at the effect lower rotor part of compression spring, and dynamic friction dish and static friction dish compress the prevention rotor rotation each other, and motor shuts down rapidly.
As preferably, the external diameter of said moving brake disc and the external diameter of quiet brake disc all match with the internal diameter of casing inner wall, thereby can strengthen moving brake disc and the diameter of quiet brake disc and both contacts area as far as possible, to increase both frictional force, strengthen braking effect.
Therefore, the present invention has easy to assembly, the brake reliable characteristics.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Embodiment
Pass through specific embodiment below, and combine accompanying drawing, do further bright specifically technical scheme of the present invention.
Embodiment: as shown in Figure 1; Be equipped with stator 2 in the casing 1, be provided with rotor 3 in the stator 2, armature spindle 4 two ends of rotor 3 and casing 1 form rotation and support and can in casing, move axially; One end of interior is provided with magnetizing coil 5; This magnetizing coil 5 and motor synchronous switching electricity, armature spindle 4 are fixed with magnetizing coil 5 adjacent ends inhales iron component 6, and armature spindle 4 is arranged with compression spring 8 corresponding to the position of inhaling between iron component 6 and the rotor core 7; The interior other end is fixed with quiet brake disc 9, is fixed with the moving brake disc 10 corresponding with quiet brake disc 9 with inhaling the iron component 6 relative other ends on the armature spindle, and the external diameter that moves external diameter and the quiet brake disc 9 of brake disc 10 all matches with the internal diameter of casing 1 inwall.
When magnetizing coil 5 and motor are switched in the lump, the magnetic force that magnetizing coil 5 produces will inhale iron component 6 adhesives make resistance that rotor overcomes the compression spring in casing to this side shifting of magnetizing coil, moving brake disc and the disengagement of quiet brake disc, motor normal operation; When magnetizing coil and motor cut off the power supply in the lump, the magnetic force of magnetizing coil disappeared, and moved to the end that quiet brake disc is set in casing at the effect lower rotor part of compression spring, and dynamic friction dish and static friction dish compress the prevention rotor rotation each other, and motor shuts down rapidly.
