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 for rolling screen door lifting.
Background technology
Tube shaped electric machine is mainly used in the lifting of rolling screen door, therefore, requires tube shaped electric machine can shut down rapidly to guarantee the lifting position of rolling screen door when tube shaped electric machine power-off, 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 same one 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, assembling difficulty, has also reduced the reliability of braking simultaneously.
Summary of the invention
The invention solves this end structure that the existing motor of prior art arranges brake assemblies and magnetizing coil too complicated, 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 by the following technical programs: it comprises casing, in casing, be equipped with stator, in stator, be provided with rotor, the armature spindle two ends of rotor and casing form rotary support and can in casing, move axially, one end of casing inside is provided with magnetizing coil, this magnetizing coil is synchronizeed switching electricity with motor, one end that armature spindle and magnetizing coil are adjacent is fixed with suction iron component, and armature spindle is arranged with Compress Spring corresponding to the position of inhaling between iron component and rotor core; The inner other end of casing is fixed with quiet brake disc, and the other end relative with inhaling iron component on armature spindle is fixed with the moving brake disc corresponding with quiet brake disc; When magnetizing coil and motor are switched in the lump, the magnetic force that magnetizing coil produces by inhale iron component adhesive make resistance that rotor overcomes Compress Spring in casing to this side shifting of magnetizing coil, moving brake disc and the disengagement of quiet brake disc, electricity
Machine runs well; When magnetizing coil and motor in the lump power-off, the magnetic force of magnetizing coil disappears, and at the effect lower rotor part of Compress Spring, in casing, to one end that quiet brake disc is set, moves, and moving brake disc and quiet brake disc mutually compress and stop rotor to rotate, and motor shuts down rapidly.The two ends that the present invention is arranged in casing by magnetizing coil, suction iron component and quiet brake disc, moving brake disc are inner, overcome the too complicated problem of motor one end structure, thereby are convenient to the assembling of motor, also improved the reliability of brake.When motor and magnetizing coil are switched in the lump, magnetizing coil obtains electric generation magnetic field, and inhales iron component generation magneticaction adhesive, thereby the axial magnetizing coil of rotor driven one end moves axially, moving brake disc and the disengagement of quiet brake disc, and motor is normally transported
Turn; When magnetizing coil and motor in the lump power-off, the magnetic force of magnetizing coil disappears, and at the effect lower rotor part of Compress Spring, in casing, to one end that quiet brake disc is set, moves, and moving brake disc and quiet brake disc mutually compress and stop rotor to rotate, and motor shuts down rapidly.
As preferably, the external diameter of described 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 reliable feature of braking.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention.
Embodiment
Below by specific embodiment, and by reference to the accompanying drawings, technical scheme of the present invention is described in further detail.
Embodiment: as shown in Fig. 1, in casing 1, be equipped with stator 2, in stator 2, be provided with rotor 3, armature spindle 4 two ends of rotor 3 and casing 1 form rotary support and can in casing, move axially, one end of casing inside is provided with magnetizing coil 5, this magnetizing coil 5 is synchronizeed switching electricity with motor, one end that armature spindle 4 is adjacent with magnetizing coil 5 is fixed with inhales iron component 6, and armature spindle 4 is arranged with Compress Spring 8 corresponding to the position between suction iron component 6 and rotor core 7; The inner other end of casing is fixed with quiet brake disc 9, and the other end relative with inhaling iron component 6 on armature spindle is fixed with the moving brake disc 10 corresponding with quiet brake disc 9, and the moving external diameter of brake disc 10 and the external diameter of quiet brake disc 9 all match 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 by inhale iron component 6 adhesives make resistance that rotor overcomes Compress Spring in casing to this side shifting of magnetizing coil, moving brake disc is thrown off with quiet brake disc, motor normal operation; When magnetizing coil and motor in the lump power-off, the magnetic force of magnetizing coil disappears, and at the effect lower rotor part of Compress Spring, in casing, to one end that quiet brake disc is set, moves, and moving brake disc and quiet brake disc mutually compress and stop rotor to rotate, and motor shuts down rapidly.
