Abstract
The utility model relates to a tubular motor, and is especially relates to a tubular motor used for elevating a roller shutter door. two ends of a rotor shaft of a rotor and a casing form a rotary support, and enable axial movement in the casing, an exciting coil is provided at one end in the casing, the exciting coil and the motor enable synchronous energization and outage, a magnet component is fixed at one adjacent end of the rotor shaft and the exciting coil, a compression spring is sleeved at the position between the magnet component and a rotor iron core; a static brake disc is fixed at the other end in the casing, a movable brake disc corresponding to the static brake disc is fixed on the rotor shaft relative to the another end of the rotor shaft; when the exciting coil and the motor are energized, the magnetic force generated by the exciting coil enables pull-in on the magnet component, the movement of the resistance of the compression spring to the exciting coil in the casing can be overcome, the movable brake disc is disconnected to the static brake disc, the motor is in a normal operation; when the exciting coil and the motor enable power off, the magnetic force of the exciting coil is disappeared, the rotor moves towards to one end arranged with the static brake disc in the casing, a movable frication disc and a static friction disc are mutually compacted for preventing the rotation of the motor, and the operation of the motor can be rapidly stopped.
Description
Technical field
The utility model 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
The utility model has solved the existing in prior technology motor, and that this end structure of brake assemblies and magnetizing coil is set is too complicated, and the assembling difficulty has also reduced the integrity problem of brake simultaneously, provides a kind of easy to assembly, and brake reliable tube shaped electric machine.
The above-mentioned technical purpose of the utility model 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 utility model 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 utlity model has easy to assembly, the brake reliable characteristics.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Embodiment
Below by specific embodiment, and in conjunction with the accompanying drawings, do further bright specifically to the technical scheme of the utility model.
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.
