Description
Technical field
The utility model relates to technical field of motors, especially a kind of intelligent overtemperature protection stepping motor.
Background technology
Increasingly mature and perfect along with technology, stepping motor obtains fast development, and step motor control performance is good, it can realize opened loop control, namely the number of pulses inputted by driver signal input and frequency, realize angle and the speeds control of stepping motor, without the need to feedback signal.And the heating of stepping motor is very serious; situation as excessive in some stalls, long-time load; the temperature of stepping motor can raise rapidly; motor can be damaged time serious; stepping motor on some automatic production lines because work long hours also can go out overheated and cause the damage of motor; bring loss to enterprise, can not automatically recover after some traditional overtemperature protection motors are stopped, and inconvenient.
Utility model content
The technical problems to be solved in the utility model is: in order to solve stepping motor temperature too high time can burn out motor and temperature reduce after can not automatically recover running, a kind of intelligent overtemperature protection stepping motor is now provided.
The utility model solves the technical scheme that its technical problem adopts: a kind of intelligent overtemperature protection stepping motor, comprise housing, first wire and the second wire, body is provided with in described housing, also comprise magnet, spring and magnetic material, described housing is provided with fixed head, described spring one end is fixedly connected with fixed head, the other end is fixedly connected with described magnetic material, described magnetic material and housing are slidably connected, described magnet to be fixed on housing and to be positioned at the opposite of magnetic material, the one side that described magnetic material is relative with magnet is provided with the first sheet metal, described magnet is provided with the second sheet metal matched with described first sheet metal, one end of described first wire is connected with the first sheet metal, the other end is connected with body, described second sheet metal is connected with the second wire, the temperature of body passes to housing, housing passes to magnetic material, when the temperature of motor exceedes the Curie point of magnetic material (for all magnetic materials, be not all there is magnetic at any temperature, this critical temperature is called for short Curie point, the Curie point of often kind of magnetic material is all different, when temperature is greater than the Curie point of magnetic material, magnetic material just loses magnetism) time, magnetic material loses magnetism, magnetic material is separated with magnet under the action of the spring, realize motor power-off, when the Curie point of temperature lower than magnetic material, the connection recovering again the first thin slice and the second thin slice under the effect of magnet realizes being energized.
In order to personal security, prevent from touching sheet metal, further, also comprise protective cover, described protective cover is installed in the top described housing being positioned at described fixed head and magnet.
The beneficial effects of the utility model are: intelligent overtemperature protection stepping motor of the present utility model is by installing magnetic material and magnet; realize the motor auto-breaking when the Curie point of temperature higher than magnetic material; when the Curie point of temperature lower than magnetic material, motor recovers again normal operation; the utility model structure is simple; optimize the serviceability of motor; successful, has carried out good intelligent overtemperature protection to motor.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is schematic diagram of the present utility model;
In figure: 1, body, 2, housing, the 3, second wire, the 4, second sheet metal, 5, magnet, the 6, first sheet metal, 7, magnetic material, 8, spring, 9, protective cover, 10, fixed head, the 11, first wire.
Embodiment

Embodiment 1
A kind of intelligent overtemperature protection stepping motor as shown in Figure 1, comprise housing 2, first wire 11 and the second wire 3, body 1 is provided with in housing 2, also comprise magnet 5, spring 8 and magnetic material 7, housing 2 is provided with fixed head 10, spring 8 one end is fixedly connected with fixed head 10, the other end is fixedly connected with described magnetic material 7, described magnetic material 7 is slidably connected with housing 2, magnet 5 to be fixed on housing 2 and to be positioned at the opposite of magnetic material 7, the one side that magnetic material 7 is relative with magnet 5 is provided with the first sheet metal 6, magnet 5 is provided with the second sheet metal 4 matched with the first sheet metal 6, one end of first wire 11 is connected with the first sheet metal 6, the other end is connected with body 1, second sheet metal 4 is connected with the second wire 3, second wire 3 connects dispatch from foreign news agency.
Stepping motor above-mentioned as shown in Figure 1 also comprises protective cover 9, and described protective cover 9 is installed in top housing 2 being positioned at fixed head 10 and magnet 5.
Operation principle
The magnetic material 7 that the thermal creep stress that can bear according to stepping motor is suitable, magnetic material 7 can slide on the housing 2 of motor, magnetic material 7 is held by magnet 5, spring 8 between magnetic material 7 and fixed head 10 is in extended state, the temperature of body 1 passes to housing 2, the temperature of housing 2 passes to magnetic material 7, when the temperature of motor exceedes the Curie point of magnetic material 7: magnetic material 7 loses magnetism, magnetic material 7 will be separated with magnet 5 under the effect at spring 8 (i.e. the first sheet metal 6 and the second sheet metal 4 be separated), realizes motor power-off; When the Curie point of temperature lower than magnetic material 7: the connection recovering again the first sheet metal 6 and the second sheet metal 4 under the effect of magnet 5 realizes being energized.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to right.
