Detailed Description
The technical solution of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
A first embodiment of the motor of the present invention is shown in fig. 1, and includes a power supply circuit 10, a temperature measuring element 20 and a plurality of windings 30; the power supply circuit 10 is electrically connected with the plurality of windings 30, and the power supply circuit 10 is used for supplying power to the windings 30; the temperature measuring element 20 is electrically connected with the power supply circuit 10, and the temperature measuring element 20 is abutted with the winding 30; when the temperature measuring element 20 detects that the temperature of the winding 30 exceeds a preset value, the power supply circuit 10 cuts off the power supply to the winding 30.
In this embodiment, there are three windings 30, three windings 30 are electrically connected to each other, and the power supply circuit 10 is electrically connected to one of the windings 30, so that when the motor obtains power input, the power supply circuit 10 can simultaneously supply power to the three windings 30, thereby ensuring the normal operation of the motor.
At this moment, the temperature measuring element 20 is one, the temperature measuring element 20 is abutted against the outer surface of one winding 30, the preset temperature value for cutting off power supply is limited to 110 ℃, and the preset temperature value for recovering power supply is 80 ℃, so when the motor is in an abnormal working state, the winding 30 generates high temperature, the temperature measuring element 20 can timely detect the temperature of the winding 30, the power supply circuit 10 can timely cut off the power supply to the winding 30 when the temperature of the winding 30 exceeds 110 ℃, and the motor is prevented from being damaged due to the working in a high-temperature state; similarly, if the temperature of the motor is increased to exceed the preset value only due to long-time operation, the temperature of the winding 30 is automatically decreased only after the motor stops operating for a period of time, that is, after the temperature of the winding 30 is lower than 80 ℃, the power supply circuit 10 can supply power to the winding 30 again, so that the motor continues to operate normally.
Of course, the number of the windings 30 and the temperature measuring elements 20 is not limited, and the matching mode of the windings 30 and the temperature measuring elements 20 is not unique; for example, one temperature measuring element 20 may be used to detect the temperature of one of the windings 30, and a matched number of temperature measuring elements 20 may be provided, so that each winding 30 has a temperature measuring element 20 for detection, and the specific arrangement mode is selected by a technician according to the requirement.
In addition, the temperature measuring element 20 may be directly abutted against the outer surface of the winding 30, or a heat transfer member may be provided between the temperature measuring element 20 and the winding 30 to realize indirect heat transfer between the temperature measuring element 20 and the winding 30, that is, the specific installation manner may be selected by those skilled in the art according to the needs.
The second embodiment of the motor of the present invention is shown in fig. 2, and is substantially the same as the first embodiment of the motor, except that the temperature measuring element is a temperature switch 21, the temperature switch 21 is connected in series on the path of the power supply circuit 10 and the winding 30, and when the temperature of the winding 30 measured by the temperature switch 21 exceeds the preset value, the temperature switch 21 is turned off.
For example, the temperature switch 21 may be a normally closed switch, the temperature switch 21 is only abutted against one of the windings 30, and since the operating states of the windings 30 are substantially the same, the temperature switch 21 can meet the basic requirement only by detecting one winding 30.
When the temperature of the winding 30 is not higher than the preset value, the temperature switch 21 will keep the closed state, so the power supply circuit 10 can keep supplying power to the winding 30; when the temperature of the winding 30 is higher than the preset value, the temperature switch 21 will be automatically turned off, so as to cut off the electrical connection path between the power supply circuit 10 and the winding 30, and prevent the motor from continuing to operate in an abnormal state.
It should be noted that the temperature switch 21 may be a normally closed type or a normally open type, and whatever type of temperature switch 21 is selected, the temperature switch 21 is ensured to be able to cut off the electrical connection between the power supply circuit 10 and the winding 30 when the motor is abnormal.
Of course, the temperature switches 21 may be provided in plural, taking fig. 3 as an example, at this time, three temperature switches 21 are adopted, the three temperature switches 21 are respectively abutted to the three windings 30, and since the three temperature switches 21 are connected in series at this time, as long as the temperature of the winding 30 measured by any one temperature switch 21 exceeds the preset value, the disconnection of the temperature switch 21 can cut off the power supply of the power supply circuit 10 to the windings 30, thereby providing an important guarantee for the normal operation of the motor.
The third embodiment of the motor of the present invention is shown in fig. 4, and is substantially the same as the second embodiment of the motor, except that the motor further includes an insulating strip 40, the insulating strip surrounds the plurality of windings 30, the insulating strip 40 abuts against the plurality of windings 30, and the insulating strip 40 also abuts against the temperature switch 21.
For example, in this embodiment, the temperature switch 21 abuts against the uppermost winding 30, if the uppermost winding 30 does not generate heat due to a special fault of the motor, but both of the lower windings 30 are in a high-temperature state, since the insulating strip 40 can transfer the heat of the lower windings 30 to the temperature switch 21, the power supply circuit 10 can still cut off the power supply to the windings 30, that is, this embodiment can protect the motor against various conditions.
It should be noted that, when the insulating strip 40 is provided, it should preferably be made of a material with better heat conductivity, so that heat can be better transferred to the temperature switch 21, thereby ensuring that the temperature switch 21 can timely turn off the power supply of the power supply circuit 10 to the winding 30 when the motor fails.
A fourth embodiment of the motor according to the present invention is shown in fig. 5, which is substantially identical to the first embodiment of the motor except that the temperature measuring element is a temperature sensor 22, and the temperature sensor 22 is used for detecting the temperature of the winding 30.
Utilize temperature sensor 22 to carry out the butt with one of them winding 30, when carrying out work, temperature sensor 22 can monitor the real-time temperature of winding 30 constantly to send monitoring result to supply circuit 10, if temperature sensor 22 surveyed the temperature of winding 30 and is higher than the default, supply circuit 10 just can cut off the power supply to winding 30, thereby avoids the motor to carry out work under overheated state.
Of course, the temperature sensors 22 may also be provided in plurality, taking fig. 6 as an example, at this time, three temperature sensors 22 are adopted, the three temperature sensors 22 are respectively abutted to the three windings 30, and since the three temperature sensors 22 are all independently connected to the power supply circuit at this time, as long as the temperature of the winding 30 measured by any one temperature sensor 22 exceeds the preset value, the power supply circuit 10 will cut off the power supply to the winding 30, thereby providing an important guarantee for the normal operation of the motor.
The fifth embodiment of the motor of the present invention is shown in fig. 7, which is substantially the same as the fourth embodiment of the motor, except that the motor further includes an insulating strip 40, the insulating strip surrounds the plurality of windings 30, the insulating strip 40 abuts against the plurality of windings 30, and the insulating strip 40 also abuts against the temperature sensor 22.
For example, in this embodiment, the temperature sensor 22 abuts against the uppermost winding 30, if the uppermost winding 30 does not generate heat due to a special fault of the motor, but both of the lower windings 30 are in a high-temperature state, since the insulating strip 40 can transfer the heat of the lower windings 30 to the temperature sensor 22, the power supply circuit 10 can still cut off the power supply to the windings 30, that is, this embodiment can protect the motor against various conditions.
It should be noted that, when the insulating strip 40 is provided, it should preferably be made of a material with better heat conductivity, so that heat can be better transferred to the temperature sensor 22, thereby ensuring that the power supply circuit 10 can timely cut off the power supply to the winding 30 when the motor fails.
The utility model also provides an oil press, including foretell motor to make the oil press more comprehensive to the protection of motor, improved the life of oil press promptly greatly.
The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
