Description
Technical field
The present invention relates to a kind of single-phase motor, the single-phase motor is equipped with temperature protective device.
Background technology
For protection single-phase motor, it is necessary to carry out overcurrent protection to single-phase motor.The method of conventional overcurrent protection is,
The winding current of single-phase motor is detected, the working power of single-phase motor is cut off when winding current is excessive.Such a method
Weak point is that overcurrent protective device volume is larger, it is difficult to which it is machine integrated with single-phase electric.Motor breaks down in fact
When, temperature anomaly typically can be all shown, by detection temperature, single-phase motor can also be protected, using temperature protection
Mode, can simplify the structure of protector, volume-diminished is easy to machine integrated with single-phase electric.No. ZL2016606454144
Patent, is disclosed and temperature protective device is also provided with a kind of motor with overcurrent protective device, its casing, but its temperature is protected
The line construction of protection unit is more complicated, and the control element that its output end need to be led to outside casing, by casing outside control
Element could cut off motor power, in-convenience in use.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of single-phase motor with temperature protective device, temperature protection
Device is arranged on single-phase motor, and single-phase electric electromechanical source is directly cut off when temperature is too high in casing, is user-friendly.
The technical scheme is that, a kind of single-phase motor with temperature protective device, it include casing 1, stator 2,
The terminal box 5 of single-phase motor, temperature protector 10, stator is arranged on casing inner wall, and terminal box is arranged on the outer wall of casing
On；The bottom of terminal box is provided with the terminal plate 52 of single-phase motor, it is characterized in that, the top of terminal box is provided with overcurrent protection
The printed circuit board 11 of device, is provided with temperature sensor SJ in casing, and temperature sensor SJ pin is connected to temperature protector
Signal input part, the output end of temperature protector is serially connected in the current supply circuit of single-phase motor, when temperature is too high in casing
When cut off single-phase electric electromechanical source.
It is a feature of the present invention that temperature protector is arranged in the terminal box of single-phase motor, removes user from and voluntarily install
The inconvenience of protector, when temperature is too high, temperature protector directly cuts off single-phase electric electromechanical source, and protection is reliable.

The zero line of power supply.
The circuit structure of temperature protector is simple, and used electronic component is only several, welds the circuit of electronic component
Printed panel can be placed in single-phase motor terminal box.
The operation principle of temperature protector is, when the running temperature of single-phase motor is in tolerance band, temperature sensor
In two electrodes disconnect, trigger voltage can be formed between the control pole K and negative electrode T2 of controllable silicon SCR, controllable silicon SCR is in and led
Logical state；When the running temperature of single-phase motor exceeds tolerance band, mercury can be expanded to be connected with two electrodes, controllable silicon SCR
Control pole K and negative electrode T2 between formed short circuit, can not form trigger voltage between the control pole K and negative electrode T2 of controllable silicon SCR,
Silicon SCR cut-offs are controlled, the power supply of single-phase motor is cut off；When temperature drop to tolerance band single-phase motor can resume operation.
