Two normally open contacts 28 are fixed on the inner top of the protection box 1, a capacitor 29, a diode 30 and an electromagnet 31 are fixed on the inner wall of the protection box 1, the inner wall of the protection box 1 is connected with an opening and closing block 33 through an opening and closing spring 32, two opening and closing contacts 27 abutting against the opening and closing block 33 are fixed on the inner wall of the protection box 1, the two opening and closing contacts 27 are connected by the opening and closing block 33, the normal connection of a motor circuit is ensured, once the two opening and closing contacts 27 are disconnected, a power supply circuit of the motor is interrupted, the motor does not work any more, and therefore heat is not generated any more, thereby protecting the motor circuit from being damaged, the ejector rod 16 made of piezoelectric ceramics can be used for driving the motor circuit to rotate, the capacitor 29 is powered, the diode 30 prevents electric power from leaking, and the normally closed contact 9 and the normally open contact 28 form two control switches to control the connection state of the capacitor 29, the electromagnet 31 and the ejector rod 16;
when the motor current circuit is over-current, the electrorheological fluid in the over-current groove 23 can receive the impact of large current, so that the original liquid electrorheological fluid is solidified, the process is accompanied with obvious expansion, the expansion can cause the over-current push block 25 to be pushed to move, and further the over-current push rod 26 pushes the electric plate 7 to move, because the over-current state causes the sudden change of the electrorheological fluid form, the electric plate 7 directly abuts against the two normally open contacts 28, because the temperature of the motor does not rise instantly at the over-current moment, the temperature push block 4 can not move obviously, so that a great gap can be generated between the electric plate 7 and the temperature push rod 5, the two normally closed contacts 9 are disconnected, the position of the electric plate 7 is changed greatly, the fan 11 is directly adjusted to the maximum output high heat power, and the generation of the following over-current process can be better responded, therefore, the motor can be timely cooled, serious thermal damage caused by overcurrent is avoided, and the safety of internal circuits of the motor is protected;
the separation of the two normally closed contacts 9 is triggered at the moment of overcurrent, so that the two normally open contacts 28 are switched on, the power connection circuit of the ejector rod 16 and the capacitor 29 is effectively switched on, the circuit of the capacitor 29 and the electromagnet 31 is interrupted, and the ejector rod 16 is made of piezoelectric ceramics, so that the ejector rod 16 can continuously generate current when being continuously impacted by the bump 19, further, the capacitor 29 is effectively charged in the state, the fan 11 in the state reaches the maximum output power, and the most efficient charging can be realized;
along with the increase of the overcurrent time, if the fan 11 works to control the temperature of the motor in an overcurrent state, then the heat damage caused by the overcurrent does not exist, and the motor does not need to be adjusted, however, if the internal temperature of the motor finally and continuously rises, the mercury in the temperature sensing tank 2 continuously absorbs heat and expands, and finally the temperature push block 4 moves for a sufficient distance, so that the two normally closed contacts 9 are switched on again, at the moment that the two normally closed contacts 9 are switched on, because the capacitor 29 has obtained a sufficient charge amount at this time, a large voltage difference exists at the two ends, and the extrusion power supply of the piezoelectric ceramic is not continuously performed, so that the existence of the voltage difference enables the capacitor 29 to effectively discharge the electromagnet 31 until the voltage difference disappears;
at the moment when the capacitor 29 discharges to the electromagnet 31, the electromagnet 31 will be electrified and magnetized, and then attract the opening and closing block 33 to move, so that the opening and closing block 33 overcomes the elastic force of the opening and closing spring 32 to separate from the opening and closing contact 27, so that the power supply circuit of the motor is interrupted, so that the electrorheological fluid in the overcurrent slot 23 loses power supply and recovers liquid state, thereby the overcurrent push block 25 resets, the two normally open contacts 28 separate, and then the capacitor 29 continuously discharges to the electromagnet 31 until the electric energy stored in the capacitor 29 is completely released, in the process, the opening and closing block 33 is always separated from the opening and closing contact 27, the power supply circuit of the motor is always disconnected, the motor stops working, the fan 11 still keeps working, the rapid diffusion of heat in the motor is realized, the motor can recover good working state, and finally the capacitor 29 discharges, the opening and closing block 33 resets, the two contacts 27 are connected, the motor is powered again to work;
in the whole process, the motor appears overflowing the back, if the excessive flow is not big, do not produce the thermal damage, then the motor keeps operating condition, if overflow and lead to the heat excessively to gather, so the motor will cut off the power supply and stop work, and can keep effectual heat dissipation, can be after effectively dispelling the heat a period of time simultaneously, automatic recovery operating condition, can realize the self-protection of motor, also reduce human intervention's intensity simultaneously, make the motor can regulate and control at my regulation and control, effectual conversion between continuous work and self-protection, make the motor can high-efficient continuous work can not receive the overcurrent damage again.
