[0025] Moreover, the use of terms such as "first" and "second", etc., are used to distinguish one from another only and are not necessarily used to denote any such actual relationship or order between or among the elements.

[0026] A motor type voltage stabilizer, comprising a shell 1, a voltage regulating coil 2 arranged in the shell 1, a carbon brush assembly 3 slidingly contacting the surface of the voltage regulating coil 2, a transmission mechanism driving the reciprocating movement of the carbon brush assembly 3, a motor 4 in transmission connection with the transmission mechanism, and a control circuit module controlling the operation of the motor 4; the control circuit module comprises a voltage detection unit and a microprocessor 5, the voltage detection unit collects input and output voltage signals in real time and transmits them to the microprocessor 5, and the microprocessor 5 generates pulse signals to drive the motor 4 to reverse according to the voltage deviation value. The new motor type voltage stabilizer realizes the voltage regulating function by the matching transmission among the motor 4, the transmission structure and the carbon brush assembly 3. When connected to the external power supply, the motor 4 is driven to move, the transmission mechanism is driven to work by the motor 4, and the reciprocating movement of the carbon brush assembly 3 is driven by the transmission mechanism. Compared with the direct driving mode of the motor 4 driving the carbon brush assembly 3, the speed is better controlled, the axial positioning accuracy is improved, the mechanical idle stroke is reduced, the efficiency is improved, and the control circuit module is equipped. The control circuit module comprises a voltage detection unit and a microprocessor 5, which can monitor the voltage in real time and transmit the electrical signal to the microprocessor 5, and then generate pulse signals to drive the motor 4 to reciprocate according to the voltage deviation value. This control method is more accurate and reasonable and is more suitable for the motor type voltage stabilizer. Further, the transmission mechanism comprises a driving gear 6 fixedly connected with the output shaft of the motor 4, a driven gear 7 engaged with the driving gear 6, and a lead screw 8 coaxially connected with the driven gear 7, and a threaded sleeve 9 is arranged on the lead screw 8, and the carbon brush assembly 3 is in screw transmission connection with the lead screw 8 through the threaded sleeve 9. By adopting the above transmission structure scheme, the transmission mechanism comprises the driving gear 6, the driven gear 7 and the lead screw 8. The output shaft of the motor 4 drives the driving gear 6 fixedly connected with the output shaft to rotate, the driving gear 6 drives the driven gear 7 engaged with it to rotate, the driven gear 7 is coaxially connected with the lead screw 8, so as to drive the lead screw 8 to rotate, and the carbon brush assembly 3 can be in screw transmission connection with the lead screw 8 through the threaded sleeve 9, so that the motor 4 can drive the reciprocating movement of the carbon brush assembly 3. Compared with the traditional coaxial transmission, the transmission precision is higher, the axial offset value is not too large, the gear engagement transmission mode is not easy to slip and gap, the structure occupies small space, and the speed can be easily adjusted.

[0027] Further, the carbon brush assembly 3 comprises a left carbon brush and a right carbon brush symmetrically arranged, and the sliding track of the carbon brush assembly 3 covers the effective winding area of the voltage regulating coil 2. By adopting the above technical scheme, the carbon brush assembly 3 adopts a double-carbon brush design, two carbon brushes are connected through an elastic conductive medium and can keep synchronous sliding, which can reduce the contact resistance, and can still maintain normal conduction when one of the carbon brushes is damaged, has a longer service life compared with a conventional carbon brush, and the winding area of the voltage regulating coil 2 is in the sliding area of the carbon brush assembly 3, which means that the winding range of the voltage regulating coil 2 only needs to meet the demand in the voltage regulating range, so whether to increase or decrease the winding area can be selected according to the actual design condition, and cost can be saved.

[0028] Further, the lead screw 8 is provided with photoelectric limit sensors 10 at both ends, and the side wall of the threaded sleeve 9 is fixed with a trigger piece. When the trigger piece shields any photoelectric limit sensor 10, the microprocessor 5 cuts off the power supply of the motor 4. By adopting the above technical scheme, the photoelectric limit sensor 10 is arranged to transmit a signal to the microprocessor 5 when it is shielded, and the power supply of the motor 4 is cut off. The side wall of the threaded sleeve 9 is provided with a trigger piece, the photoelectric limit sensor 10 is located at both ends of the lead screw 8, and the threaded sleeve 9 is arranged at the center of the lead screw 8. When the threaded sleeve 9 axially moves too much, the trigger piece on the side wall of the threaded sleeve 9 will trigger the photoelectric limit sensor, thereby cutting off the power supply of the motor 4 and issuing an alarm, avoiding equipment failure caused by the offset of the carbon brush assembly 3, and playing a safety protection role. The light sensor adopts a light signal transmission mode for control, has fast transmission and rapid feedback, and is more reliable to use.

[0029] Further, the control circuit module further comprises an overvoltage protection unit. When the output voltage exceeds the set threshold value, the overvoltage protection unit triggers a relay to cut off the output loop of the voltage regulating coil 2. The overvoltage protection unit monitors the output voltage. When the output voltage exceeds the set threshold value, the information is transmitted to the relay, and the relay cuts off the output loop of the voltage regulating coil 2, thereby playing an overvoltage protection role. The stabilizer is often connected with a high-frequency electrical appliance, and the circuit inside is also relatively complex. Therefore, it is important for the stabilizer to have a protection module.

[0030] Further, the microprocessor 5 is built-in with a PID algorithm module, and the output pulse width and the voltage deviation value have a non-linear proportional relationship. The built-in PID algorithm of the microprocessor 5 can support most information processing requirements. The PID algorithm is widely used in industrial automation and process control fields, and its algorithm is simple and easy to implement. As a kind of closed-loop control algorithm, it can also be corrected according to the output feedback of the output control object, and can effectively correct the deviation of the controlled object, so as to reach a stable state.

[0031] Further, the bottom of the shell 1 is provided with a shock-absorbing base 11, and the shock-absorbing base 11 is internally provided with a rubber damping block 12, which has the beneficial effects that the shock-absorbing base 11 provided at the bottom of the shell 1 effectively reduces the vibration generated by the motor and the motor 4 in the operation of the stabilizer, reduces the relative sliding of the shell 1, improves the stability of the whole new stabilizer, and the rubber damping block 12 internally provided in the shock-absorbing base 11 is elastic and can absorb a certain impact force when deformed, further reducing the vibration frequency and impact force of the whole stabilizer, so that the stabilizer is more stable and safe in use.
