The main motor comprises a main motor shaft, while the main engaging and disengaging gear comprises a main clutch, an input shaft of the main engaging and disengaging gear and an output shaft of the main engaging and disengaging gear. The main motor shaft is in mechanical connection with the input shaft of the main engaging and disengaging gear. The starting device comprises a starting motor and an auxiliary engaging and disengaging gear. The auxiliary engaging and disengaging gear comprises an auxiliary clutch, and input shaft of the auxiliary engaging and disengaging gear and an output shaft of the auxiliary engaging and disengaging gear. The output shaft of the auxiliary engaging and disengaging gear is in mechanical connection with the main motor shaft. The input shaft of the auxiliary engaging and disengaging gear is in mechanical connection with the starting device. Through the additional main clutch and the starting device, the generation of the greater impact current is avoided. The motor is stop under the unload condition, thus the power is saved, correspondingly the motor service life is extended.
Description
Technical field
The utility model relates to a kind of energy saver of mechanotronics, especially about the energy-saving control device of motor.
Background technology
At present, the power-economizing method of motor, mainly by mode such as frequency conversion at loading condition, regulate its power output, reach purpose of energy saving.Under many circumstances, generator loss quite a few from no-load running.--zero load--load--zero load for load ... the motor of mode operation, preferably energy-saving operating method is: load, and--shutting down--load--shuts down ... operational mode.But because the Fraquent start of motor all will produce the ten minutes adverse influence to motor and electrical network, as to the motor of no-load running is arranged, motor is not out of service, and its no-load current is the 30%-40% of full-load current, is equivalent to waste part energy; If after stopping motor operation, need restart again, the electric current that then at every turn opens motor be full-load current 5-7 doubly, i.e. loss huge electric energy, and will produce bigger temporary impact electric current, also can produce certain influence to electrical network and motor.
The utility model content
The purpose of this utility model provides a kind of energy saver of motor, this device is the starting current that solves the energy loss problem of motor no-load running and reduce motor, shortened the no-load running time of motor, thereby the corresponding useful life of having saved electric energy and having prolonged motor.
For realizing above-mentioned purpose, device of the present utility model: include starting device, main clutch, control device and main motor, described main motor comprises main motor shaft, described main clutch includes main clutch, main clutch power shaft, main clutch output shaft, and described main motor shaft and main clutch power shaft be mechanical connection mutually; And starting device comprises actuating motor and auxiliary arrangement of clutch, described auxiliary arrangement of clutch includes assisted clutch, auxiliary arrangement of clutch power shaft, auxiliary arrangement of clutch output shaft, described auxiliary arrangement of clutch output shaft and described main motor shaft be mechanical connection mutually, and described auxiliary arrangement of clutch power shaft and described actuating motor be mechanical connection mutually; Described control device is connected with described starting device, main motor and main clutch respectively.
The utility model is by setting up main clutch and the use method from main clutch, auxiliary starting device; burden when having alleviated empty load of motor; reduce power wastage extraly; improved the utilance of electric energy; and when electric motor starting, avoid producing bigger impulse current electrical network is produced influence of harmonic; since unloaded shutdown, the corresponding life-span that prolongs motor.
