Abstract
The utility model relates to a multi-group electromagnet speed regulating system. It is characterized in that the multi-group electromagnet speed regulating system includes cylindrical rotors on an input shaft and soft magnet rotors on an output shaft. The cylindrical rotors connect with the output shaft through bearings. The soft magnet rotors include turntable bases, soft magnets and coils. The soft magnets are all in a fan shape and are winded with the coils. Turning directions of the coils on every two neighboring soft magnets are opposite. The soft magnets are distributed in a circumferential direction on the turntable base. Copper plates are arranged in positions corresponding to the soft magnets. Air gaps form between the copper plates and the soft magnet rotors. The group number of the soft magnets is more than one. The output shaft is provided with a conductive slide ring. An electric brush connects with the surface of the conductive slide ring in a sliding manner. The electric brush connects with a positive electrode and a negative electrode of a DC power source respectively. Compared with the prior art, the multi-group electromagnet speed regulating system in the utility model has two beneficial effects. First, since silicon sheets have low coercivity and high magnetic conductivity, a transmission torque is facilitated to improve. Second, rotate speed can be controlled very conveniently through a current regulator, thus, the torque transmission efficiency is facilitated to improve and the stable speed regulation of the system can be realized.
