The electronically-reversed DC motor eliminates troubles of mechanical wear and electric spark resulted from the sliding contact between the brushes and commutator surface. Its main technological feature is that at the end of motor shaft is installed a commutation signal generator rotating coaxially with the shaft. The said generator outputs high-freq modulated signal which controls the switch-on sequence and freq of the electronic switch, and thus the DC source applied to the electronic switch is fed to stator winding of the DC motor in the form of pulses. |
