The plasma mechanism of synchrotron knots’ formation discovered in the Crab Nebula at the distances 0″.65 (1016 cm) and 3″.8 (6 × 1016 cm) from the Crab pulsar is presented. The mechanism is based on exitation of cyclotron and Cherenkov-drift instabilities in the relativist s electron-positron plasma of the nebula. The higher luminosity of the knots is supposed due to the orientation of the direction of motion of the synchrotron radiation sources (Larmor circles) relative to the observer.
