Abstract

Considered nonsymmetric mode of drill bit oscillations when forming a unipolar electromagnetic torque on each cycle oscillations of dynamically balanced drill . Developed a method for estimating speed of rotation drill around its axis when working in the nonsymmetric mode at first approximation .

Keywords:
