The control procedure, esp. for a micro-motor comprises a rotor with permanent magnets, and a stator with at least one winding linked electrically to control and feed systems. The magnets are positioned radially to induce a variable current (Ui) in the winding(s) defining a tension curve (106) which alternates over time. The rotation of the rotor is maintained by a series of successive pulses (102) which are provided in the respective alternations of the curve before the induced tension reaches an absolute maximum value in each alternation. The time interval (t1) between the curve passing zero and defining the start of one alternation and the beginning of a maintenance pulse (102) is constant, and determined so that the maintenance pulse intervenes before the induced tension attains the maximum value for a given reference speed. |
