Abstract
Electric motor for driving members that rotate at speeds of greater than 40,000 revolutions per minute, includes a stator housing induction coils, a rotor supporting multiple permanent magnets and located coaxially inside the stator, and multiple Hall sensors integral with the stator and capable of detecting the position of one or more points on the rotor as it rotates in order appropriately to time the injection of the induction currents into the coils as a function of the position of the permanent magnets. The motor includes elements for deactivating all but one of the Hall sensors when the rotor speed of oration exceeds 40,000 revolutions/mm, elements for measuring the rotor speed of rotation as it describes each n-th revolution; and elements for bringing about in the next or (n+1) th revolution of the rotor the injection of the currents into the coils.
