FIELD: electricity. ^ SUBSTANCE: contact-free DC motor comprises a permanent rotor magnet, three Hall converters with signal generators, three stator windings. The logical converter with its outlets is connected via inverters to the inlets of transistor amplifiers. The outlets of the Hall converter signal generators are connected to the inlets of the logical converter on three logical elements EXCLUSIVE OR, three inlets of the logical converter are connected to according outlets of the Hall converter signal generators, and outlets of the logical elements EXCLUSIVE OR are the outlets of the logical converter. Transistor amplifiers may be arranged on the basis of a bipolar transistor of n-p-n structure or on the basis of a field transistor of N-channel structure. ^ EFFECT: simplified design and increased reliability of a contact-free DC motor. ^ 3 cl, 2 dwg |
