Abstract

The invention relates to contactless direct current electric motors and can be used in an electrical drive requiring to combine the qualities of a contactless direct current electric motor, namely, long service life, with high operating speed and performance which are inherent to commutator electric motors with a hollow rotor. In the direct current electric motor, comprising a hollow non-magnetic rotor with an anchor winding and a magnetic system based on one or more permanent magnets, a rotor includes an electronic switch with an inner rectifier, which switch is secured on the electric motor shaft, connected to the anchor winding and is powered by alternating voltage from the secondary winding of a rotary transformer which is mounted on the electric motor shaft. The primary winding of the transformer is mounted on the electric motor stator and is used for connecting to an external power supply via a frequency converter. The sensor of the motor rotor position is designed in the form of magnetically controlled microcircuits mounted, in the magnetic flux area of the permanent magnet, on the rotary switch surface which is perpendicular to the axis of rotation. The toroidal frequency converter is structurally combined with the stator of the rotary transformer.
