FIELD: electricity.
SUBSTANCE: invention refers to electric engineering and can be used in converter systems, for example in DC electric fans. Non-contact electric DC motor includes constant magnet of rotor, position sensor on Hall element, two stator windings, transistor amplifiers, power supply, two separation resistors, inverter and emitter-follower amplifier, for example on transistor, which is connected to common bus of the device. Base of transistor of emitter-follower amplifier is connected to output of position sensor, and collector - to the first terminal in order to connect power supply, and output of emitter-follower amplifier is connected to integrated outputs of separation resistors. Emitter-follower amplifier can switch on resistance voltage divider or resistor in emitter circuit.
EFFECT: simplifying and improving reliability.
