ABSTRACT:
In order to create an economical drive unit for multiple shaft drive units for high speed loads that may be operated without wear and running noise, each drive shaft is designed as a rotor of a commutatorless direct current motor. One rotor of the unit is provided with a position sensor, all motors of the unit being connected in parallel with a commutating circuit, and all rotors being linked by a mechanical coupling of low power-transmitting capacity, such as a belt.
