Abstract

A multiphase motor comprises a rubbing ring rotor (LF) and a wound stator (ST) feeding a power supply (U1). There is a second power supply (U2) and a rectifier (SR) so that current is adjustable to give a variable rotary drive from zero towards the rated speed with little loss of efficiency : An independent claim is also included for a transport unit, especially a conveyor belt, driven as above.
