The paper deals with a new drive system for different tape recorders. The heart of the system consists of an electronically controlled asynchronous high slip eddy current motor. The complete homogenous rotor delivers a highly uniform torque. The capstan shaft can be coupled to the rotor directly without mechanical damping by a flexible coupling with flywheel. Speed ratios of 1:16 are possible. The paper gives a description of an electronic control circuit and an analysis of the servo system.
