A New Concept for a Capstan Drive System for Professional and Home Tape Recorders

Authors: Stosberg, Arturo E.

Journal of the Audio Engineering Society · Volume 17 · Issue 4 · pp. 423–426 · August 1969

Abstract

A new drive system for tape recorders is described. The heart of the system consists of an electronically controlled asynchronous high-slip eddy-current motor. The completely homogenous rotor drives a highly uniform torque. The capstan shaft can be coupled to the rotor directly, without requiring mechanical isolation such as a flexible coupling driving a flywheel. Speed ratios of 1:16 are possible. The paper gives a description of the electronic control circuit.
