 The driving force of the STELLAVOX-magnetic tape recorder SP 8 is a Stellavox servo-regulated direct current motor. The use of Samarium-cobalt for the stator as well as the special patented flat rotor are responsible for the high efficieny of the motor.
 
-The disc Shaped armature carries an axial commutator and a tacho-dise on its perimeter produces 400 bright-dark sectors, for the opto-electronic controlrange.
