ABSTRACT:
A friction driven tachogenerator having a friction drive wheel in contact with a movable member. The tachogenerator is compliantly and frictionlessly mounted, and at least one pressure roller is disposed in tangential, rolling contact with the friction drive wheel. The pressure roller biases the friction wheel against the movable member to provide a predetermined contact pressure between the friction wheel and movable member without applying a significant load to the shaft and bearings of the tachogenerator. The compliant and frictionless mounting of the tachogenerator is devoid of friction sources which can interfere with the sensing of velocity oscillations by the tachogenerator.
