Title:
MAGNETIC GEARBOX
Document Type and Number:
WIPO Patent Application WO/2010/142962
Kind Code:
A3
Abstract:
A magnetic gearbox comprises a first rotor, a second rotor, and a rotatable pole piece member, wherein the first rotor is a magnetic rotor, the second rotor is a further magnetic rotor or a further rotatable pole piece member, and the rotatable pole piece member is magnetically coupled to at least one of the first rotor and the second rotor, at least one of the first rotor, the second rotor and the rotatable pole piece member is arranged for operation as a control rotor, each of the other two of the first rotor, the second rotor and the rotatable pole piece member are for coupling to a first, input shaft or a second, output shaft respectively, the control rotor is arranged so that in operation variation in the rate of rotation of the control rotor alters a gear ratio between the first shaft and the second shaft; and the gearbox further comprises gear control means for controlling the rate of rotation of the control rotor, thereby to control the gear ratio between the first shaft and the second shaft.
