Magnetic gearing of permanent magnet brushless motors (Filed Oct. 22, 2004) Abstract A permanent magnet brushless 3-phase motor comprises windings R, Y, B, each divided into a plurality of sections 1-5 and switch means S1-S12 for selectively connecting the section of the respective winding e.g. R in series and/or parallel with all other sections of that winding R. Control means are provided for actuating the switch means S1-S12 to connect the winding sections 1-5 in different configurations whilst the motor is running to alter the speed/torque characteristics of the motor.
(0004) Canadian Patent Application No. 2341095 discloses an alternative to the above.......,
(0005) In the main embodiment of Canadian Patent Application No. 2341095, each of the motor windings comprises a plurality of series-connected sections..........,
