Abstract:
A method of using an electrical machine, comprising:providing an electrical machine with a rotor (1) arranged on a rotary axle (2), a stator package (21) having a first stator section (22a) and a second stator section (22b) connected by a core (23) arranged to cooperate with a coil (24), the first stator section (22a) being spaced a distance (D1) from the second stator section (22b), a first permanent magnet (30a) being directed in a fist flux direction and a second permanent magnet (30b) directed in a second flux direction, the first magnet (30a) being attached to the first stator section (22a) and the second magnet (30b) being attached to the second stator section (22a), a first rotor pole (10a) and a second rotor pole 10b disposed on a rotor (11), the first rotor pole (10a) being spaced a distance (D2) from the second rotor pole (10b), the distance (D2) being different from the distance (D1); while positioning the first rotor pole (10a) directly below and aligned with the first stator section (22a) positioning the second rotor pole (10b) away from the second stator section (22b); and while permitting a first magnetic flux from the first magnet (30a) through the first rotor pole (10a) blocking any magnetic flux from the second magnet (30b) by the rotor disc (11).
