The invention describes a three-phase electrical drive machine comprising a stationary primary part (2) having a series of stator slots (3), in which stator windings (4) of the three phases (U, V, W) are arranged, with the result that a current flow through the stator windings (4) produces primary-part magnet poles, and a secondary part (5), which is capable of moving on a predetermined movement path in relation to the primary part (2) and on which permanent magnets (6) are arranged such that in each case one of their poles faces the primary part (2) and a series of secondary-part magnet poles results in the movement direction, wherein, owing to the interaction of the primary-part magnet poles, resulting from the current flow, with the secondary-part magnet poles, a movement of the secondary part (5) on the movement path is brought about. The invention provides for the ratio of the number of secondary-part magnet poles facing the primary part (2) to the number of primary-part magnet poles which are opposite them in a predetermined position of the secondary part (5) to be 19:12. |
