A drive unit for transport devices comprises a spindle (1) with a stator (2) and, mounted on said spindle so as to be capable of rotation, a rotor (3), all these elements forming an electric motor (4) and a rim (5). The device is provided with permanent magnets (6, 7, 8, 9), cores (10) with coils (1
A drive unit for transport devices comprises a spindle (1) with a stator (2) and, mounted on said spindle so as to be capable of rotation, a rotor (3), all these elements forming an electric motor (4) and a rim (5). The device is provided with permanent magnets (6, 7, 8, 9), cores (10) with coils (11), and sensors (12) for determining the angular position of the rotor (3). The rotor (3) is designed as concentric shells (13,14) and joined to the rim (5). The permanent magnets (6, 7, 8, 9) are mounted on the sleeves (13, 14), each magnet facing another magnet of opposite polarity; on each sleeve (13, 14) permanent magnets (6, 7, 8, 9) are mounted so that their polarity alternates. The stator (2) is located between the permanent magnets (6, 7, 8, 9) and carries the coils (11) with cores (10), the coils being connected around the periphery to the stator (2) and arranged with gaps between themselves and the permanent magnets (6, 7, 8, 9).

[ We claim:] [1.] A drive for transportation facilities, comprising an axle (1) with a stator (2) and a rotor (3) set rotatably on said axle to form an electric motor (4), and a rim (5), CHARACTERIZED in that it has permanent magnets (6, 7, 8, and 9), cores (10) with coils (11), and transducers (12)
[ We claim:] [1.] A drive for transportation facilities, comprising an axle (1) with a stator (2) and a rotor (3) set rotatably on said axle to form an electric motor (4), and a rim (5), CHARACTERIZED in that it has permanent magnets (6, 7, 8, and 9), cores (10) with coils (11), and transducers (12) of angular position of the rotor (3); the rotor (3) comprises concentric shells (13, 14) and is connected to the rim (5); the permanent magnets (6, 7, 8, and 9) are arranged on the shells (13, 14) one against the other so as to face each other with their opposite poles; on each shell (13, 14) the permanent magnets (6, 7, 8, and 9) are arranged with alternating polarity; the stator (2) is interposed between the permanent magnets (6, 7, 8, and 9) and carries the coils (11) with the cores (10), said coils peripherally connected to the stator (2) and arranged in a spaced relation to the permanent magnets (6, 7, 8, and 9); the rotor angular position transducers (12) are held in place on the stator (2) and are electrically connected to the coils (11) which are assembled into a winding (15) with two or more phases subdivided into phase zones having n coils which belong to the same phase, where n=1, 2, 3 . . . ; the coils (11) within the phase zones or all phases are spaced apart with a pitch differing from the pitch with which the permanent magnets (6, 7, 8, and 9) are arranged by a value equal to .alpha./n-1 . . . .alpha./n, where .alpha. denotes an angular width of a gap between the magnets (6, 7, 8, and 9) and the rotor angular position transducers (12) are interposed between the cores (10), one transducer per phase, in such a manner that with `n` being an even number, the transducers (12) are located on the outside of the stator (2) facing the permanent magnets (6, 7, 8, and 9) and along the axes of the phase zones, and with `n` being an odd number, the transducers (12) are displaced for an angle multiple of half the angular pitch of the permanent magnets (6, 7, 8, and 9) with respect to the axes of the phase zones.
