DRIVE UNIT FOR TRANSPORT DEVICES

Title:

DRIVE UNIT FOR TRANSPORT DEVICES

Document Type and Number:

WIPO Patent Application WO/1997/001379

Kind Code:

A1

Abstract:

The proposed 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 in the form of 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). The angular position sensors (12) are mounted on the stator (2) and electrically connected to the coils (11). The coils (11) are connected to the winding (15) which has two or more phases broken into phase zones of n-coils.
