Embodiment Construction

[0023] 1 and 2 are schematic illustrations of an embodiment of the drive device 10 . The drive has at least one linear motor, with at least one first primary part 1, 1' and at least one second primary part 2, 2' separated from each other by a secondary part 3 in a plane XY. The first primary part is located on a first side of the secondary part and the second primary part is located on a second side of the secondary part. As shown in Figure 1, the drive has two linear motors, the first linear motor consists of a first pair of primary parts 1, 2 surrounding the secondary part 3, the second linear motor consists of a second pair of primary parts surrounding the secondary part 3 The primary parts 1', 2' are formed. A linear motor is a synchronous motor, the primary part of which is excited by permanent magnets in the secondary part. Any known permanent magnets can be used. The primary part has a winding through which current flows in a known manner. When current is present, a...

Abstract

The present invention relates to the driving device (10), the method for driving this driving device, and the elevator (100) that is driven by this driving device to move persons or goods by at least one cage (20). The driving device is provided with at least one linear motor having a secondary-side part (3) between first primary-side parts (1, 1') and second primary-side parts (2, 2'). The driving device is provided with at least one compensating means (5) that acts by compensating normal force exerted against sucking normal force between each primary-side part and the secondary-side part.

Description

technical field [0001] The invention relates to a drive with a linear motor, an elevator with the drive and a method of operation of the drive. Background technique [0002] Known drives with linear motors do not have a braking function. Therefore, a special assembly must be used for parking braking and emergency braking in elevators with said drive. Contents of the invention [0003] The object of the present invention is to provide a drive with a linear motor which can at the same time perform a braking function. Another object of the present invention is to propose a working method of the driving device. A further object of the invention is to propose an elevator with such a drive. [0004] The technical scheme that realizes the object of the present invention is as follows: [0005] A drive device having at least one linear motor with a secondary part located between a first primary part and a second primary part, the drive device having at least one compensating m...
