Embodiment Construction

[0015] Figure 4 shows a vertical length cross-section of an embodiment of the motor of the invention for driving a rope disc.

[0016] The electrical machine shown in FIG. 1 has a stationary annular stator 1 with wound stator poles for generating a rotating field.

[0017] Furthermore, there is a rotatably mounted rotor 2 which has permanent-magnet alternating poles which are distributed annularly over the circumference. The permanent magnet 3 can consist of, for example, a ferrite material, a samarium-cobalt material or an iron-neodymium material.

[0018] According to the invention, the stator 1 consists of a plurality of separate stator segments 1a, 1b, 1c, 1d, 1e and 1f, which have respective current connections 4a to 4f. The current connectors and lines are only schematically shown here. When powered by three-phase alternating current, each stator section is prescribed a three-phase incoming line and a three-phase outgoing line, as shown in the winding structure in Figu...

Abstract

An electric motor having a stationary annular stator with wound stator poles and a rotatably mounted rotor having annularly distributed permanent magnets or electromagnets of alternate polarity, wherein the stator is composed of a plurality of separate stator segments with their own, preferably three-phase current connections, wherein each stator segment is supplied by way of the respective current connections from its own frequency converter.

Description

technical field [0001] The invention relates to an electrical machine with a stationary annular stator with wound stator poles and a rotatably mounted rotor with annularly distributed permanent magnets or electromagnets with alternating polarity. The invention also relates to a cable drive with a driven cable deflection disc. Background technique [0002] Electric motors are already used today in cableway drives, in particular lifts (cableways for people transport). FIG. 2 shows the winding structure of a "perpetually excited" synchronous machine according to the prior art, in which the stator is not divided into segments. [0003] Previously, in the event of a motor failure, its operation had to be switched over to, for example, an emergency drive that was also running, so that the ropeway system could run without load. The changeover work usually takes a lot of time, during which the passengers in the cabin or on the seats have to wait, which can make the passengers feel...
