Drive device
A drive device for a working machine for heavy industry, particularly for the raw-materials and mining industry, includes a permanent-magnet-excited motor and a frequency converter, wherein the motor has a rotor and a stator, and wherein the motor is a segment motor, in the case of which the rotor and/or the stator is composed of a plurality of segments, where considerable improvement in the availability of the motor is achieved because the motor has a segmented design, whereby the reliability during operation of the drive device is also increased.
1. A drive apparatus for a processing machine for heavy industry, comprising: a motor excited by a permanent magnet, the motor including: a rotor mounted on a bearing element having a horizontal axis of rotation, a single coupling bearing mounted on the bearing element, and a stator mounted on the bearing element; wherein the motor comprises a segment motor, in which at least one of (i) the rotor and (ii) the stator is composed of a plurality of segments.
2. The drive apparatus as claimed in claim 1 , further comprising:
a frequency converter;
wherein the segments of the stator are suppliable with electrical current by the frequency converter individually.
3. The drive apparatus as claimed in claim 1 , wherein the segments of the rotor are arranged in a circular manner.
4. The drive apparatus as claimed in claim 1 , wherein the segments of the stator are assembled to form a stator with a partially circular shape.
5. The drive apparatus as claimed in claim 1 , wherein the segments of at least one of (i) the rotor and (ii) the stator are fastened to a load-bearing structure of the motor.
6. The drive apparatus as claimed in claim 1 , wherein the bearing element is a rotatable shaft, the rotor is mounted on the rotatable shaft in a rotating manner and the stator is fastened to the rotatable shaft in a stationary manner.
7. The drive apparatus as claimed in claim 1 , wherein the bearing element is a fixed axle, the rotor is mounted on the fixed axle in a rotatable manner and the stator is arranged on the fixed axle with a fixed position.
