Embodiment Construction

[0034] Figure 1a An exemplary embodiment of a rotor 1 of a synchronous reluctance machine of a floor conveyor machine according to the invention is shown schematically in cross section. The rotor 1 comprises a rotor shaft 2 and four segments 3 of soft-magnetic or suitably highly magnetically permeable material, which are arranged on the periphery and are each spaced apart from one another by forming air gaps. . Seen in the circumferential direction, the segments 3 form, in their respective central regions, magnetic poles 5 which, when an external magnetic field is applied, attempt to utilize said magnetic field orientation, since at said orientation of these magnetic poles 5 there is a magnetic minimum reluctance. If an external rotating magnetic field is generated by the stator winding, the rotor 1 is carried by this field. Four magnetic poles 5 are arranged on two axes cut at right angles. In the present example, the material of the segment 3 has only a very low alloy fr...

Abstract

A truck has a synchronous reluctance machine serving as a travel driving device and / or a working device, especially a driving device of a working hydraulic device. The synchronous reluctance machine is provided with a stator (8) and a rotor (7), wherein the stator is provided with at least three phase windings (11) used for generating a rotating field and provided with a stator body made of a soft magnetic material of high permeability as a stator material, rotor has a rotor body made of rotor material which is made of soft magnetic material of high permeability, and the electric conductivity of the stator material is smaller than that of rotor material due to its material properties and or laminations.

Description

technical field [0001] The invention relates to mobile working machines with synchronous reluctance motors. In particular, the invention relates to a floor conveyor with a synchronous reluctance motor as a drive for a travel drive and / or a working device, in particular a drive for a working hydraulic device, wherein the synchronous reluctance motor has a stator and a rotor, The stator is provided with at least three phase windings for generating a rotating field and is provided with a stator body made of a soft magnetic material with high magnetic permeability as the stator material, and the rotor has a soft magnetic material with high magnetic permeability as the rotor material manufactured rotor body. Background technique [0002] So-called synchronous reluctance motors are known in the prior art, which are three-phase motors (Drehfeldmaschine) for 4-quadrant operation, wherein the three-phase motors can be implemented and operated as motors or generators and Implementat...
