Abstract

See full text

A method and apparatus for bearing replacement in an electrical machine is provided. An electrical machine is provided, comprising a stator with at least one stator winding, the stator defining a centre axis, and a rotor comprising magnetic material and having a first end and a second end. The electrical machine further comprises at least one bearing including a first bearing and supporting the rotor in an operational position in relation to the stator allowing the rotor to rotate in relation to the stator about the centre axis, and at least one support element including a first support element and adapted to support the rotor in relation to the stator such that the at least one support element in a support position supports the rotor centred about the centre axis, thereby allowing replacement of the first bearing, the support element in the support position being at least partly positioned between the rotor and the stator in a direction perpendicular to the centre axis.
