Abstract
A claw pole rotor for an electrical machine is provided, the claw pole rotor comprising a first claw pole component having a first yoke-shaft component to which at least two first claw pole fingers are connected, and a second claw pole component having a second yoke-shaft component to which at least two second claw pole fingers are connected, wherein the first claw pole fingers extend from a first side of the claw pole rotor towards a second side of the claw pole rotor, the second claw pole fingers extend from the second side towards the first side, and a magnet is arranged between the first yoke-shaft component of the first claw pole component and the second yoke-shaft component of the second claw pole component.

A claw pole rotor for an electrical machine, the claw pole rotor comprising:
- a first claw pole component having a first yoke-shaft component to which at least two first claw pole fingers are connected;
- a second claw pole component having a second yoke-shaft component to which at least two second claw pole fingers are connected, wherein:
- the first claw pole fingers extend from a first side of the claw pole rotor towards a second side of the claw pole rotor;
- and
- the second claw pole fingers extend from the second side towards the first side;
- and
- a magnet arranged between the first yoke-shaft component of the first claw pole component and the second yoke-shaft component of the second claw pole component,
- wherein:
- at least one magnet layer is arranged between the first yoke-shaft component and the second yoke-shaft component, wherein the at least one magnet layer, as seen in a cross-section through the claw pole rotor, is arranged at a radial position which differs from that of the magnet;
- and
- a magnetization direction of the magnet as seen in a cross-section through the claw pole rotor along a radial direction extends in an opposite direction as compared to a magnetization direction of at least one of the at least one magnet layer.
A claw pole rotor for an electrical machine, the claw pole rotor comprising:
- a first claw pole component having a first yoke-shaft component to which at least two first claw pole fingers are connected;
- a second claw pole component having a second yoke-shaft component to which at least two second claw pole fingers are connected, wherein:
- the first claw pole fingers extend from a first side of the claw pole rotor towards a second side of the claw pole rotor;
- and
- the second claw pole fingers extend from the second side towards the first side;
- and
- a magnet arranged between the first yoke-shaft component of the first claw pole component and the second yoke-shaft component of the second claw pole component,
- wherein:
- in a cross-section through the claw pole rotor, the magnet is arranged in a radial direction at least in some places between the first yoke-shaft component and the second yoke-shaft component.
A claw pole rotor for an electrical machine, the claw pole rotor comprising:
- a first claw pole component having a first yoke-shaft component to which at least two first claw pole fingers are connected;
- a second claw pole component having a second yoke-shaft component to which at least two second claw pole fingers are connected, wherein:
- the first claw pole fingers extend from a first side of the claw pole rotor towards a second side of the claw pole rotor;
- and
- the second claw pole fingers extend from the second side towards the first side;
- and
- a magnet arranged between the first yoke-shaft component of the first claw pole component and the second yoke-shaft component of the second claw pole component,
- wherein:
- the first yoke-shaft component, the magnet and the second yoke-shaft component are arranged to be coaxial with respect to one another at least in some places.
