A MULTIDIRECTIONAL DRIVING BALL AND A METHOD FOR ROTATING A SPHERICAL BALL

摘要

The invention provides for a invention provides for a multidirectional driving ball (1) comprising a hollow spherical ball part (2). The multidirectional driving ball (1) is characterised in that the hollow spherical ball part (2) comprises rotor magnets (20) arranged inside the hollow spherical ball part (2) to form a rotor (21) of an electrical motor (22) driving the rotation of the multidirectional driving ball (1). The invention further provides for a method for rotating a spherical ball (2) of a multidirectional driving ball (1) to obtain a displacement between said spherical ball (2) and a contact surface (3) engaging a surface of said spherical ball (2) in a contact point (4).
