Abstract:
Self-propelling trolley assembly ( 100 ), comprising a battery ( 156 ); at least one wheel ( 111,112 ) which is driven by an electric motor ( 151,152;1 ), which electric motor is powered by said battery; a rotation position or velocity sensor ( 9 ) arranged to sense a rotation position or rotation velocity of at least one trolley wheel ( 111,112 ); a user interface ( 153 ); and a control unit ( 150 ) arranged to regulate the electric motor based upon input from said user interface so as to affect a rotation of said wheel according to particular drive patterns. The invention is characterised in that the control unit is arranged to implement at least a feedback assisted propulsion drive pattern, based upon information read from said position or velocity sensor; a free-wheeling drive pattern; and a rocking drive pattern, in that all of said drive patterns are implemented using different drive voltage patterns to said electric motor, and in that the electric motor is of a type in which the stator ( 2 ) comprises a number of stator ( 2 ) poles ( 7 ) which is not an integer multiple of a corresponding number of rotor ( 3 ) poles and in which the stator poles are subdivided into at least three magnetically and electrically identical subsets ( 8 ) that are mounted one after the other around the angular direction of the electric motor.

Claim (Index 10):
Self-propelling trolley assembly according to  claim 7 , wherein the trolley comprises a mechanical brake which is arranged to be activated by the control unit, and in that the said braking mechanism comprises activating said mechanical brake.
