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 9):
Self-propelling trolley assembly according to  claim 8 , wherein the generator mode is implemented by the control unit actively controlling the direction of induced currents due to the forced rotation of the motor rotor in relation to the motor stator and feeding said current to the battery for recharging the battery.
