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 16):
Self-propelling trolley assembly according to  claim 1 , wherein the trolley is arranged with a dead man's switch, and in that the control unit is arranged to apply a braking mechanism in case the dead man's switch is activated when the control unit is powered and the information from said position or velocity sensor indicates that the trolley is currently moving.
