Abstract: The invention provides a process for the regulated control of an electric motor more particularly for an elevator, goods lift or storage installation.According to the method of the invention, along the path a coded strip (20) is disposed comprising evenly spaced marks which are read by a reader (23) fixed to the moving body.Counting means (29) give the absolute position of the moving body and means (30) are provided for calculating its speed from counting of the marks.These means are followed by the central processing unit (31) which sends to the motor a regulated voltage control.

Abstract: The invention provides a method for the regulated control of a moving body carrying a variable load driven along a predetermined path for slowing it down gradually and stopping it accurately at a given point, more particularly the car of an elevator installation.It is characterized in that:the possible slowing down references are all of different slopes and are defined as a function of the load carried by the moving body to be slowed down,the magnitude (G.sub.e) representative of the energy consumed is measured before entering the slowing down phase,it is from the estimated load (C.sub.e) that, for the slowing down phase of the moving body, the reference chosen from the set of references (20 to 23) is imposed as being the one having a slope suitable for the estimated load.
