Abstract (en)
[origin: ES8703385A1] 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.
