#CMT# #/CMT# The drive has a brake device, which exhibits a braking force depending on the output voltage (U A) of the generator-operated electric motor (M). The drain-source path of the field-effect transistor (T1) is arranged in the braking current circuit. #CMT#USE : #/CMT# For actuating a moving wing, particularly a door. #CMT#ADVANTAGE : #/CMT# Ensures that drive contains adjustable and constructionally simple brake device. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows the circuit diagram of the braking circuit for the electric motor. D : Drain D1 : Diode M : Electric motor T1 : Field-effect transistor U A : Output voltage. |
