<p>#CMT# #/CMT# The method involves determining and storing values of start energy during a ramp-up of an asynchronous machine (101) from an ideal state to a operating speed. The asynchronous machine is braked in a reverse operation with a braking energy that corresponds to the start energy multiplied with a correction factor. The correction factor takes a value between 0 and 1, and further braking of the asynchronous machine takes place by direct current (DC) brakes after braking the machine in the reverse operation. #CMT#USE : #/CMT# Method for controlling a stopping process of an asynchronous machine that is utilized for driving a tool or machine e.g. planing machine, milling machine, circular sawing machine, in a wood-processing industry. #CMT#ADVANTAGE : #/CMT# The method enables an effective braking of the asynchronous machine with less technical complexities, and hence controlling the stopping process of the asynchronous machine in a simple, effective, accurate, and improved manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a block diagram of an asynchronous machine with a device for controlling a stopping process of an asynchronous machine. 101 : Asynchronous machine 102 : Control device 103 : Network protection 104, 105 : Reverse protections 106 : Control line.</p> |
