Abstract: The invention concerns a method for stabilizing the motion of an articulated chain of a chain block, especially to prevent the formation of resonance oscillation of the chain, in which an articulated chain is led across a polygonal chain wheel with non-uniform pitch, which is driven by an electric motor. In order to create a method to prevent the formation of a resonance oscillation of the articulated chain, it is proposed that a periodic and/or stochastic and dampening actuating variable is superimposed on the velocity of the chain wheel (4) and the dampening actuating variable produces a change in the chain velocity so as to prevent a formation of a resonance oscillation. The chain drive with reduced polygon effect is characterized in that an electronic damper (8) is hooked up in front of the electric motor (2), which produces a control of the electric motor (2) such that a formation of a resonance oscillation of the articulated chain (5) is prevented.

Abstract: The invention relates to a method for determining the winding temperature (TW) of the stator winding of a three-phase AC motor, in particular a pole-changeable asynchronous motor. For determining the winding temperature (TW) of the stator winding of three-phase AC motors that have an unfavorable ratio of the active power to the dissipation power and react sensitively to temperature changes and changes in a main voltage, and for readily determining the heat dissipation power (PV) from the winding temperature (TW) of the stator winding, it is proposed to determine the reference temperature (TG) and the motor current (IM) simultaneously at consecutive points in time, and to determine the winding temperature (TW) by calculating step-by-step sequentially the change in the winding temperature (TW) at a point in time (tn) and adding this change to the winding temperature (TW) of the immediately preceding point in time (tn−1).

Abstract: A process and apparatus for determining a load on a lifting mechanism including a load measuring device and a three-phase induction motor operable for lifting and lowering the load. The effective power consumption of the induction motor is determined by the load measuring device based on a measured current and measured voltage of the induction motor. The measured effective power consumption is then compared with a reference power, which is calculated as the power output of the induction motor driving a nominal load of the lifting mechanism, to calculated an instantaneous load on the lifting mechanism. The inventive apparatus and process advantageously requires no modifications or additions to load carrying parts of a lifting mechanism or carrying gear and provides accurate real time measurement of the load.
