Load distribution principle of inverter in the application of electric drive
Load distribution principle is the requirement of each transmission point line speed, output torque of the two motors equilibrium. For load distribution requirements is not high driving the cart walking double motor, mechanical structure of double transmission of non rigid connection, by a frequency inverter and drive two motors drive two carts or motor with two inverters, set the inverter characteristic curve droop "function, the former mechanical behaviors of the two electric motors also softened, mechanical hardness tends to be close, a frequency converter drive several roller motor roller conveyor in a situation similar to this; the latter makes the mechanical characteristics of motor are softening, mechanical hardness more close than the former”.
Two drives can make the speed of tracking improved, the realization of load distribution of low precision. However, for large span cart driving traffic, packet trolley lifting, moving, must carry on the load distribution of high precision control. The method of load distribution is driven by two motors respectively with two inverters, from synchronous control using principal -- the main transmission link design for speed control, from the drive set for torque control. Torque from the inverter to follow the main inverter, thereby realizing the load distribution.
