1. Load characteristics:The mechanical punching machine drives the pulley to synchronize the gear to the gear through the shaft, and then uses the crankshaft to move the slider up and down to convert the curve motion into a linear motion. The load current impact is large, the inertia is large, and the load is abrupt. 2. Application requirements for the inverter:Smooth operation, simple control, and adapt to load abrupt changes. 3. Frequency conversion transformation advantages:After the transformation of the frequency converter, the impact of the large current on the power grid ...
