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 during the previous power frequency startup is solved, the environmental pollution of the mechanical operation noise is reduced, the starting current is greatly reduced compared with the previous one, and the wear of the mechanical components can be significantly reduced, and the service life of the machine is prolonged. Reduce maintenance costs and shorten maintenance time, and the economic benefits are significant.

4. Note:

Due to the large inertia of the load on the punching machine, the braking resistor can be installed according to the site conditions.
