Industrial Applications

1. Conveyor Belt Systems

The SINAMICS V20 drive can precisely control the speed of a 1.5 kW AC motor in a conveyor system, ensuring smooth material flow and preventing sudden stops or starts that could damage products.

Problem Solved

Provides precise speed control for varying production rates and enables soft start/stop to reduce mechanical stress and wear on the conveyor system. The 150% overload capacity is beneficial for handling momentary peak loads.
