3011-403-1-00
Product Overview
3011-403-1-00 is a standard frequency inverter from SEW-EURODRIVE MOVITRAC 3000 series with a rated power of 55 kW. It is designed for 3-phase 380–500 V AC industrial power grids. This is a 3-quadrant drive without regenerative braking function, so an external brake resistor is required for braking operation. Featuring sensorless vector control, it delivers stable speed regulation performance and is well-suited for conventional industrial loads.

Key Features
Standard 3-quadrant design. External brake resistors are needed for braking. It features simple structure and cost advantages, ideal for equipment without frequent braking demands.
Reliable sensorless vector control. It provides high torque at low speed and fast dynamic response. No encoder is required, which simplifies on-site installation and commissioning.
Comprehensive protection system ensures stable and long-term operation under harsh industrial working conditions.
Good expandability. An external EMC filter can be installed to meet relevant EMC standards, and optional fieldbus modules are available for network communication.
Typical Applications
This inverter is applied to drive 55 kW three-phase asynchronous motors. It is widely used for energy-saving speed regulation of industrial fans, water pumps and compressors. It also works for ordinary conveyors, roller tables, mixers, extruders and other constant-torque loads. It is the preferred choice for general industrial driving scenarios with no regenerative energy requirements.
