SEW MOVIDRIVE MDX61B0075-5A3-4-0T | 7.5kW 4-Quadrant Inverter Drive

Overview

If your application involves cranes, hoists, or any equipment that needs to actively manage braking energy rather than just dissipate it, the SEW-Eurodrive MOVIDRIVE MDX61B0075-5A3-4-0T is built with exactly that in mind. This 7.5kW (10HP) drive runs full 4-quadrant operation with an integrated brake chopper, meaning it can drive a load in both directions and handle regenerative braking energy efficiently — no bolt-on brake resistor circuit required for basic energy handling.

It accepts a 3-phase 380–500VAC input at 50/60Hz and comes with built-in radio interference suppression for cleaner EMC performance in sensitive installations. Control options span V/f control and sensorless vector control, both running within the 4-quadrant regenerative framework, so you get flexibility in how precisely the motor is controlled while still keeping the braking benefits. Protection is thorough too — overload, short-circuit, over/undervoltage monitoring, and integrated brake energy handling all come standard.

As a Size 2S drive in an IP20 enclosure with integrated fan cooling, it’s built for vertical control cabinet mounting and rated for 0°C to +50°C ambient operation. At approximately 6.22kg (13.71 lbs), it’s manageable for standard panel installation, and it stays expandable via SEW’s communication modules (PROFIBUS, CANopen, EtherNet/IP) along with encoder feedback and custom I/O card support.
