The benefits for you

Versatile
All types of synchronous and asynchronous motors can be controlled. Optional motor encoders or mechanical brakes can be adapted.

Intelligent
Information from the electronic nameplate as well as braking and diagnostic data are transmitted directly to the inverter.

Simple
The intelligent, digital connection with a standardized hybrid cable enables the power supply - as well as data connection between decentralized inverter and motor.

Safe
Integrated safety function STO (Safe Torque Off) in PL e. Binary control or optionally via PROFINET®/PROFIsafe.

We have based the further development of our decentralized product portfolio on our MOVI‑C® modular automation system. MOVIMOT® flexible enables the decentralized inverter to be installed close to the motor in your system. With MOVIMOT® flexible, it's up to you whether you opt for synchronous or asynchronous motor technology.

The MOVIMOT® flexible decentralized inverter consists of an inverter and a connection box with field distributor function.

MOVIMOT® flexible is available in two versions . MMF1., the lean basic version, already comes with the full range of inverter functions, while MMF3. offers additional options that simplify installation and operation. These options include a load disconnector (with or without integrated line protection) and preparation for mounting an operator panel. A key switch with feedback contact can also be integrated.

Performance class 1 (size 1/1E) of the decentralized inverter enables performances between 0.55 and 2.2 kW (depending on the motor type) due to rated output currents of 2.0, 2.5, 3.2, 4.0 and 5.5 A. Performance class 2 (size 2/2E) with rated output currents of 7.0, 9.5, 12.5 and 16.0 A provides performances from 3.0 kW to 7.5 kW.

Properties

  • Motor types: Can be combined with synchronous/asynchronous drives (with/without encoder) from SEW‑EURODRIVE and with third-party motors
  • Encoder evaluation: Evaluation of all SEW‑EURODRIVE motor encoders with DDI interface
  • Connection voltage: 380 V – 500 V at 50/60 Hz (also available as IT system variant)
  • MOVILINK® DDI: The digital motor interface with an electronic nameplate that includes all drive unit data. By eliminating the need for manual motor startup, this saves you valuable time and avoids any potential startup errors.
  • Control modes
    • V/f: Highly robust for asynchronous motors without encoders
    • VFCPLUS: Extremely versatile for asynchronous motors with and without encoders
    • CFC: Highly dynamic for asynchronous and synchronous motors with encoders
    • ELSM®: Highly efficient for synchronous motors without encoders
  • Overload capacity up to 300% of IN
    • Prevents oversizing in static operation
    • Reduces installed size of necessary supply infrastructure
  • Weight (depending on inverter's drive electronics)
    • Size 1/1E: 3.5 – 5.5 kg
    • Size 2/12E: 9.5 – 10 kg

Quote

Tobias Nittel,
portfolio manager for decentralized drive technology at SEW‑EURODRIVE

The MOVI‑C® modular automation system gives customers the option to implement their applications both with inverters in a control cabinet and with drive electronics that are either located close to the motor or integrated into it without any differences in terms of project planning, handling or performance. An essential part of the platform is the digital motor integration. This supports automatic drive train startup and also ensures that various sensor signals can be transmitted from the motor to the electronics without requiring any additional installation work.
