Unit modularity and small dimensions are important criteria when selecting a suitable frequency inverter. SEW Eurodrive is aware of these demands and, as a result, has developed a compact and economical successor to the MOVITRAC 31C - the MOVITRAC B. This inverter has been successfully applied in the waste, wastewater and sewage industries.
The new modular unit concept includes a number of enhancements such as, a higher overload capacity, improved motor performance through sensor-less flux vector control and separable terminals; offering greater functionality in a competitively priced frequency inverter.
Standard inverters in the MOVITRAC B range are designed for use with variable speed gear-motors without speed feedback. The power range from 0,25 to 2,2 kW for single phase 230 V a.c. and 0,75 to 132 kW three phase, 400/500 V a.c. means that the units can be implemented in a wide variety of applications, while complying with international requirements for various supply voltages and frequencies.
The MOVITRAC B's bookshelf-style format means that they have very compact dimensions, allowing optimum use of installation space in control cabinets. They are also equipped with an integrated cold plate for use in small on-site control cabinets that are installed close to the drive. Separate terminals for connection of the power supply and the motor, as well as practice-oriented mounting panels for EMC compliant cable shielded applications complete the features of the housing.
An integrated brake chopper and the line filter are also installed in the basic unit. The electronic control interface is connected via separate terminals and contains six binary inputs, two binary outputs, relay output and an analog set-point input. Additional interfaces including an analog output or additional analog inputs can be retrofitted thanks to the modular design. Although not a pre-requisite, an optional cost-effective keypad is available for parameter setting and start-up if required. The unit's application-specific and simple functionality means that all unit functions can be configured and initiated without any in-depth knowledge of the unit.
