Frequency inverter for motor speed control
11 July 2007
SEW-Eurodrive's new Movitrac LTE frequency inverter is designed and developed for speed control of asynchronous motors and performs its tasks in conveyor applications, (eg. in small, modular conveyor lines, in blowers and in pumps) in a particularly cost-effective way.
Whereas the Movidrive product series is used for more complex applications and Movi-Trac B serves as a standard inverter for a broad market spectrum, SEW-Eurodrive has also recognised the necessity to offer a drive for simple applications within the Movitrac product group: The Movitrac LTE.
The range of function of Movitrac LTE is perfectly matched to simple applications. Its user-friendly handling enables fast and easy integration; and fulfills the high quality standards of SEW-Eurodrive. Movitrac LTE is available in three sizes in the power range between 0.37 to 7.5 kW for single-phase (115 V and 230 V) and three-phase supply voltages (230V and 400V).
Other features include a total of 40 parameters which can be set, enclosures IP20 / NEMA 1 (control cabinet) and IP55 / NEMA 12k housing (for use outside of the control cabinet), quick installations and start-up, an integrated control panel for simple operation, an integrated EMC filer, and connection to fieldbuses via SEW gateways Ufx. Also featured is an integrated brake chopper in sizes 2 and 3, a compact design, and an external keypad (optional). The product meets compliance standards EN 61800-5-1, EN 61800-3, EN 55011
In addition to the standard design in enclosure IP20 for control cabinet mounting, a variant in enclosure IP55 / NEMA 12k is available for use in special ambient conditions. This allows the frequency inverters to fulfill their tasks reliably and flexibly also in dusty or wet conditions. Movitrac LTE will be available in all variants in October.
