The motors included in this series are normally used for spindles, lathes, grinders, milling cutters, conveyors, roller ways,
pumps and centrifugal fans, in the textile industry, etc.
With optimised operating functions, this series of motors for
inverter duty has been developed focusing on the design of
the magnetic circuit built with low-loss magnetic laminations
and on the configuration of the magnetic circuit. The windings
are designed with special features that eliminate the inverterinduced harmonics that generate disturbance for the machine.
Fed with voltage that varies in relation to the frequency, the
motor runs at constant torque up to the rated frequency.
Instead, for higher frequencies it operates at constant power.
The windings are built with a leading brand wire with double
enamel, class H insulation made with high-temperature
resistant polyesterimide resins. Insulation between the phases
and to earth is optimised by the excellent insulating materials
used, such as Mylar and pure Nomex.
