Description
The FLSES belongs to the IMfinity platform, more precisely to the section of motors for demanding applications, where the LC series stands alongside it and the overall range reaches 1500 kW in aluminium, cast-iron or steel frames with protection degree IP55 or IP65. The FLSES itself has a shaft height from 80 to 450 mm, 2, 4 and 6 poles, a cast-iron frame, a steel shaft and IP55 protection. The motor is started directly from the mains or fed from a frequency converter. Cast iron gives the mechanical strength and durability needed on heavy machines and in the aggressive atmosphere of workshops. In continuous duty the higher efficiency of classes IE3 and IE4 saves noticeable electricity. The series is used at voltages up to 1000 V, and delivery is possible at short notice. On the basis of cast-iron FLS motors there are also explosion-proof versions FLSD, FLSN and FLSPX for ATEX zones, presented as a separate item.
How to choose
The first question when selecting the FLSES concerns the class, since IE4 pays back faster where the motor runs most of the year. Next the mains voltage is checked against the rated 230/690 V, and it is decided whether there will be a frequency converter. For lighter tasks up to 55 kW in clean rooms there is the aluminium LSES series at 0.12–55 kW. For large machines in protected IP23 design the PLSES at 55–900 kW corresponds, and when an efficiency above IE5 is needed, look at the Dyneo+ synchronous reluctance motors at 5.5–500 kW.

FAQ
Can the FLSES motor be fed from a frequency converter?
Yes, the motors are designed both for direct-on-line starting and for operation from a frequency converter, at a mains frequency of 50 or 60 Hz.
What frame sizes and pole numbers does the FLSES series have?
Shaft height from 80 to 450 mm, 2, 4 or 6 poles, power from 0.75 to 900 kW.
What makes the cast-iron FLSES frame better than an aluminium one?
Cast iron is stronger and more durable in corrosive and aggressive environments, so the FLSES is taken for heavy processes. Aluminium LS and LSES are lighter, but their range ends at 55 kW.
Are there explosion-proof motors based on the FLS series for ATEX zones?
Yes, on the basis of cast-iron FLS motors the FLSD, FLSN and FLSPX versions are made for explosive ATEX zones. They are presented as a separate catalogue item.
