Description
The LS have a shaft height of 56–225 mm. Single-speed versions are for 2, 4, 6 or 8 poles, two-speed for 2/4, 4/6, 4/8, 6/8 and 6/12. The LSES has class IE3 both on mains supply and on a frequency converter, meets the NEMA Premium level, shaft height 80–250 mm, with 2, 4 or 6 poles. The frame is aluminium, the shaft steel. Both series belong to the IMfinity platform, which covers 0.09–1500 kW in classes IE3 and IE4 in aluminium, cast iron or steel frames with IP55 or IP23 protection. Under EU regulation 640/2009 (ErP), IE2 class motors must work with a converter and have a second plate with data for drive setup. Braking resistors are offered for operation with a drive. Brake motors FCPL, FCR, FFB, FMD and gear motors adjoin these series. Supply voltage is up to 1 000 V.
How to choose
Power up to 45 kW is covered by the LS, and higher, up to 55 kW, or when IE3 from a converter is needed, the LSES is used. The number of poles sets the synchronous speed. The two-speed 2/4, 4/6, 4/8, 6/8 and 6/12 exist only in the LS. For powers from 55 to 900 kW look at the open motors PLSES.
