Heavy duty three-phase IEC motors in iron casing, IE3 efficiency, IP55 series 1LE0143/1LE8143
ELECTRICAL CHARACTERISTICS
• IE3 efficiency in accordance with the IEC 60034-30 Standard
• Switchable voltages (220/380/440V) for sizes (AH80 to AH250), 440V for AH 280 and above at 60Hz.
• It widely exceeds the range of the standard for voltage and frequency variations, allowing values of (+/-10%) in voltage and (+/- 5%) in frequency.
• Possibility of Y - Δ starting in all construction sizes for voltages of 220V and 440V.
• Siemens motors are manufactured with thermal class F materials (155 ºC), but in their operation they only reach temperature rise B (130 ºC), allowing an overload thermal reserve.
• Type of service: S1
• Service factor at all powers (FS): 1.15.
• Ambient operating temperature: -15/40 ºC.
• Suitable to be driven with a speed variator
MECHANICAL CHARACTERISTICS:
• Housing and plates in gray cast iron, ensuring high resistance to mechanical stress and high vibration application.
• Rigid ball type bearings, double sealed and with C3 internal clearance. Completely closed and maintenance-free, with a useful life of up to 20,000 hours of continuous service.
• IMB3 and IMB35 execution in sizes (AH 80 to AH 315) and IMB14 (sizes AH80 to AH112).
• IP55 Mechanical Protection.
• Stainless steel nameplate.
• Metal cap for all sizes.
• Maximum safe speed for 2 poles up to 5,200 rpm (sizes 80 to 112), 4,500 rpm (sizes 132 to 200) and 3,600 rpm (sizes 225 to 315)
• Maximum safe speed for 4 poles up to 3,600 rpm (sizes 80 to 112), 2,700 rpm (sizes 132 to 180) and 2,300 rpm (sizes 200 to 315)
• Maximum safe speed for 6 poles up to 2,400 rpm (sizes 80 to 180) and 1,800 rpm (sizes 200 to 315)
• The overspeed is 1.2 times the maximum safe speed, not exceeding 2 min. duration.
ACCESSORIES ON REQUEST:
• PTC thermistors for winding protection.
• Heating bands with 115V or 230V supply voltage.
