These systems should have wire rated for a minimum of 1600 volt spikes, F or H class insulation, and will be processed with 100% sold resin in a vacuum pressure impregnation (VPI) system. NEMA Severe-Duty IEEE 841 AC Motors. Burned Out Motors and Variable Frequency Drives rated for at least 1,000 volts. MOTOR:DesignNEMA B - Three Phase Torque Curve NEMA L - Single Phase Torque Curve Oil-Filled, Squirrel Cage Induction, Inverter Duty rated per NEMA MG1 InsulationClass H Varnish & Magnet Wire SINGLE PHASE Requires overload protection to be included in control panel. While T-Codes are not required for motors in Class I locations, putting a T-Code on the datasheet isn’t a bad idea. 15 Service Factor n Class B temperature rise n. 2) continuous duty (Duty type: S1) of the motor with its rated power PN, corresponding with the rated torque. Insulation Class shall be minimum Class F. THREE PHASE LV MOTORS. They are considerably more expensive than similarly rated TEFC motors. withstand severe voltage stresses. 2500 Full Load Efficiency Rating. Example, Class B (80 C) rise on sine wave, the motor at rest TEFC Inverter Duty. MOTORS® brand inverter duty motors? If so, could you please explain it. This gives more flexibility in choosing frame sizes. Nota: Devido ao isolamento especial, o Inverter Duty não necessita de reatores ou quaisquer outros filtros entre o inversor e o motor, para a proteção do sistema de isolação. 37kwto355kw(FramesE80toE355LX) SLIP RING MOTORS 22 kw to 160 kw (Frames EW 250 M to EW 315 L) STANDARD SPECIFICATIONS VOLTAGE FREQUENCY INSULATION RATING/DUTY MOUNTING PAINT AMBIENT / TEMPERATURE RISE TEMPERATURE CLASS : T4 DEGREE OF PROTECTION: 415 ± 10% Other Voltage class (220 V - 660 V) available on request. Electric Motor Sales Inc. Group A includes only acetylene, a colorless hydro-carbon gas that creates an intense explosion when ignited.
