SS-100 — Inverter-Duty Induction Motors (Vector Control) up to 350 hp, 600 V
Country: · Model: SS-100
SS-100 are induction motors designed exclusively for supply from a frequency converter, with a power of up to 350 hp (about 261 kW) at a voltage of up to 600 V. In a closed loop with vector control the constant-torque range reaches 2000:1, and full torque is available at zero speed.

Description
A special geometry of the stator and rotor slots reduces heating and noise from the higher harmonics of the inverter switching frequency and removes tooth ripple in the torque at low frequencies. In an open loop a range of 1000:1 is achievable. For machine tool spindles there are versions with a constant-power zone up to twice the base speed. Base speeds are 3600, 1800, 1200, 900 and 720 rpm, and the versions are single- and two-speed. The rated frequency is 60 Hz, up to 133 Hz from the inverter. Frame sizes are NEMA 56–449 and special, and the core is made of electrical steel M-19, M-36 or M-45. Class B, F, H insulation with vacuum impregnation withstands PWM pulse voltage, and the enclosures are ODP, TEFC, TENV and A-TEFC with an independent fan for continuous operation at low speeds.
How to choose
Choose this series when the drive runs only from an inverter and a wide range at constant torque is needed. The enclosed version with a shaft-mounted fan is TEFC, and for continuous operation at low speeds A-TEFC is used. For speeds up to 40 000 rpm see Precision (Spindle), for limited length Waferthin at 1/10–75 hp, and for 30 000 rpm and up to 450 hp High Speed Air Cooled. Typical applications of SS-100 cover machine tools, lifting and conveying equipment, pumps, fans and elevators.
