AC Motor Speed Controllers

Seecotrol AC motor speed controller from South Eastern Equipment Co is designed to meet the requirement of speed control of AC induction motors at the most economic cost combined with the utmost reliability. These inverter drives provide an infinitely variable speed adjustment from zero to full rated speed operating from the normal AC single phase up to 3 HP and three phase 415 V 50 Hz from 3 to 100 HP. A variable frequency inverter power source as an adjustable speed system has been employed to control AC induction motors, since the AC motor speed is determined by the power source frequency. These controllers are available in capacities from 0.75 to 100 kW, chassis mounted and industrial enclosure. Features: energy saving by high efficiency; reduced operational cost; simplicity of power circuitry; reduction of noise; full torque at 5 Hz; reduction in speed and bearing load; multi motor operation possible; and very high input power factor eliminates need for power compensation.
