Motor drive enables single-motor centrifuge

摘要

Indianapolis—Vertical, self-discharging, centrifugal separators must operate at high speeds for separation, then achieve high torque at low speeds for a scraping. Classic designs are complicated, involving two motors connected to the load with chains, sprockets, pinion gears, and clutches. One motor spins the rotor at highspeed during the separation cycle, the other, typically a gearmotor, must produce enough torque to break the solids free from the bowl wall during the discharge cycle.
