Product Description
Based on the actual operating conditions at numerous cement production facilities, a specialized intelligent drive system for roller presses—featuring a low-speed, high-torque permanent‑magnet motor—has been designed and put into practical operation. This system adopts a “low‑speed‑to‑low‑speed” design concept: the permanent‑magnet motor delivers output at a low speed of 300–360 r/min (only 20%–23% of the original induction motor’s speed), which is then coupled with a two‑stage planetary gearbox to achieve low‑speed, high‑torque output, thereby enabling the system to… Shortened drive chain, low vibration, low noise, reduced wear, minimal temperature rise, high energy efficiency, and long service life. and a series of other advantages.
Advantages: This system seamlessly integrates the high reliability and energy efficiency of a high‑voltage, low‑speed, high‑torque permanent‑magnet motor; the torque amplification provided by a planetary gearbox; and the intelligent control and precise protection offered by a sensorless vector inverter. As a result, it delivers an efficient, energy‑saving drive for roller presses—characterized by low vibration and noise, enhanced safety and reliability, smart control, and adjustable speed. The cooling method is water‑cooled (IC3W7), with voltage ratings of 6 kV and 10 kV, and a rated speed range of 250 r/min to 500 r/min. Design and manufacturing can be tailored to meet specific customer requirements or actual operating conditions.
