Rare Earth Application Industry Drive and Control System Solution

Elements such as lanthanum, cerium, praseodymium, neodymium, and yttrium—17 rare earth elements in total—possess unique atomic structures and exceptionally rich electron energy levels. This grants them superior optical, electrical, magnetic, and nuclear properties. Combined with their high chemical reactivity, they form a vast array of new materials with diverse functions and applications, earning the titles "the vitamins of modern industry" and "a treasure trove of new materials." Driven by the rapid growth of strategic emerging industries and the strategic goals of carbon peaking, carbon neutrality, pollution reduction, and carbon emission cuts, rare earth new materials and functional rare earth materials are seeing increasingly widespread and critical applications in sectors like new energy, advanced materials, high-end equipment manufacturing, energy conservation and environmental protection, rail transit, national defense, and 5G. The overall market for rare earths, rare earth new materials, and functional rare earth materials is projected to maintain an annual growth rate of 5%~10%, ensuring continued prosperity across the application industry. Key challenges in rare earth processing lie in transmission and control. Traditionally, mixing equipment in dissolution, extraction, and precipitation workshops relied on asynchronous motors paired with belt drives or asynchronous motors with inverters and motor stands. These setups involve multiple intermediate transmission stages, resulting in low operational efficiency. Mixers must operate at constant torque under wide-range low-speed conditions (e.g., 0~80 r/min, 0~100 r/min, 0~250 r/min, 0~300 r/min), where asynchronous motors suffer from significantly reduced efficiency and power factor. Furthermore, outdated control modules lead to unstable operation, low automation levels, and limited connectivity; most production lines lack integration with DCS systems or remote monitoring. Insufficient predictive maintenance prevents accurate collection of key parameters for safe and reliable operation, failing to meet full-lifecycle equipment O&M requirements. This solution replaces traditional transmission methods with low-speed permanent magnet direct drive systems. The TYCP5/TBYCP5 series low-speed permanent magnet direct drive motors cover frame sizes 180~560, offer rated power from 1.1~900kW, and support rated speeds of 25~500r/min. Rated voltage options include 380V and 660V. Efficiency meets GB30253 and GB1 standards. Standard duty cycle is S1 (with S2, S3, etc., available). Mounting configurations include V1 (B3 available). Insulation class is F (155℃) with H (180℃) available. Protection ratings range from IP55 (IP65, IP56, IP66 optional). Cooling methods include IC410 for H180~355 and IC70W for H400~560 (IC418, IC416, IC71W optional). The WD200 series high-performance vector inverters utilize advanced motor control algorithms, offering seamless matching with Wolong motors. They support asynchronous motors, permanent magnet synchronous motors, and synchronous reluctance control, featuring high reliability, performance, scalability, multi-drive capabilities, and ease of cabinet assembly. Available in power ranges from 0.75kW to 1000kW, these inverters support four power supply types. Their narrow-body design enhances cabinet flexibility, saves internal space, and reduces costs. The system employs ECC electrical cabinet control for centralized operation and data collection, integrates with DCS for process parameter scheduling, and optionally connects wireless temperature-vibration sensors and industrial Ethernet components to the Wolong Shunzhi Cloud Industrial Internet Platform for remote control, real-time monitoring, spectrum analysis, and remote fault diagnosis. A typical application case is Phase II technical renovation for a client in Jiangxi. The configuration includes TYCP5/TBYCP5 + WD200 (electrical cabinet) + remote monitoring (communication interface). The extraction workshop transitioned from asynchronous motor + belt drive to low-speed permanent magnet direct drive + inverter + DCS integration. The pretreatment workshop moved from asynchronous motor + inverter + stand to low-speed permanent magnet direct drive + inverter + DCS integration + temperature/vibration sensors. The precipitation workshop upgraded from asynchronous motor + motor stand to low-speed permanent magnet direct drive + inverter + DCS integration.
