Dynamic Dual-Source Ehps - 4.3xclht01 - 010 Energy Auto Parts

This dual-source rotary system combines high-voltage (400-700VDC, 3KW rated/7.5KW peak) and low-voltage (24VDC, 2KW peak) modular motors with a high-performance steering pump (10ml/r displacement, 13-13.7MPa). Featuring permanent magnet synchronous technology, 8-pole design, and robust IP67/H-class insulation, it delivers efficient power steering across -40°C to 85°C environments. The system's dual-voltage architecture ensures reliable operation under varying loads, enhancing vehicle control and safety with precise flow regulation (12±1.5L/min @1200r/min) and optimal energy efficiency (≥92%).

Product Description:
    Dual-source rotary products, integrated with high-voltage and low-voltage modular motor systems, are designed to meet the needs of diverse working conditions. High voltage module motor for 400 - 700VDC controller voltage, model EHPS - 4.3XCXJL01 - 010. With a rated power of up to 3KW and a maximum output of up to 7.5KW, it can operate stably at a rated speed of 1500r/min and can also work continuously at a working speed of 1200r/min. With 8-pole (4-pole) design, 92% ≥efficiency, insulation class H, protection class IP67, natural cooling method allows it to operate reliably in the environment of -40°C~ 85°C, and the permanent magnet synchronous motor type ensures high efficiency and precise control. The low-voltage module motor adopts 24VDC voltage and peak power of 2KW. It operates at a rated speed of 1200r/min and a rated frequency of 80HZ, and is also an 8-pole (4-pole) configuration. Line resistance 26.6mΩ, working system S2~3min, adapt to -40°C~ 85°C harsh environment, permanent magnet synchronization characteristics to ensure stable power output. The matching steering pump assembly model ZYB - 1312R/215/9WA - 2K, displacement 10ml/r, maximum pressure 13 - 13.7MPa, volumetric efficiency ≥ 80%. The control flow rate is 12±1.5L/min at 1200r/min and 9.6L/min ≥at 1200r/min and 11MPa. Dual-source synergy, this product can flexibly cope with different loads and working conditions, provide accurate, efficient and reliable power steering support for vehicles, and improve driving control and safety.
