The WMD2 Series Dual-Channel Motor Controller is a high-performance drive system engineered for applicationsdemanding independent, precise control of two motors simultaneously. Featuring dual isolated channels (WMD2-54Z100L-2U for 450–650V systems; WMD2-33Z60L-2U for 240–450V systems), it delivers 2×100kVA or 2×60kVA rated capacity with 235A rated output current per channel and 300A peak current (1 minute), enabling robust torque delivery for acceleration, climbing, or heavy-load operations.
Operating across dual voltage ranges (DC 450–650V / 240–450V), it seamlessly integrates with high-voltage and medium-voltage battery platforms. The liquid-cooling system (25L/min flow rate, max water temp ≤70°C) ensures stable thermal performance under continuous high-load operation, with standardized water ports (inner Ø14mm, outer Ø19–20mm) for rapid vehicle integration.
Advanced sensor-based vector control provides exceptional dynamic performance: speed control range of 1:1000, ±2.5% speed accuracy, 200% starting torque (10s), <10ms torque response time, and ±5% torque control precision. The output frequency range (0.00–800Hz) supports ultra-low-speed crawling and high-RPM applications. With ≥97% efficiency under rated conditions, it minimizes energy loss and extends operational range.
Comprehensive protection suite includes: ground short-circuit, phase loss, motor/controller overload, over/under-voltage, overcurrent, overtemperature, overspeed, stall, and more—ensuring safety in harsh environments. The compact aluminum housing (450×335×130mm, ~14kg) features structural sealing for dust/water resistance (IP67-level ingress protection), while the 24V control supply (9–36V wide range) ensures compatibility with 12V/24V vehicle networks.
