SECO-MDK-4KW-65SPM31-GEVB: 4kW 650V Industrial Motor Control Power Board with Compact Intelligent Power Module (IPM)

The SECO-4KW-65SPM31-GEVB is a complete reference design for three-phase motor drives, part of the Motor Development Kit (MDK). The board features the NFAM5065L4B Intelligent Power Module in a DIP39 package and rated for 400 VDC input, delivering up to 4 kW of power. The board is fully compatible with the Universal Controller Board (UCB), based on the Xilinx® Zynq®-7000 SoC, which embeds FPGA logic and two ARM® Cortex-A9 processors. As such, the system is fit for high-end control strategies and enables operation of a variety of motor technologies (AC induction motor, PMSM, BLDC, etc...). The graphical user interface ensures an easy startup for evaluation purposes running voltage/frequency control. As part of the Motor Development Kit (MDK), the Compact IPM Motor Drive is compatible with the powerful Universal Controller Board (UCB), enabling high-end control strategies and AI capabilities for industrial motor control. The SECO-MDK-4KW-65SPM31-GEVK comprises of the SECO-MDK-4KW-65SPM31-GEVB and the Universal Controller Board (UCB).
