onsemi SECO-MDK-4KW-65SPM31-GEVB Motor Development Board

onsemi SECO-MDK-4KW-65SPM31-GEVB Motor Development Board is designed for three-phase motor drives and is part of the SECO-MDK-4KW-65SPM31-GEVK Motor Development Kit (MDK). The Dev Board features the NFAM5065L4B Intelligent Power Module in a DIP39 package. The Motor Development Board is rated for 400Vdc input, delivering continuous power over 1kW, with the capability of delivering up to 4kW power for a short period.

The onsemi SECO-MDK-4KW-65SPM31-GEVB 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. The system is fit for high-end control strategies and enables the operation of various motor technologies (AC induction motor, PMSM, BLDC, etc.).
