(MDK) 4 kW Board with

Intelligent Power Module

SPM31 650 V

SECO-MDK-4KW-65SPM31-

GEVB

Description

The SECO−MDK−4KW−65SPM31−GEVB is a development board

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 is rated for 400 Vdc input, delivering

continuous power in excess of 1 kW, with the capability of delivering

up to 4 kW power for a short period. 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.).

Features

• 4 kW Motor Control Solution Supplied with up to 410 Vdc

• Compatible with the Universal Controller Board (UCB)

FPGA−controller Based on Xilinx Zynq−7000 SoC

• Out of the Box Use Cases for FOC and V/F Control with Graphical

User Interface (GUI)

• Highly Integrated Power Module NFAM5065L4B 650 V/50 A
