Reference design for industrial motor drive combines latest technologies

Infineon Technologies AG has introduced a pretested industrial reference design which lessens the time to market significantly. The reference design is a general-purpose motor drive that provides a nominal power of 22kW and can be operated directly on a 380V to 480V Three-Phase grid. The design may be fully reused for customisation and enables customers to evaluate its products under real operating conditions. It is ideal for applications such as pumps, compressors, fans, and conveyor belts.

The design combines the company’s latest technologies in one system: It incorporates the EasyPIM 3B IGBT7 module FP100R12W3T7_B11 for high current and high-power density, the EiceDRIVER Compact 1ED3131MC12H for optimal EMI performance and low-power losses, as well as the XENSIV current sensor TLI4971-A120T5 for measuring high currents with minimal power loss. The CoolSiC mosfet IMBF170R1K0M1 with a blocking voltage of 1700V is the central part of the auxiliary power supply. The system also includes two microcontrollers – the XMC4800 for control and the XMC4300 for communication, incorporating a pre-installed software package for motor control. This combination enables the evaluation of these products in one design and experience their interaction.

To complete the modular approach, the system is optionally offered with a 3D-printed housing, which contains all electronic components and the cooling system. The housing comprises a touchscreen to display current operation conditions, as well as EtherCAT and USB interfaces for external connections.
