Arrow adds resources for motor drive design

The resources help designers raise efficiency to meet stringent new classes for AC motors covered by IEC/EN 60034-30-1.

These are typically 5-50 kW, line-powered drives with DC bus voltage over 200 V.

As the minimum requirement for these is now rising from International Efficiency (IE) class 3 to IE4 and IE5, this means increasing system efficiency from 86.7 percent to 89.5 percent.

The white paper describes motor-control techniques and drive architecture, including commutation methods, power-stage topologies, gate driving, and techniques to mitigate interference.

The landing page provides the latest information about motor control ICs, power semiconductors, drivers, protection, and interference suppression, including documentation, reference designs, and product news.

Arrow’s new online resource for high-efficiency motor control is now live and provides a link to register and download the white paper free of charge.
