STEVAL-IHM013V1: 1.4kW, Universal Motor, 100 ~ 230VAC

This document provides details of the vacuum cleaner evaluation board, including jumper settings, load connections, and device and software features. In terms of both hardware and software, the tool is ready for use in the development of universal motor driving based on phase angle control.

This board implements a traditional design solution for a universal motor control circuit with a microcontroller as a driver. The STEVAL-IHM013V1 has been customized for vacuum cleaner applications, however it can be easily adapted for most home appliance or industrial applications based on phase angle control without speed closed loop control.

The electronic driver with TRIAC and microcontroller presented in this document is cost effective and easy for designers to implement. Analog solutions are being progressively replaced by microcontroller designs even in low-cost applications. This evolution is primarily due to the possibility of implementing a soft-start function which allows the equipment to fulfill IEC 61000-3-3 standard on inrush currents. Their advantages also include flexibility, using less external components and easy adaptation by simple software modifications.
