ST IHM007V1 User Manual
Universal motor control starter kit (phase angle partialization)
Features
■ Capacitive power supply
■ Two speed sensor nets
■ Current sensing circuit
■ Zero crossing network
Description
The STEVAL-IHM007V1 evaluation board is a
complete reference system for a universal motor
drive. The hardware and software of the kit are
ideal for the development of universal motor
drives or, more generally, phase-angle control.
The kit includes a PC GUI (graphical user
interface) which allows the user to choose
between an open or closed loop control type (PI
controller). The control parameters are easily
modified. The complete system consists of two
boards (the main board and the PC interface
board) and the PC GUI software, which also
provides current, firing angle, and speed
information from the board
