STM8 and Triac Demonstration Board

STEVAL-IHM041V1 Universal Motor Driver with Speed Control Based on the STM8 and Triac (US Version)

STMicroelectronics

The STEVAL-IHM041V1 demonstration board is a Triac-based phase angle control for universal motor speed control using an STM8S103F3P6, 8-bit microcontroller, to set the conduction angle of the Triac. The STEVAL-IHM041V1 demonstration board may be operated in either open loop mode or in closed loop speed control mode, with an AC tach, Hall sensor or opto-sensor feedback. The open loop mode may also be used as a lamp dimmer. The STEVAL-IHM041V1 demonstration board is designed to operate from a 120 V/60 Hz mains, but may be easily modified to operate on other mains voltages by changing components in the power supply and motor voltage sensing circuits. Suggested component values for 230 V/50 Hz mains voltages are shown in the relevant bill of materials.
