2/22/2024 9:05:00 AM

Summary: Brushless motor driven vacuum cleaner based on STDRIVE101.

EVLDRIVE101 HPD STMicroelectronics

The STMicroelectronics EVLDRIVE101-HPD reference design board is a three-phase, extremely compact brushless motor inverter based on the STDRIVE101 device and the STM32G071KB microcontroller. The board offers universal compatibility with multiple drive technologies, with FOC and ladder control, as well as sensored and sensorless. The EVLDRIVE101-HPD reference design board provides a ready-to-use and flexible solution to meet high output current needs in battery-powered three-phase applications. The board integrates fast power-up circuitry to facilitate seamless battery connection/disconnection, significantly extending usage time.

The EVLDRIVE101-HPD reference design board operates from 18V to 52V and has a 50mm diameter footprint. Typical applications include battery-powered home appliances, power tools, fans, industrial automation, drones and robots.
