Vacuum robot

Design high speed and robust vacuum robots with our code-free integrated BLDC motor drivers

Our integrated control BLDC drivers porfolio offers felixible options to fit different motor use case requirements, such as suction, brushbar and moping motors.

High suction power (up to 3-kHz electrical speed) and high startup torque capbility enables vacuum to stay at constant speed regardless of the floor conditions
Minimized power loses with ASR and AAR rectification techniques to prevent power losses and thermal dissipation
Lock-up detection to recognize an obstruction (sock) in the brushed bar that jams or locks up the bar from spinning
