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
