Renesas offers highly integrated system-in-package (SIP) devices that are specifically designed to drive three-phase brushless DC (BLDC) motors commonly used in battery-powered power tools, gardening tools, drones, cordless vacuums, consumer robots, and cleaning robots.

Our ICs offer sensorless technology that leverages the analog circuitry and software to allow full torque at zero speed using sensorless motor control algorithms. This allows customers to eliminate the need for hall sensors, reducing the overall cost of the BLDC motor and improving product reliability.  

Renesas' sensorless technology can operate in high torque with zero RPM conditions. View our "BLDC Sensorless Technology for Zero RPM High Torque Application" video which presents a proof of concept using a popular cordless drill to screw and unscrew a lag screw in high-density wood.
