Toshiba three-phase brushless DC (BLDC) motor driver ICs provide excellent performance characteristics with or without position sensors. Sensor-based BLDCs are used when the initial load is unknown or it varies, or when high initial torque is required. Sensor-less BLDC motors are typically used in fans where they save Hall sensors and wiring. Typical applications include power tools, refrigerator/cooling (compressors) and HVAC (e.g. fan).
