This paper presents the design of a drive system for low-power fan. consists brushless DC motor (BLDC) and low-voltage inverter. The rotor is built four offset layers, inside which permanent magnets are placed. minimizes cogging torque machine guarantees trouble-free operation (no possibility breaking off). A lowvoltage inverter provides speed control over wide range limits motor's starting current. explains algorithm sensorless reducing price position sensors their wiring), compares legacy with new shows significant reduction in power consumption drive.
