A drive circuit for a sensored brushless DC motor, which has a rotably mounted rotor hub, comprises four legs. Each leg has a MOSFET and a diode configured to form four individual nodes. A first primary stator winding is coupled between the first and second nodes, while a second primary stator winding is coupled between the third and fourth nodes. A Hall sensor and an associated interface circuit which detects positions of magnets associated with the motor. As a result of the detected position, the drive circuit turns the MOSFETs on and off in a specified manner so as to rotate the rotor hub without the need for a snubber circuit.
