Abstract
A serially connected double-phase full-wave brushless dc motor includes a first drive member, a second drive member, a first sensor member, a second sensor member, a first motor coil and a second motor coil. The first drive member is connected to a power source to thereby obtain a first voltage, and connected to the first sensor member and the first motor coil. The first drive member is further in serial connection with a second drive member and a second sensor member, and provides with a second voltage thereto. The second drive member is connected to the second sensor member and the second motor coil. Hall signals of the first and second sensor members are in control of an alternative direction of the first and second motor coils for conduction, and thereby the first and second motor coils are synchronously excited in full wave by the first and second voltages respectively.
