ABSTRACT:
Disclosed is a multiphase brushless DC motor of a concentrated winding type having shunt connection, and a control circuit. The brushless DC motor includes a rotor made up of a permanent magnet with M number of poles, and a stator operating in K number of phases by means of windings wound on N number of teeth, wherein the plurality of windings having the same excitation phases wound on the teeth, are each maintained in shunt connection so as to improve driving torque and a rotational speed. A brushless DC motor includes a switching section having a plurality of upper switching devices and a plurality of lower switching devices connected with each other in series. Each of the windings is connected between a common joint between the upper and lower switching devices, and a common joint between a lower power supply voltage and a plurality of upper power supply voltages.
