Abstract

PURPOSE:To block the DC offset current to load, by constituting the amplifying circuit with the first drive circuit in linear operation according to input signal, first switch circuit, and the second drive circuit and second switch circuit in linear operation with opposite phase from them. CONSTITUTION:The PNP transistor Tr15a and NPN transistor Tr15b in opposite polarity each other and PNP transistor Tr16a and NPN transistor Tr16b are connected in complementary manner, forming a pair of single end push pull circuit. The stator coil 2 of the linear drive brushless motor 1 is connected between the output terminals of those circuits. With this constitution, the drive signal e1' and the inverted signal e1' of the position detecting element 4 of the motor 1 are fed to the base of Tr15a and 16a, and the inversion signal s1 inverted s1 are fed to the base of Tr15b and Tr16b. Thus, no offset current flowed to the coil 2 and the level adjustment of the neutral point is not made necessary.
