Abstract

PURPOSE:To make it possible to set different values of exciting currents respectively at the rotation and maintenance by a method wherein values of exciting currents flowing through a winding is compared with outputs of a reference voltage generator having an analogue switch used for selecting the reference voltage. CONSTITUTION:When a signal is fed as input to a terminal a, a transistor Tr1 is turned on through transistors Tr5, 6, a motor winding X1 is excited and at the same time the excitation is removed by the ON-operation of transistor Tr7. ON-OFF operations of the transistor Tr7 are carried out by comparing with voltages of an exciting current detecting resistor R5 and the voltages of a reference voltage generator which makes selection of the reference voltage, changing over the voltages set by setting variable resistors VR1, VR2, by means of a comparator COMP. Accordingly, the reference current values which are different according to the states of rotation and maintenance can be established and noises and other miscellaneous voices in the maintenance state can be arrested.
