专利汇可以提供Power source for commutatorless motor专利检索,专利查询,专利分析的服务。并且PURPOSE:To obtain a light-weight and small-sized commutatorless motor power source by removing a step-down transformer from a rectifying circuit, and magnetically coupling the output terminal of a rotating speed controlling circuit with a series constant voltage circuit of a DC stabilized power source circuit via a pulse transformer. CONSTITUTION:A step-down transformer is not connected to an AC power source 6, but the diode bridge 11 of a rectifying circuit 7 is connected directly to the power source, and the output terminal of the circuit 7 is connected to a DC stabilized power source circuit 8 having a series constant voltage circuit 30 and a smoothing circuit 17. A pulse transformer 50 is connected at the primary side coil via a transfomer 40 to the power terminal of a rotating speed controlling circuit 9, and is connected at the secondary side coil to the circuit 30. Since the transistor 20 of the circuit 30 is operated ON or OFF in response to the oscillation output of the circuit 9, the DC output voltage of the circuit 8 is determined, and the commutatorless motor is operated at the prescribed rotating speed.,下面是Power source for commutatorless motor专利的具体信息内容。
