PROBLEM TO BE SOLVED: To provide a motor for fuel pump capable of noticing heating of a coil part to a user, and to provide a method of controlling application of voltage to the same.;SOLUTION: A thermistor 36 is fitted to the top surface of a core 26 of a motor 14 for fuel pump, and the thermistor 36 is connected between a segment of a commutator 30 and a shaft 24. A display meter 46 capable of displaying potential of the shaft 24 is provided. Voltage of the current passed through the thermistor 36 from a plus side of a direct current power source 34 can be known by an indicator of the display meter 46. In the case wherein the temperature of a specified segment is lowered, voltage to be applied is temporarily raised to eliminate malfunction such as filming by a cleaning effect of rectified spark.;COPYRIGHT: (C)2010,JPO&INPIT
