电磁控制强制啮合式起动机在起动时,起动齿轮与飞轮齿环的啮合初期由电磁开关依靠电磁吸力强制完成。为了确保电磁开关有足够大的电磁力,在任何情况下均能顺利啮合(包括顶齿),并使开关主触点导通,其始吸电压应远远地小于起动机额定电压。JB2741—80标准规定起动机的始吸电压应不大于额定电压的75%,即不大于9伏(12伏额定电压)与18伏(24伏额定电压)。起动时,由于消耗电流甚大,在蓄电池(包括导线)上的内部电压降达数伏,蓄电池亏
Electromagnetic control forced engagement starter at start-up, start gear and flywheel gear meshing initially by the electromagnetic switch to rely on electromagnetic force to complete. In order to ensure that the electromagnetic switch has sufficient electromagnetic force, in any case can successfully mesh (including top teeth), and the main switch contacts turn-on, the suction voltage should be far less than the rated voltage of the starter. The JB2741-80 standard states that the starting voltage of the starter should not exceed 75% of the rated voltage, ie no greater than 9 volts (12 volts nominal) and 18 volts (24 volts nominal). Starting, due to the large current consumption, the battery (including wires) on the internal voltage drop of several volts, battery loss
