Problems solved by technology

[0007] In addition, even when the motor is turned on, and the pinion gear meshes with the ring gear, the relay contacts are not closed, so voltage is not fully applied to the motor, resulting in difficulty in starting the engine, that is, reduced engine starting performance
Continuous current flowing through the resistor to the motor can melt the resistor, which can prevent the engine from starting

Embodiment Construction

[0058] With reference to the accompanying drawings, especially figure 1 and figure 2 , shows the electromagnetic relay 2 installed in the motor circuit of the engine starter 1 according to the first embodiment of the present invention, wherein like reference numerals designate like parts. The engine starter 1 is used to start an internal combustion engine mounted in an automobile, for example. The electromagnetic relay 2 is used to supply current to the motor 3, and the electromagnetic relay 2 is also referred to as a motor relay hereinafter.

[0059] Such as figure 2 As clearly shown in , the starter 1 is equipped with a motor 3 , an output shaft 4 , a pinion carrier (described in detail later), an electromagnetic switch 5 , and a motor relay 2 . When energized, the motor 3 generates torque for rotating the output shaft 4 through the armature 3a. The pinion carrier is movable along the output shaft 4 . The electromagnetic switch 5 is used to push the pinion carrier awa...

Abstract

A normally-closed electromagnetic relay which may be used in controlling a supply of electric current to an automotive engine starter. The electromagnetic relay is equipped with a resistor and a shirt circuit. The short circuit is created by closing of relay contacts when a relay coil is deenergized to establish an electric connection between ends of the resistor to supply the current from a battery to an electric motor without flowing through the resistor and opened by opening of the relay contacts when the relay coil is energized to supply the electric current from the battery to the electric motor through the resistor. If a motor drive signal line leading to the electromagnetic relay is disconnected when the relay coil is kept energized, it will cause the short circuit to be established to ensure the supply of current to the motor, which also avoids the melting down of the resistor.

Description

technical field [0001] The present invention generally relates to an electromagnetic relay which can be installed in a motor circuit of a san engine starter and equipped with a built-in resistor, for example, which controls the starting current in the motor when starting the internal combustion engine, and bypasses the resistor after the internal combustion engine is started so as to Provide current to the motor at full voltage. Background technique [0002] A typical engine starter for starting an internal combustion engine installed in, for example, a car is equipped with a solenoid switch for pushing the pinion towards the ring gear of the motor and closing the main contacts in the motor circuit to The electric motor installed in the engine starter is supplied with electric current from the battery. [0003] When the motor is turned on (in other words, when the electromagnetic switch closes the main contacts), an excessive current called inrush current flows from the bat...
