Diesel Generator Starting Motor

A diesel generator generates electricity by using a diesel engine as the power source to drive the generator. However, the diesel engine needs to be started before it can drive the generator, so a starter, commonly known as a motor, is required to start the diesel engine. Currently, there are generally three types of motor starters for diesel engines: electric starting (motor starting), small gasoline engine starting, high-pressure air starting, etc. But many netizens often confuse motors, generators, and motor. There's no need to worry, as the editor from Dingbo Power Generator Manufacturer will explain this in detail for you.

In fact, there is a difference between a motor and a generator, but a motor and a motor are indeed the same thing. A motor refers to an electric motor, which is a device that converts electrical energy into power and rotates when energized; while a generator is a device that converts mechanical energy into electrical energy through other energy sources and outputs electrical energy when rotating.

"Motor" is the transliteration of the English word "motor", which still means electric motor or engine when translated. The principle of a motor being the same as that of an electric motor and a generator is actually the same, both based on magnetic induction. Although the principles of the two devices are the same, their structures are different, so there is no possibility of them being universal. Especially for high-power electric motors, their windings are all for excitation and cannot output current externally, so they cannot be mixed.

When we use diesel generator motors, various fault problems may occur. For example, it is quite common for the diesel generator starting motor to idle. The specific causes of the fault may be the following phenomena:

1.Insufficient suction of the electromagnetic switch

2.One-way clutch slipping

3.The teeth of the starter drive gear and the diesel engine flywheel are damaged or tooth jamming occurs

4.The shift fork inside the starter is damaged

5.The electromagnetic switch of the starter is closed excessively

How to troubleshoot the idling fault of the diesel generator set motor? The following solutions can be referred to:

1.Use a screwdriver to adjust the adjusting screw at the lower left end of the electromagnetic switch so that the distance between the gear and the ring gear is close and easy to engage.

2.Turn the flywheel to change the meshing position between the flywheel and the drive gear, and start again. If the starter still idles.

3.Remove the starter, inspect the inside of the starter, and if one side of the shift fork inside the starter is found to be damaged, weld and assemble it, then restart the diesel engine.
