The basic conditions for the formation of current are voltage and closed circuit. The prerequisite for generating shaft current is the presence of shaft voltage and a closed circuit.

A netizen mentioned that the winding of his single-phase motor overheated and was burned out. He plans to the number of turns in the main winding and asks whether the number of turns in the auxiliary winding needs to be adjusted.

It is really difficult to learn from a normal YE3 motor. If you learn from the analysis process of a faulty YE3 motor, it is really a shortcut and will involve every possible link. Today we share a case of scanning chamber failure. From this case, we can find some unsuitability of YE3 motor processing technology and operation process.

Shaft current is the main quality killer of variable frequency motors, large motors, high-voltage motors, and generators, which can cause significant damage to energy-saving motor bearing systems.

The stator and rotor of YS-H series marine three-phase asynchronous motors are supported by bearings to ensure that they have a relatively reasonable positional relationship in both static and operational states.

Corona is a common electrical fault phenomenon in high-voltage motors and variable frequency motors. Especially for high-voltage motors, when the rated voltage of YE3 motor is not less than 6kV, there are more occurrences of corona during the operation of YE3 motor. Especially in high-altitude, humid or corrosive gas environments, the corona voltage will decrease.

In marine environments, marine diesel generator sets face severe corrosion challenges. Salt content, humidity, and temperature changes in seawater can all cause corrosion of metal components, thereby affecting the performance and lifespan of power generation units. Shandong Ruihan will explore the corrosion issue of marine diesel generator sets and propose corresponding protective strategies.

A frequency converter is a device that converts power at the power frequency into power at other frequencies. The power frequency in our country is 50Hz. In the field of YE3 motors, in order to change the speed or other performance changes of YE3 motors, many YE3 motors use frequency converters for power supply.
