What is the failure of aluminum motor is often happened

The failure of aluminum motor can be divided into two kinds: electrical failure and mechanical failure. Electrical failures include failures of switches, fuses, buttons, stator windings and starting equipment; Mechanical failures include failures of bearings, housings, shafts, fan blades and end caps. Electrical and electronics engineers are burdened. They need to be familiar with various motor failures. Once a Marine motor fails, electrical and electronics engineers on board must accurately find out the cause and part of the fault in a short period of time, and use motor theory to compare and analyze different faults, eliminate unrelated factors, and find the cause and part of the fault. The following tools are used to determine the steps of a faulty body:

1. Master the operating state, structure, specifications and working mechanism of the aluminum motor. During the normal operation of the aluminum motor, please always pay attention

 to its operating status. If there is a motor anomaly (such as a sudden increase in motor temperature and abnormal motor sound), the electrical electrician should repair it immediately.

2. After the failure of the aluminum motor, please carefully observe many abnormal clap phenomena (such as sound, vibration, temperature, smoke, speed, odor, power supply voltage 

and current, etc.).

3. When the abnormal phenomenon of the aluminum motor fault is not obvious, special instruments should be used for troubleshooting to find out the specific cause and location of the 

fault.

In troubleshooting, electronic electricians should first accurately distinguish the type of motor fault (electrical fault or mechanical fault). This is a simple way to determine: briefly turn on 

the motor power, and then disconnect the power. If the fault exists in both the on and off phases, the fault is a mechanical fault. If it exists only when powered on, it is an electrical fault.
