What are common faults in Electrical Motor?

If the electric motors have some kind of fault, It will mostly occur from the inadequate power supply. There are many other alignments and possible defects in DC and AC motors that lead to common faults.

The most common faults in AC and DC Electric Motors are as follows:

The Motor Is Not Mounted Correctly

Inadequate mounting of the electric motor can lead to defects when it is not correctly leveled as part of the installation process. If the housing is not properly bolted to the rest of the assembly or the surroundings, uneven stresses may arise which is also known as a soft foot.

The Electric Motor is Clogged With Dust

In physically dirty environments, the accumulation of dust inside an electrical motor can lead to short-circuiting. In dusty conditions, it is important to keep the surrounding area clean and to employ DIP (dust ingress protection) measures.

Water is Inside the Motor

Water ingress is a similar hazard — if liquids get into the terminal box or stator coils, short-circuiting will occur and the motor will burn out. In damp, humid, or wet areas, sufficient protection measures need to be deployed.

The Motor is Overheating

Overheating can occur if the electric motor is too small for the task, not fit for purpose or if changes to the load occur. High ambient temperatures are also a cause of overheating.
