Winding Temperature Rise

Heat from the losses inside an enclosed electric motor is properly dissipated into ambient air through the outer surface of the housing. In closed motors, this dissipation is usually assisted by the fan designed on the motor shaft itself. Favorable dissipation varies according to the efficiency of the ventilation system of the total dissipation area […]

Transformers Bearings

In the case of transformers having two windings, they are referred to as primary and secondary windings. In the case of transformers that contain three windings, the third is tertiary. There are also transformers that rely on only one winding. This means that the primary winding has a connection to the secondary winding, so that […]
