Covers various types of Electrical machines: The working principles, operation, and applications of the different types of Motors, Generators and Transformers.
When selecting a motor for a specific industrial application, there are several factors and specifications that you should consider. We look at these factors that will guide you when choosing the appropriate motor for your industrial use.
The following are … Read more
A compound motor is a combination of a series and a shunt-wound motor.
The Speed-torque characteristics for a compound motor
Speed is … Read more
In the shunt motor, the motor winding is in parallel with the armature.
From the figure above, the supply current I = Ia + If . Unlike a series motor, if the load is removed … Read more
The dc series motor has its windings and armature connected in series across the supply.
From the figure above, the armature current Ia also supplies the field, hence when Ia is large on starting for … Read more
The effect of the force in a magnetic field may be used to cause the rotation of a motor armature. A single loop of a conductor shown in the diagram above has its ends connected to a simple … Read more
A transformer consists of several coils wound on a common core that usually consists of laminated iron (to reduce eddy-current loss).
Transformers are usually used to adjust the values of ac voltages. A transformer can step up or step down … Read more
A transformer is a device used to change the relative amplitudes of voltages and current in an AC circuit. A transformer consists of primary and secondary windings whose magnetic fluxes are linked by a ferromagnetic core. The principle of working … Read more
Motors convert electrical energy into rotational mechanical energy. Electrical motors are used to power many devices used in everyday life like refrigerators, washing machines, elevators, ventilation fans etc. Industrial applications include bulk material handling pumps, rock crushers, machinery operations, compressors, … Read more
