Covers various types of Electrical machines: The working principles, operation, and applications of the different types of Motors, Generators and Transformers.
A key component of any motor control circuit is some kind of device to detect a condition of excessive overload…
Permanent magnet dc motors employ a permanent magnet instead of stationary field winding (as with the case of some other…
Testing is usually performed on DC machines to establish efficiency and power losses. A brake test is a direct technique…
Solid-state soft starting is the most commonly used technique for starting induction motors. It provides a smooth build-up of current…
A 3-phase autotransformer is typically employed where star or delta starting provides insufficient starting torque. Each phase of an autotransformer…
The AC motors works by rotating the stator field, they make use of the natural alternating nature of the AC…
Let’s consider an illustration of a typical three-phase direct-on-line (DOL) starter below: Figure 1 Three-phase direct-on-line starter When the start…
The cycloconverter provides direct ac to ac transformation with control over both the output voltage magnitude and output frequency. It…
AC and DC power isn’t new and yet it has been two main types of power we are taking advantage…
Introduction The transformer, in simple terms can be defined as the voltage regulator. It helps in stepping up and stepping…
