Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude and frequency pass through a comparator and are ...

Speed control of an AC motor requires a three phase supply that can vary both voltage and frequency. Such a supply creates a variable speed rotating field in the stator that allows the rotor to spin ...

However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...

Regardless of their primary field, sooner or later, most designers have to deal with motor controls. Broadly speaking, there are two methods to incorporating these components in your design. First, ...

Since AC induction motors have been established as the preferred choice for industrial motors and the need for reduced power in all aspects of design is ever present, the efficiency of these motors is ...

Vector Control, also known as Field Oriented Control or FOC is an AC motor control scheme that enables fine-grained control over a connected motor, through the precise control of its phases. In a ...

Having reviewed the basics of BLDC motor control in Part 1, the design effort canbegin.. The first quest is to select a microcontroller. Looking in themarketplace there are several microcontrollers ...
