Today’s high-efficiency furnaces rely on high-tech components to run efficiently. These high-tech components, in turn, rely on regular and routine maintenance to run in tip-top condition. Although ...

Next is the H-bridge, which resembles an H (Figure 2), which is used typically with a brushed DC motor. In addition to run, coast, and break operating modes, it can also reverse a motor. Simplified ...

Classic radial gap, stacked lamination stators. (Shown with and without windings.) As we look at catalogs of electric motors, we find them classified by power, speed, and torque. To a large extent, ...

So far we have tacitly assumed that the output voltage from the converter was independent of the current drawn by the motor, and depended only on the delay angle α. In other words we have treated the ...

Different types of motors need different types of drivers. Requirements for a variety of applications. Selecting the right motor driver is crucial to achieving the required functionality and ...

The motor calculations presented here apply to changing conditions of a blower motor when pulley adjustments are made. However, these calculations are useful wherever electric motors are used. These ...

The wide range of electric motors can be a confusing topic even without considering intelligent motor control. This brief overview is for those who think motors are only divided into two categories: ...

The first type of motor built is still in widespread use In the late 1800s, several inventors built the first working motors, which used direct current (DC) power. After the invention of the induction ...
