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 ...

The NEC defines a controller in a few different ways. In Art. 100, a controller is described as “a device or group of devices that serves to govern, in some predetermined manner, the electric power ...

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: ...

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 ...

This file type includes high resolution graphics and schematics when applicable. Motors are rated by the output power they can produce over a given time period without overheating. These ratings are ...
