One way an hvacr service tech can determine that s/he is making good motor replacement decisions in the field is to understand the concept of motor speed so that the speed of one ac induction motor ...

Demand for low-cost, robust motor drives has spurred increased use of sensorless vector control of induction and BLDC motors in everything from consumer Demand for low-cost, robust motor drives has ...

You can divide the world of electronic motor drives into two categories: ac and dc. A motor drive controls the speed, torque, direction, and resulting horsepower of a motor. A dc drive typically ...

The thyristor d.c. drive remains an important speed-controlled industrial drive, especially where the higher maintenance cost associated with the d.c. motor brushes (c.f. induction motor) is tolerable ...

Choosing the right motor and VFD type depends on a variety of factors, however, it is necessary to first look at how the characteristics of a motor change when the speed is reduced —Sponsored article ...

In today’s world, motors are ubiquitous, powering everything from household appliances to industrial machinery. The importance of optimizing motor control for energy efficiency cannot be overstated, ...
