The detail that a force exists on a wire carrying a current in a magnetic field has an interesting application when we consider a current carrying loop. When the area vector is at right angles to the ...

Open-loop current sensors have a definite price advantage over closed-loop counterparts. While you can use them in drive applications where torque accuracy isn't demanding — such as pump and fan ...

The most common arrangement, which is used with only minor variations from small drives of say 0.5 kW up to the largest industrial drives of several megawatts, is the so-called two-loop control. This ...

Step motor control offers a powerful alternative in the right applications. Step motors are popular first and foremost because they are easy to use. They do not require an encoder to maintain their ...

Brushless dc (BLDC) motors are widely used in industrial and home applications, such as in HVAC blowers, because of their efficiency and cost advantage. Furthermore, sensorless control of BLDC motors ...
