... A solenoid is a long wire wrapped around a metal core which produces a magnetic field when electric current is passed through it. They are important because they create controlled magnetic fields and can be used to convert energy into motion. The fingers point in the direction of the current. The th ...

Analysis of an Economical BLDC Drive System
... Permanent-magnet brushless dc (BLDC) motor is increasingly being used in automotive, computer, industrial and household products because of its high efficiency, high torque, ease of control and lower maintenance. A BLDC motor is designed to utilize the trapezoidal back EMF with square wave currents ...
