READ MOREBrushless DC Motors are an important class of highly efficient electric motors. They are most frequently used in electric vehicles because of their high efficiency and high power density. They are also present in the small DC fans used in power supplies and CPU coolers. In order to discuss the Brushless DC Motor it is important to first have a basic understanding of the more common Brushed DC Motor which is present in many household items. The brushed DC motor consists of a rotor (the

2.1 Motors use the effect of forces on current-carrying conductors in magnetic fields 2.1.1 The motor effect The motor effect is where a force acts on a current-carrying conductor in a magnetic field. The right hand palm rule is used to find certain properties: fingers point to magnetic field‚ thumb points in DC direction and palm points to direction of the force. 2.1.2 Factors affecting the force acting on the current-carrying conductor Forces are experienced by the electrons in the conductor

Design of Induction Motors Introduction: Induction motors are the ac motors which are employed as the prime movers in most of the industries. Such motors are widely used in industrial applications from small workshops to large industries. These motors are employed in applications such as centrifugal pumps‚ conveyers‚ compressors crushers‚ and drilling machines etc. Constructional Details: Similar to DC machines an induction motor consists of a stationary member called stator and a rotating

General Motors was founded in September of 1908 by William Durant during a time that there were less than 8‚000 in the United States. Durant was already known in Flint‚ Michigan for his horse drawn vehicles. “At its inception GM held only the Buick Motor Company‚ but in a matter of years would acquire more than 20 companies including Oldsmobile‚ Cadillac‚ and Oakland‚ today known as Pontiac.”(History & Heritage-Creation‚” 2014) General Motors set the tone in the automobile industry with design

Servo motor - This is a small motor in a C-band dish feed assembly. This motor selects whether vertical or horizontal polarization is to be received. Servo motor A Servo is a small device that has an output shaft. This shaft can be positioned to specific angular positions by sending the servo a coded signal. As long as the coded signal exists on the input line‚ the servo will maintain the angular position of the shaft. As the coded signal changes‚ the angular position of the shaft changes
