Chapter (11) Synchronous Motors Introduction It may be recalled that a d.c. generator can be run as a d.c. motor. In like manner‚ an alternator may operate as a motor by connecting its armature winding to a 3-phase supply. It is then called a synchronous motor. As the name implies‚ a synchronous motor runs at synchronous speed (Ns = 120f/P) i.e.‚ in synchronism with the revolving field produced by the 3-phase supply. The speed of rotation is‚ therefore‚ tied to the frequency of the source. Since

EPHE 380 – Motor Control Final Exam Ian Haig V00711512 Scenario: Walking down a 45 degree slope with a surfboard under my left arm and a large mountaineering backpack on my back. I was walking down the trail to Sombrio Beach which is about a 1.5k hike down a steep trail to the ocean. I had a surfboard under my right arm‚ an axe in my left hand‚ and a large 40 litre hiking backpack fully loaded with supplies on my back. About half way down there is a left turn in the trail which has a declining

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

Motor Graders in Construction The motor grader is a large multipurpose machine used for many different construction operations. These many operations include but are not limited to: grading‚ shaping‚ bank sloping‚ ditching‚ and scarifying. Graders can also be employed to clear roads of snow and debris without doing any damage to the underlying roadway surface. Graders are much more “gentle” than dozers and other large pushing machinery. Motor graders are designed for preparing the substrate of roads

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
