the purpose of lightening and power the field of electric motors especially the AC type has shown a remarkable development in all prospects all over the world. As a result of the technological advancements the engineers throughout the world tried their best of best to come out with the most energy efficient and safe machines particularly‚ in the context of electric motors. In this report we will confine our discussion up to electric motors‚ their construction‚ operations‚ applications‚ performance

All switches were in closed position at initial condition. 7. Only switch 1 and 4 was closed at the first condition as in figure 2(a). The direction of DC motor and the RPM of DC motor was recorded 8. Switch 1 was opened and switch 2 was closed as in figure 2(b) after the first reading was recorded. The motor was

ELECTRIC MOTORS I. Introduction Electric motors are considered to be important mechanical devices. They usually convert the electrical energy coming from the mechanical device into its kinetic energy to make it work (Petingco and Resurreccion‚ 2011). In this exercise‚ the students were tasked to use an example of an electric motor‚ identify its parts‚ and make it work. All electrical motors are equipped with stator and rotor. Stator is known as the stationary part of an electric motor while

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

The Path Forward: LIT MOTORS This report considers the strategy for Lit Motors; a San-Francisco based electric car start-up with two prototype vehicles in development. The Lit C-1 is the flagship product described as an enclosed‚ two-passenger‚ electric-powered‚ two-wheeled “daily driver”. The Lit Cargo Scooter folds to a small footprint when not in use and provides additional cargo space compared to normal scooters. The president and founder of Lit Motors is Daniel Kim‚ an erstwhile science and

1. What do you think of Mr. Reynolds’ management methods in general? I think that Mr. Reynolds’ management method is very trusting and his style is somewhat laissez-faire‚ making it a somewhat fragile system. Reynolds doesn’t require paperwork which is usually used to detail and keep track of each employee’s actions but instead relies on trust and maturity amongst the salespeople. Generally such a method is a very risky but it seems that the intensive training that the employees receive builds

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
