and a motor in a circuit with two jumpers. 4. The theory was applied. The jumpers were connected to the alternate voltage supply. 5. The direction of DC motor was tested and determined. 6. 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

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

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

1. INTRODUCTION 1.1 PERFORMANCE APPRAISAL Performance appraisal is the process of obtaining‚ analyzing and recording information about the relative worth of an employee. The focus of the performance appraisal is measuring and improving the actual performance of the employee and also the future potential of the employee. Its aim is to measure what an employee does. It is a powerful tool to calibrate‚ refine and reward the performance of the employee. It helps to analyze his achievements and

INTRODUCTION GROWTH OF MOTOR INSURANCE Vehicle first appeared on the roads in United Kingdom (UK) during 1880’s‚ but the first motor insurance is issued during 1890’s. Therefore it is almost 10 years time people use a motor vehicle as a mode of transportation without insurance coverage. Therefore‚ through their (insurer) experiences on other classes of insurance such as fire‚ theft & liability‚ they introduce the motor insurance towards the use of transportation. Then they emphasis it (motor insurance) on

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
