1 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

is to use the electric motor instead of gasoline one. An electric car is a car that powered by an electric motor rather than a regular gasoline engine. There are several major differences between gasoline and electric cars. First of all‚ “the electric motor will replace the gasoline engine” (“How Electric”‚ 2004). Secondly‚ “the electric motor is powered by a controller” (“How Electric”‚ 2004). Thirdly‚ “the controller gets power from the rechargeable batteries” (“How Electric”‚ 2004). In

2. General Electric uses a multifaceted approach to help make them one of the industries leaders in engine production. This approach includes resources both financially and managerially. Financially General Electric has invested $50 million in new engine technology‚ with an additional $1.2 billion to $1.4 billion being required to help them bring new engine designs to the forefront. General Electric has also received a $20 million grant from NASA in order for them to create the first tester UDF

Our Electric Bicycle Project I have added an electric power assist onto a GT mountain bike. With a 3 HP peak motor‚ it is much more powerful than typical electric bicycles. The basic motivation to build an electric bike was to have a fun and efficient and environmentally friendly way to stay out my car for short trips around town‚ and also as a silent trail bike for exploring the hills. I wanted to get some exercise - this bike can still be pedaled. When I first put this together it was even more
