Electric Motor

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...

Dc Motors

A DC motor is a mechanically commutated electric motor powered from direct current (DC). The stator is stationary in space by definition and therefore so is its current. The current in the rotor is switched by the commutator to also be stationary in space. This is how the relative angle between the stator and rotor magnetic flux is maintained near 90 degrees, which generates the maximum torque. DC motors have a rotating armature winding but non-rotating armature magnetic field and a static field...

PiezoElectric Ultrasonic Motors

more than 30 years. • The first ultrasonic motor was introduce by v.v lavrinko in 1965. • An Ultrasonic motor is a type of electric motor formed from the ultrasonic vibration of a component, the stator being placed against another, the rotor depending on the scheme of operation. • Conversion of electric energy into motion by inverse piezoelectric effect. • To obtain the levels of torque speed characteristics of USM using conventional motors we require to add a gear system to reduce...

Dominion Motors

Problem Definition John Bridges, the chief electrical engineer of Hamilton Oil Company, has concluded through motor testing that DMC competitors Spartan Motors and the Universal Motor Company of Canada offer the first and second choice motors on the market, respectively. DMC’s position as the third choice could prove quite detrimental to its market share because Hamilton is the largest active oil company in Canada, operating over 30% of producing wells, and Bridges is extremely influential in...

Simple Electric Motor

How to Make a Simple Electric Motor Energy comes in many forms. Electric energy can be converted into useful work, or mechanical energy, by machines called electric motors. Electric motors work due to electromagnetic interactions: the interaction ofcurrent (the flow of electrons) and a magnetic field. Problem Find out how to make a simple electric motor. Materials Needed D battery Insulated 22G wire 2 large-eyed, long, metal sewing needles (the eyes must be large enough to fit the wire...

Modeling and Simulation Proportional-Integral (Pi) Controller for a Dc Motor with Improvement Performance.

TITLE: MODELING AND SIMULATION PROPORTIONAL-INTEGRAL (PI) CONTROLLER FOR A DC MOTOR WITH IMPROVEMENT PERFORMANCE. SUMMARY This report is about a simulation study of modeling classical control technique of dc motor drive with improvement in proportional-integral (PI) control which is used closed-loop operation to control speed of motor. The speed regulator uses a PI controller in order to obtain the electromagnetic torque needed to reach the desired speed. Current controller controls the...

Analysis of Dominion Motors

Dominion Motors Case Analysis What, precisely, is the problem here? The problem is that DMC's largest consumer of oil well pumping motors has ranked them the #3 supplier, and not only could this impact purchasing from this customer (Hamilton), other smaller companies follow this large company for their purchasing decisions, so that they get the benefit of copying their R&D decisions. What are the causes of the problem? Power companies implemented a graduated monthly base charge per HP...
