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

Ten years ago our electric motor business was in real trouble. Low labor rates allowed the Eastern Bloc countries to sell standard motors at prices we were unable to match. We had become the high-cost producer in the industry. Consequently‚ we decided to change our strategy and become a specialty motor producer. Once we adopted our new strategy‚ we discovered that while our existing cost system was adequate for costing standard motors‚ it was giving us inaccurate information when we used it to

Background: The Electric Motor Works (EMW) was Siemen’s primary producer of low wattage alternating current (A/C) motors‚ which sales volume was contributed by 80% of standard motors and 20% of customized motors. Although the firm had started to alter their program and had expanded the business in 1974‚ they still could not decline the price sufficiently to compete with the lower labour rate in Eastern Bloc competitors. Instead of mass production‚ EMW changed their strategy to manufacture efficiently

Electric Motor The goal of this experiment is to build a simple electric motor and observe how it works. I will attempt to make it spin evenly by attaching it to a battery via jumper cables. The independent variable is the battery charge (1.5 V) and the dependent variable is how fast the motor spins. The lab doesn’t have multiple experiments for us to test this but I would hypothesize that the two variables would have a positive correlation: higher voltage‚ faster spin. I built my tiny motor

Global Explosion-Proof Electric Motors and Actuators Market 2014-2018 Electrical motors and actuators are an integral part of the Process Equipment industry‚ and are employed in pumps‚ compressors‚ and valves in order to drive and control the flow of the medium throughout the process line. To operate in an NEC-classified hazardous environment‚ explosion-proof electric motor and actuator enclosures must withstand an implosion or an explosion‚ restricting flame propagation between the medium and

employed for motion control are called drives and employ any of the prime movers such as diesel or petrol engines gas or steam engines hydraulic motors and electric motors for supplying mechanical energy for motion control. Drives employing electric motors are known as Electrical drives.

ultrasonic motor INTRODUCTION All of us know that motor is a machine which produces or imparts motion‚ or in detail it is an arrangement of coils and magnets that converts electric energy into mechanical energy and ultrasonic motors are the next generation motors. In 1980‚the world’s first ultrasonic motor was invented which utilizes the piezoelectric effect in the ultrasonic frequency range to provide its motive force resulting in a motor with unusually good low speed‚ high torque

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

SISTEMAS DC Motors Catedrático: Ing. Gustavo Mendoza Leal Alumno: Alfredo Valdés Cárdenas Introduction A DC motor is a type of electrical machine that converts direct current into mechanical power by means of a magnetic field. DC motors are widely used in field applications because of their many advantages over AC motors such as speed control‚ high starting torque‚ quick starting‚ stopping‚ reverse and acceleration and free from harmonics found in AC. Applications of DC motors include but
