  • Siemens Electric Motor Works
    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...

  • Siemens Electric Motor Works
    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...

  • Electric Motor Lab Report
    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...

  • Synchronous Motor - 4706 Words
    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....

  • Dc Motors - 702 Words
    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...

    Synchronous Motor Effects in Induction Machines1 BY E. E. DREESE2 Synopsis.-Many induction motors do not have the smooth speed torque curves which are to be expectedfrom elementary theory. Many motors at no load show a tendency to run at some speed way below that normally expected. This is sometimes called "subsynchronous" speed, or the motor is said to be "crawling." In the present paper one cause of this phenomenon is explained. It is found that certain combinations of phases, rotor slots,...
