Siemens electric motor works case analysis

Laser Machining Inc Sumerset Wisc. Business Unit Level Solution - The case study may put you in a position of a marketing manager of a small brand. But on those applications mechanical load and the speed range must be considered, because on those applications motors can get very hot very fast.

Historically, PMs could not be made to retain high flux if they were disassembled; field windings were more practical to obtain the needed amount of flux.

AC motor starters are intended to start and accelerate motors to normalspeed, to ensure continuous operation of motors, and to provideo protection against overloads switch power of if overload occurs. This comprehensive section is prepared as a resource for individuals and professionals interested in the electrical engineering career path.

A commutated DC motor has a set of rotating windings wound on an armature mounted on a rotating shaft. While most commutators are cylindrical, some are flat discs consisting of several segments typically, at least three mounted on an insulator.

Please place the order on the website to order your own originally done case solution. Some of those motors need capacitor start unit which connect the starting capacitor to motor when it is powered up and disconnects that capacitor when the motorhas started.

An AC induction motor can consume more energy than it actually needs to perform ot's work, particularly when operated at less than full load conditions. The BLDC motor's characteristic trapezoidal counter-electromotive force CEMF waveform is derived partly from the stator windings being evenly distributed, and partly from the placement of the rotor's permanent magnets.

Depending on background and expertise, projects can include systems such as energy transmission and distribution, protection and control etc.

Electric motor

Whereas SCIMs cannot turn a shaft faster than allowed by the power line frequency, universal motors can run at much higher speeds. In addition to protection and control, some form of reliable method of isolation between the mains network and the motor, to be able to disconnect the power in case of problems exist or the device needs to be repaired.

There are variable frequency drives that allow induction motors to run on different speeds.

Siemens Electric Motor Works (A): Process-Oriented Costing Case Solution & Answer

They are also commonly used in portable power tools, such as drills, sanders, circular and jig saws, where the motor's characteristics work well. Conventry Convergent Energy, Inc. Drawing a motivation chart of the key players and their priorities from the case study description.

Field windings are dark copper-colored, toward the back, on both sides. There are many specific safety related regulations on this kind of switching devices. Evaluate each detail in the case study in light of the HBR case study analysis core ideas.

Case Studies

New Cost System Siemens that had adopted traditional system to reduce the cost could not come to a solution, but later it realized that some cost associated with some part of production were not captured by the traditional system.

Kaplan. Source: Harvard Business School. 7 pages. Siemens Electric Motor Works - 4 Two years after the change in strategy, problems with the traditional cost system became apparent. Management’s concern with the traditional cost system was its inability to capture the relation between the increased support costs and the change in product mix.1/5(2).

Traditional Costing system refers to the system adopted by Siemens Electric Motor Works. The strategy did not work, as some problems appeared in traditional costing system, where it could not capture the relation between the increased support costs, and the change in product mix.

Electric motors and transformers are usually reliable pieces of equipment, but inadequate motor and transformer maintenance can result in trouble.

Siemens Electric Motor Works (B): Pricing Interdivisional Sales HBS Case Analysis

Siemens Electric Motor Works’ strategic reorientation in the early s toward production of custom electric motors is a classic case study in process costing. Broadly, it demonstrated the importance of appropriate costing methodology in ensuring managers are using accurate information to make production decisions.

A linear induction motor (LIM) is an alternating current (AC), asynchronous linear motor that works by the same general principles as other induction motors but is typically designed to directly produce motion in a straight line.

Characteristically, linear induction motors have a finite primary or secondary length, which generates end-effects, whereas a conventional induction motor is arranged.
