GROUP 4 JULY 26‚ 2013 EE 4101 ENGR. KENNETH F. FAJILAN Reluctance Motor Introduction A reluctance motor is a type of electric motor that induces non-permanent magnetic poles on the ferromagnetic rotor. Torque is generated through the phenomenon of magnetic reluctance. There are various types of reluctance motor: Synchronous reluctance Synchronous reluctance motors have an equal number of stator and rotor poles. The projections on the rotor are arranged to introduce internal flux “barriers“

Wriston Manufacturing We identified seven factors contributing to the variance in overhead costs from plant to plant. However‚ in order to best understand how these factors contribute to inter-plant variance‚ it is helpful to first take note of the individual components of total overhead. As noted in the case‚ fixed overhead includes depreciation‚ utilities‚ salaries‚ and fringe benefit costs of employees‚ whereas variable costs consist of first-line supervisors’ wages‚ costs of set-up labor‚ scrap

AC Motors vs DC Motors DC Motors Prof. Dr. M. Zahurul Haq zahurul@me.buet.ac.bd http://teacher.buet.ac.bd/zahurul/ Department of Mechanical Engineering Bangladesh University of Engineering & Technology e316.eps ME 475: Mechatronics AC motors are smaller in size‚ reliable and less costly. AC motors run at fixed speed set by the line frequency. Easy speed‚ torque & direction controls in DC motors. DC motors are generally operate at lower voltages which makes these easier to interface with control

Morgan Motor Company (MMC) began as a family company and has remained that way over the years. Decisions were largely driven by steady demand for their luxury product. Traditionally‚ decision-making was premised on production quotas that kept supply slightly behind demand. While the company made a profit‚ it was not enough to sustain the company in the long term due increasing costs caused by inefficient methods of production. The key area for improvement was strategic planning based on detailed

ELECTRIC MOTOR CONTROLS Once the proper motor is selected‚ understanding the many various control devices available and their uses and limitations becomes an important part related to reliable operation and protection of the motor and the personnel using the motor. Motor Control Topics There are four major motor control topics or categories to consider. Each of these has several subcategories and sometimes the subcategories overlap to some extent. Certain pieces of motor control equipment can accomplish

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

Manufacturing Beauty Manufacturing Beauty Cindy Jackson in my opinion has major issues. She thinks beauty is on the outside and does whatever she can to make herself look like an imaginary person. It seems to me that she is doing all this to try to make money. Her website is all about selling cosmetics.
