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

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

Design of Induction Motors Introduction: Induction motors are the ac motors which are employed as the prime movers in most of the industries. Such motors are widely used in industrial applications from small workshops to large industries. These motors are employed in applications such as centrifugal pumps‚ conveyers‚ compressors crushers‚ and drilling machines etc. Constructional Details: Similar to DC machines an induction motor consists of a stationary member called stator and a rotating

The speed of an asynchronous motor rotating field and thus its rotor speed depends on the number of pairs of poles in the stator field .the rotor speeds n are lower than the table values by the amount of the relevant slip speed ns. Motors are designed with up to three stators windings‚ which have different number of pairs of poles. They can therefore run at up to pairs of poles. They can be in any desired ratio to one another. A pole-changing switch is used to changing poles for the desires speed

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

and a motor in a circuit with two jumpers. 4. The theory was applied. The jumpers were connected to the alternate voltage supply. 5. The direction of DC motor was tested and determined. 6. All switches were in closed position at initial condition. 7. Only switch 1 and 4 was closed at the first condition as in figure 2(a). The direction of DC motor and the RPM of DC motor was recorded 8. Switch 1 was opened and switch 2 was closed as in figure 2(b) after the first reading was recorded. The motor was

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. Since
