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

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“

making presented in this chapter. Based on Schrage’s first scenario‚ the problem would be: “If the CRM will completed‚ what would happen to the current employees?” As such‚ that should be the focus of the CIO. There is still no guarantee that there would be mass layoff‚ but only a possibility. Therefore‚ the CIO needs to discuss with its employees the possible scenarios and identify what method of action should be taken for each of the scenarios. One possible scenario is that the mass layoff is inevitable

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

CHECKPOINT: MOTIVATING EMPLOYEES A manager can motivate an employee by using both intrinsic and extrinsic motivation‚ depending on the type of employment. Finding ways for the employees to actually enjoy their job is probably the best way to motivate. Typically‚ if an employee enjoys their job‚ they are more likely to perform their job more efficiently. If it’s a job that is hard to find ways to make more enjoyable‚ using extrinsic motivation such as a higher pay or rewards upon performance

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

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
