46 Electric Motor Repairer Questions and Answers:

1 :: Explain me the abilities you have in order to work with us as electric motor?

I have the ability to make precisely coordinated movements of the fingers of one or both hands to grasp, manipulate, or assemble very small objects, quickly move your hand, your hand together with your arm, or your two hands to grasp, manipulate, or assemble objects, tell when something is wrong or is likely to go wrong. It does not involve solving the problem, only recognizing there is a problem, keep your hand and arm steady while moving your arm or while holding your arm and hand in one position, arrange things or actions in a certain order or pattern according to a specific rule or set of rules (e.g., patterns of numbers, letters, words, pictures, mathematical operations).

2 :: What is stepper motor. What is the use of stepper motor?

The motor which work or act on the applied input pulse in it, is called as stepper motor. This stepper motor is under the category of synchronous motor, which often does not fully depend of complete cycle. It likes to works in either direction related to steps. for this purpose it mainly used in automation parts.

3 :: Tell me why series motor cannot be started on no-load?

Series motor cannot be started without load because of high starting torque. Series motor are used in Trains, Crane etc.

4 :: Do you know what Is The Role Of A Commutator?

The function of commutator is to facilitate the collection of current from armature conductors. It converts the alternating current induce in the armature conductors into unidirectional current in the external load circuit.

5 :: Tell me what Is A Feedback In Control System?

The Feedback in Control System in one in which the output is sampled and proportional signal is fed back to the input for automatic correction of the error ( any change in desired output) for futher processing to get back the desired output.

6 :: Tell me when Will The Engine Fail Message Appear On The Pfd?

If actual thrust is less than commanded thrust during takeoff with airspeed between 65kts and V1-6kts. FCOM 1 70.20.16

7 :: Tell me the Methods For Starting An Induction Motor?

The different methods of starting an induction motor:

☛ DOL:direct online starter
☛ Star delta starter
☛ Auto transformer starter
☛ Resistance starter
☛ Series reactor starter

8 :: Tell us what are the skills required for electric motor employee in order to success in his work?

Repairing machines or systems using the needed tools, Determining causes of operating errors and deciding what to do about it, Conducting tests and inspections of products, services, or processes to evaluate quality or performance, Identifying complex problems and reviewing related information to develop and evaluate options and implement solutions, Using logic and reasoning to identify the strengths and weaknesses of alternative solutions, conclusions or approaches to problems.

9 :: Tell us why syn. generators are used for the production of electricity?

Synchronous machines have capability to work on different power factor (or say different imaginary power varying the field EMF. Hence syn. generators r used for the production of electricity.

10 :: Tell me what Is The Function Of Brushes?

The purpose of brushes is simply to lead current from the rotating loop or winding to the external stationary load.
