What are the subjects to which the design of electrical machines is compared to?
Answer: d Explanation: The design of electrical machines is basically compared to as a science. It is also compared to as an art because of the designing
Answer: d
See lessExplanation: The design of electrical machines is basically compared to as a science. It
is also compared to as an art because of the designing
What is the relationship between power factor, current and conductor sizes?
Answer: c Explanation: The power factor is one of the limitations in the design of the machine. The poor power factor leads to high amount of current and in turn large conductor sizes have to be used.
Answer: c
See lessExplanation: The power factor is one of the limitations in the design of the machine. The poor power factor leads to high amount of current and in turn large conductor sizes have to be used.
The mechanical parts design is very much important in which type of machines?
Answer: b Explanation: The design of mechanical parts is very important in the high speed machines. It is so important because to reduce the mechanical stresses which occurs more in high speed machines.
Answer: b
See lessExplanation: The design of mechanical parts is very important in the high speed
machines. It is so important because to reduce the mechanical stresses which occurs
more in high speed machines.
What is the relationship between efficiency and the operating costs?
Answer: c Explanation: Efficiency is one of the limitations in the design of the machines. The efficiency should be as high as possible to reduce the initial cost.
Answer: c
See lessExplanation: Efficiency is one of the limitations in the design of the machines. The
efficiency should be as high as possible to reduce the initial cost.
How many types of stresses are present in the machine?
Answer: b Explanation: There are basically 3 stresses available in the machine. They are electrical stress, mechanical stress and thermal stress.
Answer: b
See lessExplanation: There are basically 3 stresses available in the machine. They are electrical stress, mechanical stress and thermal stress.
What happens if the insulating material is operated beyond the maximum allowable temperature?
Answer: d Explanation: The temperature rise is one of the limitations present in the design of machines. The insulating material when operated beyond the maximum temperature leads to the lifetime being drastically reduced.
Answer: d
See lessExplanation: The temperature rise is one of the limitations present in the design of
machines. The insulating material when operated beyond the maximum temperature
leads to the lifetime being drastically reduced.
How does the saturation levels limit the design?
Answer: d Explanation: The maximum allowable flux density to be used is determined by the saturation levels of ferromagnetic materials. The saturation levels provides high flux density which results in high cost.
Answer: d
See lessExplanation: The maximum allowable flux density to be used is determined by the
saturation levels of ferromagnetic materials. The saturation levels provides high flux
density which results in high cost.
How many limitations are present in the design of the machine?
Answer: c Explanation: There are basically 9 limitations in the design of the machines. They are saturation, temperature rise, insulation, efficiency, mechanical parts, commutation, power factor, consumer specification, standard specification.
Answer: c
See lessExplanation: There are basically 9 limitations in the design of the machines. They are
saturation, temperature rise, insulation, efficiency, mechanical parts, commutation,
power factor, consumer specification, standard specification.
How many parts are used in the design of the machines?
Answer: d Explanation: There are 5 parts involved in the design of the machine. They are magneticcircuit, electric circuit, dielectric circuit, thermal circuit, mechanical parts.
Answer: d
