What are the subjects to which the design of electrical machines is compared to *?

1. What are the subjects to which the design of electrical machines is compared to? 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.

What are the main factors affecting the design of electrical machine?

Major considerations in Electrical Machine Design

  • Magnetic circuit or the flux path:
  • Electric circuit or windings:
  • Insulation:
  • Cooling system or ventilation:
  • Machine parts:

What are the different methods of electrical machine design?

There are some general design methods, which can be applied in terms of different disciplines/domains: electromagnetic design, thermal design, structural design, multi-physics design, material design, and manufacturing process design.

What is electric machine design?

The basic design of an electrical machine involves the dimensioning of the magnetic circuit, electrical circuit, insulation system etc., and is carried out by applying analytical equations. A designer is generally confronted with a number of problems for which there may not be one. solution, but many solutions.

IMPORTANT:  Can any force do work without energy transfer?

Can electrical engineers design machines?

What Electrical Engineers Do. Electrical engineers design, develop, test and manage the manufacturing of electrical equipment, from electric motors and navigation systems to power generation equipment and the electrical components of vehicles and personal devices.

What are the main design parts of an electric machine?

The two main parts of an electrical machine can be described in either mechanical or electrical terms. In mechanical terms, the rotor is the rotating part, and the stator is the stationary part of an electrical machine.

What are the main dimensions in electrical machine design?

In rotating machine the active part is cylindrical in shape. The volume of the cylinder is given by the product of area of cross section and length. If D is the diameter and L is the length of cylinder, then the volume is given by πD2L/4. Therefore D and L are specified as main dimensions.

How many different approaches are present in the computer aided design?

Explanation: There are 4 types of different approaches present in the computer aided design. They are analysis method, synthesis method, hybrid method, optimisation method.

What are the different modes of heat dissipation in electrical machines?

The heated parts of an electrical machine dissipate heat into their surroundings by conduction, and convection assisted by radiation. This mode of dissipation of heat is important in the case of solid parts of machine like copper, iron and insulation.

IMPORTANT:  Why are researchers looking at alternative sources of energy?

Why are ferromagnetic materials used to design electrical machines?

Solely Ferro-magnetic materials have the magnetic properties that are well appropriate for electrical machines. Ferro-magnetic properties are cramped virtually entirely to Cobalt iron, and nickel and their alloys.

What are electrical engineering materials?

Electrical Engineering materials –i.e. Conductors, Semiconductors, Insulators, Magnetic materials etc. Civil Engineering materials – i.e. Cements, Iron, Stones, Sans etc.

How many types of machine are there?

There are six types of simple machines — the inclined plane, the wedge, the screw, the lever, the wheel and axle, and the pulley. These six have specific features and do unique jobs, even though some may work in similar ways.

What subjects are needed for electrical engineering?

To study an electrical engineering degree, you will need a strong background in mathematics and science subjects (especially physics). However, don’t be deterred; many courses will start with some foundation modules designed to ensure this background knowledge is up to the required standard.

What does an electrical design engineer do?

An electrical design engineer is a professional who develops electrical systems such as alarms and lighting. They use vast knowledge of the principles of physics and material sciences to help create solutions for new electrical systems and provide maintenance or installation services to current electrical systems.

What is the difference between an electrician and an electrical engineer?

Electric engineers design the power systems and the equipment that distribute energy, while electricians install wiring and make electrical repairs.
