# Question: What is the relationship between electrical and mechanical degrees?

Contents

Mechanical degrees in a motor refers to the rotation of the shaft. 1 revolution of the shaft equals 360 mechanical degrees. Electrical degrees in a motor has to do with the magnetic position of the rotor. One transition from “North” to “South” to “North” again equals 360 electrical degrees.

## What is electrical angle and mechanical angle?

The mechanical angle is angle of rotor shaft vs stator, whereas the electrical angle is the angle between poles (rotor vs stator). If you have one pole pair only, then electric angle= mechanical angle.

## What are electrical degrees?

1 : one 360th of a cycle of an alternating current. 2 : one 360th of the angle subtended at the axis of an alternating current by two consecutive field poles of like polarity.

## What electrical angle means?

[ə′lek·trə·kəl ′aŋ·gəl] (electricity) An angle that specifies a particular instant in an alternating-current cycle or expresses the phase difference between two alternating quantities; usually expressed in electrical degrees.

## What is difference between electrical degree and mechanical degree?

Mechanical degrees in a motor refers to the rotation of the shaft. 1 revolution of the shaft equals 360 mechanical degrees. Electrical degrees in a motor has to do with the magnetic position of the rotor. One transition from “North” to “South” to “North” again equals 360 electrical degrees.

## What is electrical speed and mechanical speed?

Electrical speed and mechanical speed are related as a function of the number of machine poles, p, or pole-pairs, p/2. If p=2, as in Fig. 1, then there is one magnetic rotation for every one mechanical rotation, i.e., the stator windings see one flux cycle as the rotor turns once.

## Is Electrical Engineering a good degree?

Like in any other Engineering field, Electrical Engineering graduates have the chance to secure high paying jobs. … Just keep in mind that both career opportunities and salaries will increase if you continue your education and pursue a graduate degree (Master’s) in Engineering.

## What is the degree of electrical engineering?

Bachelor’s Degree in Electrical Engineering: A Bachelor of Science (BS) or Bachelor of Engineering (BEng) in electrical, electronics or computer engineering generally leads to a job as an engineer, while a Bachelor of Science in Engineering Technology or a Bachelor of Engineering Technology leads to employment in …

## Are electrical engineers in high demand?

Overall, electrical engineers are in demand. According to the Bureau of Labor Statistics, electrical engineer jobs are projected to grow by 9% in the coming years. There is always a need for entry-level engineers as older ones leave the field.

## What is distribution factor?

The distribution factor is defined as the ratio of phasor sum of coil emf to the arithmetic sum of coil emf which is denoted as Kd. It is also known as belt factor or breadth factor. The formula for finding Distribution factor is, Note that, Distribution factor is always less than unity.

## What do you mean by synchronous motor?

A synchronous motor is one in which the rotor normally rotates at the same speed as the revolving field in the machine. … The principle of operation of a synchronous motor can be understood by considering the stator windings to be connected to a three-phase alternating-current supply.

## Why is it called a split phase motor?

The resultant of these two current is IT—the resultant of these two current produce rotating magnetic field which rotates in one direction. In a split-phase induction motor, the starting and main current get split from each other by some angle, so this motor got its name as a split-phase induction motor.

## Why are alternators rated in KVA and not in kw?

If we connect inductive or capasitive load (When power factor is not at least unity), The output would differ than as there are losses occurs due to low power factor. For this reason, KVA is an apparent power which does not take in to account the PF (Power factor) instead of KW (Real Power).

## What is d axis and q axis?

The d axis, also known as the direct axis, is the axis by which flux is produced by the field winding. The q axis, or the quadrature axis is the axis on which torque is produced. By convention, the quadrature axis always will lead the direct axis electrically by 90 deg.

## What is meant by synchronous condenser?

In electrical engineering, a synchronous condenser (sometimes called a syncon, synchronous capacitor or synchronous compensator) is a DC-excited synchronous motor, whose shaft is not connected to anything but spins freely.
