What is the meaning of electrical angle?

[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.

Is the degree of cycle of EMF induced in the conductor of a machine?

Thus one complete revolution of conductor results in one complete cycle of induced emf. In other words, we can say that 360° mechanical rotation of conductor results in 360° change in the induced emf for two pole machine. Here when the conductor is at a, the induced emf is zero as magnetic field at a is zero.

How many electrical degrees are there in one alternation?

In describing alternating voltages and currents, the time for one complete cycle is considered to be equivalent to 360 electrical degrees (360°) or 2&pgr electrical radians.

What is the relation between electrical degree and mechanical degree Mcq?

Explanation: We know θelec = P/2θmech ⇒ d/dt(θelec) = P/2d/dt(θmech) ⇒ ω = P/2ωm. Explanation: Pole pitch is always expressed in electrical degrees, rather than in mechanical degrees.

What is electrical mechanical degree?

Mechanical and electrical engineering encompasses the manufacture and repairing of a diverse range of electrical and electronic products, such as engines, electrical products, consumer electronics, computers, mobile phones and others.

What is the speed of dc motor?

DC controls adjust speed by varying the voltage sent to the motor (this differs from AC motor controls which adjust the line frequency to the motor). Typical no load or synchronous speeds for an AC fractional horsepower motor are 1800 or 3600 rpm, and 1000-5000 rpm for DC fractional hp motors.

How do you calculate electrical degrees?

That means that 360 electrical degrees will occur when the shaft has rotated only 120 (3603) mechanical degrees. You can see that each time we divide the mechanical degrees by the number of pole pairs (or, the number of poles divided by 2). So in general we can say that θe=P2θm.

At what number of pole mechanical and electrical degree are equal?

If the pole pair of the machines is 1, then electrical and mechanical angle are equal.

Why pole pitch is expressed in electrical degrees not in mechanical degrees?

Explanation: Pole pitch is always expressed in electrical degrees, rather than in mechanical degrees. pole pitch = 180 electrical degrees or π electrical radians. Explanation: The EMF is generated in the active lengths only, and these active lengths are called the coil-sides of a coil.

What type of engineer is Tony Stark?

At the age of 14 he developed transistor , so he is electronic engineer . His suit contain a lot of mechanical parts and robotics so he is Mechanical engineer.

Can I do both electrical and mechanical engineering?

No it is not possible to get degree in Both simultaneously, However some college [provide a Minor degree along with major degree so you can choose minor course in your college and then you will both the degree but minor in one, among top institutes IIT follow such pattern.

What is the relationship between mechanical angle and electrical angle?

In a multipolar electrical machine (motor or generator), relationship between the mechanical angle and electrical angle is given by: Electrical angle = (P/2) x Mechanical angle where: P = Number of poles. So:

What is the difference between mechanical degree and electrical degree?

Mechanical degree is the unit for accounting the angle between two points based on their mechanical or physical placement. Electrical degree is used to account the angle between two points in rotating electrical machines. Since all electrical machines operate with the help of magnetic fields,…

What is an electelectrical angle?

Electrical angle is an angle that specifies a particular instant in an alternating-current/voltage cycle.

How do you find the electrical angle of a motor?

Electrical angle =P2 (mechanical angle). The mechanical angle is angle of rotor shaft vs stator, while the electrical angle is the angle between poles (rotor vs stator). If you have one pole pair only, then electric = mechanical.
