What is the relation between electrical and mechanical angle of an electrical machine?

What is the relation between electrical and mechanical angle of an electrical machine?

There is relation between electrical and mechanical angle, Electrical angle =P\2 (mechanical angle).

What is difference between electrical 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 an 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.

What is the working principle of single phase induction motor?

Starting Principle A single phase induction motor consists of a single phase winding on the stator and a cage winding on the rotor. When a 1 phase supply is connected to the stator winding, a pulsating magnetic field is produced. In the pulsating field, the rotor does not rotate due to inertia.

What is the concept of electrical degree?

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.

How to calculate the electrical and mechanical angle of an induction motor?

1 In a two-pole motor (P = 2): Electrical Angle = Mechanical Angle 2 In a four-pole motor (P = 4): Electrical Angle = 2 times Mechanical Angle 3 In a six-pole motor (P = 6): Electrical Angle = 3 times Mechanical Angle

Is the load angle zero in a synchronous motor?

For ideal motor, the load angle is zero since the rotor poles aligned with stator poles, but in practice, this is not possible. The motor has both mechanical and electrical losses, hence load angle is always present in the synchronous motor.

How is the torque of a synchronous motor measured?

The Torque produced in the synchronous motor is purely depending on the load angle (sin δ). It is measured by the degree in electrical. Increasing in load angle indicate the decreasing magnetic locking between the rotor poles and stator poles. When δ = 90 deg.

What is the difference between mechanical and electrical angle?

The mechanical angle is angle of rotor shaft vs stator, meanwhile the electrical angle is the angle between poles (rotor vs stator).
