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:

- In a two-pole motor (P = 2): Electrical Angle = Mechanical Angle

- In a four-pole motor (P = 4): Electrical Angle = 2 times Mechanical Angle

- In a six-pole motor (P = 6): Electrical Angle = 3 times Mechanical Angle

etc.

Yes, it is the number of pole pair of the motor.

In the case of asynchronous machine, you must also take the slip in consideration.

For asynchronous machines, the electrical angle (thetaE) is related to the mechanical angle (thetaM) in terms of the number of poles (N) as follows:

thetaE = (N/2) * thetaM

Mechanical angle is half of 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:

- In a two-pole motor (P = 2): Electrical Angle = Mechanical Angle

- In a four-pole motor (P = 4): Electrical Angle = 2 times Mechanical Angle

- In a six-pole motor (P = 6): Electrical Angle = 3 times Mechanical Angle
