Pole Arc Solution

STEP 0: Pre-Calculation Summary

Formula Used

Pole Arc = Number of Damper Bar*0.8*Slot Pitch
θ = n_d*0.8*Y_s
This formula uses 3 Variables

Variables Used

Pole Arc - (Measured in Meter) - Pole Arc is the distance measured on the circumference of the armature from the center of one pole to the center of the next pole.
Number of Damper Bar - Number of Damper Bar provides starting torque necessary for starting the synchronous motor. It also prevents hunting of synchronous motor.
Slot Pitch - (Measured in Meter) - Slot pitch is the distance between two adjacent slots. In dc machines, the slot pitch usually lies between 25 to 35 mm.

STEP 1: Convert Input(s) to Base Unit

Number of Damper Bar: 10 --> No Conversion Required
Slot Pitch: 32.2 Meter --> 32.2 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

θ = n_d*0.8*Y_s --> 10*0.8*32.2

Evaluating ... ...

θ = 257.6

STEP 3: Convert Result to Output's Unit

257.6 Meter --> No Conversion Required

FINAL ANSWER

257.6 Meter <-- Pole Arc

What is pole pitch?

The distance measured on the circumference of the armature from the center of one pole to the center of the next pole : 180 electrical degrees compare coil, pitch sense.

What is full pitch?

A full pitch is a ball that the batsmen can reach before it hits the ground. A long hop is a ball short of good length.

How to Calculate Pole Arc?

Pole Arc calculator uses Pole Arc = Number of Damper Bar*0.8*Slot Pitch to calculate the Pole Arc, Pole Arc is the distance measured on the circumference of the armature from the center of one pole to the center of the next pole. The pole arc refers to the angular span or extent of a magnetic pole in an electrical machine. It represents the angle covered by the magnetic field produced by a single pole in the machine. Pole Arc is denoted by θ symbol.

How to calculate Pole Arc using this online calculator? To use this online calculator for Pole Arc, enter Number of Damper Bar (n_d) & Slot Pitch (Y_s) and hit the calculate button. Here is how the Pole Arc calculation can be explained with given input values -> 257.6 = 10*0.8*32.2.
