Chapter 32, Problem 1SQ

To determine

Mention the mechanical degrees at which the two-pole motor travels for 360 electrical degree.

Answer to Problem 1SQ

The motor travels at 360 mechanical degrees.

Explanation of Solution

Given data:

The electrical degree is ${\theta }_e=360°$.

The number of poles in the system P is 2.

Formula used:

Write the general relationship between mechanical and electrical degree.

${\theta }_m={\theta }_e\left(\frac{\text{2}}{\text{P}}\right)$ (1)

Here,

P is the number of poles,

${\theta }_m$ is the mechanical degree, and

${\theta }_e$ is the electrical degree.

Substitute 2 for P and $360°$ for ${\theta }_e$ in Equation (1) to find the mechanical degree ${\theta }_m$.

$\begin{array}{l}{\theta }_m=360°\left(\frac{2}{2}\right)\\ {\theta }_m=360°\end{array}$

Conclusion:

Thus, the motor travels at 360 mechanical degrees.
