2 Pole Motors vs. 4 Pole Motors: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
2 Pole Motors have one pair of magnetic poles and run at higher speeds, while 4 Pole Motors have two pairs of poles and operate at lower speeds, offering higher torque.
Key Differences
2 Pole Motors generally operate at higher speeds due to fewer magnetic pole pairs. In contrast, 4 Pole Motors run at lower speeds but are more efficient at producing higher torque.
