Details

Nidec and US Motors pool motors are a dependable option for restoring compatible pump systems to proper operation, and this 1.65 total horsepower model uses the NPTQ165 reference with a 13.6 amp draw and 48Y square-flange configuration. The Nidec US Motors motor line is especially helpful when exact flange style and proven brand reliability are both important in the replacement decision.

This motor has practical value because the 48Y square-flange frame is one of the most important physical details in a correct motor replacement. Matching THP, amperage, and flange design helps protect installation accuracy and support a more dependable repair outcome.

This type of motor is especially useful when the original pool motor has failed but the wet end remains serviceable and worth retaining. That makes motor-only replacement a smart way to restore performance without unnecessary broader equipment replacement.

Installed in the proper application, this Nidec US Motors pool motor helps support reliable performance, correct fitment, and stronger long-term service confidence.
