Details

Nidec and US Motors pool motors are dependable replacement options for preserving the performance and fit of compatible pump systems, and this 1.0 HP version uses the ASB841 reference with a 14.4 amp draw and 56Y square-flange configuration. The Nidec US Motors line is especially useful when buyers want a recognizable, service-proven motor platform instead of an uncertain substitute.

This motor has practical value because the 56Y square-flange layout is one of the most important physical details in a correct pool motor replacement. Matching horsepower, amperage, and flange style helps preserve the existing pump arrangement and supports a cleaner installation process.

This type of motor is especially useful when the original pool motor has failed while the rest of the pump remains structurally sound and worth keeping in service. That helps make replacement more efficient and more cost-effective.

Installed in the proper application, this Nidec US Motors pool motor helps support dependable operation, accurate fit, and stronger long-term serviceability.
