ST. LOUIS –June 30, 2019 – To respond to the growing demand for variable speed motors used to drive vertical pumps in municipal and industrial applications, Nidec Motor Corporation now stocks a line of totally enclosed fan cooled CORRO-DUTY® Vertical HOLLOSHAFT® Inverter Duty Motors. 

These U.S. MOTORS® brand motors are cast iron, and designed with full Class H insulating materials to withstand the steep-wave-front voltage impressed by the VFD waveform. They are designed to run smoother and cooler on inverter power supplies, which can lead to improved system efficiency and reliability.

In the past, this product offering was built-to-order, but can now be purchased off-the-shelf.

The motors are NEMA Premium® Efficient, and are available in 5-300 HP, with 2 & 4 Poles (3600 & 1800 RPM), and with frame sizes 184-449.
