General Purpose vs. Inverter-Duty Motor Selection Guide

This document provides guidelines for selecting between a general purpose motor and an inverter-duty motor, particularly when used with variable frequency drives (VFDs). It explains the risks of overheating and voltage spikes for general purpose motors under VFD control, and details the performance and cost trade-offs of inverter-duty motors, including specific speed ratios and cable distance limits for IronHorse motors.
