Motor Retrofit For Precursor Stirring Reactor Reduces Energy Consumption By 35%
Motor Retrofit for Precursor Stirring Reactor Reduces Energy Consumption by 35%
Motor Retrofit for Precursor Stirring Reactor Reduces Energy Consumption by 35%
Project Overview
In the tungsten precursor workshop, a high-power induction motor paired with a gear reducer was previously used in a stirred reactor. The system suffered from frequent maintenance, oil leakage, and high energy consumption. By retrofitting the system with a permanent magnet direct drive motor (PMSM), these issues were resolved, and energy consumption was reduced by 35%.
