A line of permanent-magnet synchronous motors (PMSM) fulfill the soon-to-be-implemented IE4 (Super Premium Efficiency) classification. The motors are 40% more efficient than IE2 inverter- driven ...
The motor-speed-control circuit in the figure shows an SG3524 pulse-width-modulation (PWM) IC, U2, driving the high side of a motor through a p-channel FET, Q1. The motor terminal voltage is more ...
The energy-efficiency regulatory update scheduled for 2023 will affect builders of HVAC equipment, industrial fans, cooling towers and pumps, including those used in irrigation systems. The new ...
Why EV manufacturers are working toward eliminating rare-earth materials from their motors. An introduction to the wound-rotor synchronous motor (WRSM) architecture, and some of its innovative ...
Variable frequency drives (or VFDs) are widely used throughout industry to provide adjustable speed control of ac motors. Although modern versions are relatively simple to install and operate, VFDs ...
