<![CDATA[Three-phase induction motors are the primary drive components in various modern industrial systems demanding high energy efficiency and operational reliability. However, conventional speed control methods have proven to waste electrical power and are less adaptive to dynamic load changes. Therefore, this study aims to design and fabricate an integrated speed control panel for a 3-phase AC induction motor utilizing a Chint NVF5-3.7/TS4-B Variable Speed Drive (VSD). In contrast to qualitative approaches, this research applies an applied quantitative methodology based on engineering design, validated through a literature review and empirical observations at PT. Tiga Kreasi Indonesia, Tangerang Regency. The panel prototype was precisely fabricated with dimensions of $800 \times 550 \times 300$ mm, using 2 mm thick steel plates coated with RAL 7035 paint, and complies with the IP42 protection standard. Its electrical architecture is integrated into four main subsystems: incoming, inverter, outgoing, and manual control system. Operational testing results validate that the VSD effectively regulates rotor rotation linearly against its output frequency, yielding measured speeds of 1,713 rpm at 35 Hz and 2,709 rpm at 50 Hz. Although the empirical evaluation revealed an escalation in slip value during low-frequency operations due to flux weakening, comprehensively, the implementation of this VSD control panel is proven reliable in regulating speed and possesses a highly significant potential for reducing power consumption compared to conventional Direct on Line (DOL) operations.]]>
