Motor and Transformer Training Device with Three-phase Four-wire Power Supply and Leakage Protection for Open-ended Experiments

The RM-F152 Motor and Transformer Training Device " is a novel comprehensive experimental device designed by our company. It can meet the experimental training requirements of courses such as "Motor Drive and Speed Regulation," "Basic Experiments of Motors and Drives," "Electrical Machines," and "Motors and Transformers . " It is particularly suitable for upgrading and transforming existing motor drive and control, AC/DC speed regulation training equipment in higher education institutions. It also provides ideal experimental equipment for secondary vocational schools and vocational colleges to quickly establish experimental courses when building or expanding laboratories.

This equipment is equipped with both voltage-type and current-type leakage protection devices to ensure operator safety. Each power output has monitoring and short-circuit protection functions, making it easy to use. All measuring instruments have protection functions. The entire system is meticulously designed, and with reliable component quality and manufacturing processes as a guarantee, the product performs excellently. All of these factors create conditions for open-ended experiments, which are conducive to improving students' ability to analyze and solve problems.
