MR497E Electrical Machine System Trainer Electrical Training Equipment Teaching Equipment
VI.Product Overview
1.1 Overview
The MR497E electrical experiment training board is a multifunctional and comprehensive experimental device designed to provide students with a comprehensive experience in electrical and motor drag experiments. The device is not only suitable for completing motor drag experiments, but can also be used for single-phase and three-phase transformer experiments, and can even be expanded to electrical control technology experiments. Its design takes into account the needs of teaching and laboratory environments, and is equipped with necessary instruments, special power supplies, motors and other experimental devices and connection lines to ensure the smooth progress of experiments.
1.2 Features
Strong comprehensiveness: The design of the MR497E electrical experiment training board allows for a variety of electrical experiments, including motor dragging, single-phase and three-phase transformer experiments, and electrical control technology experiments, making it a versatile experimental platform.
Well-equipped: The device provides all the necessary components and connection lines, including instruments, dedicated power supplies and motors, etc., to ensure that users can conduct various experiments without obstacles.
High-quality materials: The motor rails are made of stainless steel, and the plate uses 20 mm thick steel plates. These high-quality materials ensure the durability of the equipment, reduce the noise during motor operation, and prevent deformation, ensuring that the equipment can operate stably for a long time.
Accurate measurement: The "corrected DC dynamometer" is used to measure the output power of the prime mover. This design overcomes the problems of large dead zone and large error encountered in the previous use of "eddy current dynamometers", and improves the accuracy of measurement.
Safety protection function: The equipment is equipped with single-chip voltage type, current type leakage protection and phase-to-phase, space overload or short circuit monitoring automatic protection function, which greatly improves the safety of the experiment.
