Understanding an electric motor begins with its most demanding moment: startup. The instant a motor starts, it experiences maximum mechanical and electrical stress. The EM2251 Locked-Rotor Add-on is a specialized tool designed to deconstruct this critical event. It provides a safe, controlled, and repeatable method for conducting locked-rotor tests, a fundamental procedure in electrical machine analysis. Created for students and educators in technical programs, this add-on integrates seamlessly with a main electrical machines trainer. It moves beyond theoretical concepts by allowing direct measurement of starting torque, inrush current, and power factor. The unit simplifies a complex industrial test into an accessible laboratory experiment, building a foundational understanding of motor performance from the ground up.
Using the EM2251, students develop essential hands-on skills in motor diagnostics and analysis. The curriculum focuses on the practical application of electrical theory. Learners will master the procedure for executing a locked-rotor test, a core competency for any electrical technician or engineer. They will gain experience in accurately measuring key startup parameters, including torque, current, and voltage. More importantly, they learn to interpret this data to understand a motor’s starting characteristics and how these relate to its overall design and application. This process reinforces the connection between theoretical motor models, like the equivalent circuit, and tangible, real-world performance metrics, preparing students for complex industrial challenges.

Aidex is proud to supply the EM2251 Locked-Rotor Add-on to learning institutions across the Midwest. We are committed to equipping educators and students in the region with the industry-leading tools they need to succeed. Our team ensures seamless integration of this technology into your curriculum.
The curriculum focuses on fundamental electrical machine principles. It covers locked-rotor test procedures, direct measurement of starting torque, analysis of inrush current, and calculating power factor under stall conditions. It also helps students relate these practical measurements to the theoretical equivalent circuit of an induction motor.
The target audience is post-secondary students in programs such as electrical engineering, mechatronics, industrial automation, and maintenance. It is an essential tool for instructors teaching courses on motor controls, power systems, and electrical machinery, providing a safe way to demonstrate complex concepts.
No, the EM2251 is a specialized add-on module. It is designed to work with a compatible Matrix Electrical Machines training system, which includes the main motor, dynamometer, and power supply unit. It cannot function on its own.
Safety is a primary design consideration. The unit includes a robust, transparent protective cover to prevent accidental contact with moving parts. It is designed for low-voltage operation and integrates with the main training system’s emergency stop functions to ensure a safe learning environment.
Yes, the EM2251 includes a comprehensive instructional manual. This manual contains essential background theory, detailed step-by-step guides for conducting experiments, and expected results to help guide students through the learning process.
