To Proform the Block Rotar Test of 3 Phase Induction Motor

To Perform the Blocked Rotor Test of 3 Phase Induction Motor from Glass Agencies is a specialized laboratory setup developed for electrical engineering education, training, and experimental analysis of three phase induction motors. This system is used to conduct the blocked rotor test, which is essential for determining important motor parameters such as starting current, input power, copper losses, and equivalent circuit constants under locked rotor conditions. The setup consists of a three phase induction motor securely mounted on a rigid base frame, with a mechanical arrangement that safely locks the rotor to prevent rotation during testing. A controlled power supply is provided to apply reduced voltage to the stator windings, ensuring safe operation while allowing accurate measurement of electrical characteristics. The system is equipped with suitable measuring instruments including voltmeters, ammeters, and wattmeters that enable precise observation of voltage, current, and power input during the test. Clearly marked terminals, switches, and control components allow users to carry out the experiment in a systematic and safe manner, making it suitable for students and laboratory personnel. The arrangement supports gradual variation of applied voltage, allowing readings to be recorded accurately for analysis and calculation of motor parameters. The apparatus is assembled using high-quality electrical components, insulated wiring, and sturdy mechanical parts to ensure safety, consistent performance, and long service life in laboratory environments. Its compact and organized design allows easy placement on laboratory benches while providing sufficient access for operation and observation. The rigid construction minimizes vibration and ensures stability during testing, resulting in reliable and repeatable readings. This setup is ideal for use in engineering colleges, technical institutes, vocational training centers, and research laboratories where practical understanding of three phase induction motor testing is required. Each unit supplied by Glass Agencies undergoes thorough inspection and testing to verify electrical accuracy, mechanical stability, and overall operational reliability before dispatch. The system helps bridge theoretical concepts with hands-on experimentation, enabling learners to gain clear insight into motor behavior under blocked rotor conditions and strengthening their understanding of induction motor performance and equivalent circuit analysis in power engineering studies.
