AC Repulsion Motor
Model No. HV-EXP2262
With the availability of 3 phase power becoming common, the use of 3 phase AC squirrel cage motor became very common & demand increased for motors with single phase power, as the current in single phase is aconcern, hence motors up to 3Hp have been made in single phase power with the same induction design principle. The issue of starting of the motor with single phase was tackled by providing capacitor for creating phase difference. The simplicity in operation & immediate torque made it acommon motor for single phase power. This Model is the industrial/educational model suitable for demonstrating to students the complete know of the basics, components, starting methods, wear & tear & maintenance of these motors packaged in small rating. Students can make connections of their own with the help of the terminations provided for study of features viz starting methods, speed-torque, effect of phase angle, study of cogging/crawling, effect of reduced voltage, blocked rotor test. Technical Specs : Power ratings available :350W /750W /1KW /1.5KW Voltage Input: 230V AC 50hz RPM: 1440 /2880 RPM Single /Double shaft extension, List of Experiments Starting by DOL Starter Starting by reduced voltage starter. Load test & No load test of machine Speed-Torque Analysis Voltage-Speed Analysis Speed reversal Efficiency Analysis Blocked rotor test Cold Resistance & Hot Resistance Motor Operation parameters Basic Overhauling Know how.
