Ward-Leonard Generator


Energy Source: Vibration
Application: Machinery
Specific Location: Feet of the induction motor
Data Duration: 03m 39s
Data Frequency: 2048 Hz

Abstract: The acceleration of a Ward-Leonard set was measured. This consists of a 3-phase induction motor that drives a dc generator via some flexible couplings. The set is bolted securely to a heavy table. Data Logger was positioned near the bottom of the machine, cable-tied and taped to one of the tapered supports (data logger is in an angle). The logger was on for approximately 3 minutes that included start-up and turn off. No picture was taken of the mounted data logger but picture shows the location. Features: a) Start-up between 11.38 - 16.8 seconds b) Turn-off start at 174.5 s
