Ward-Leonard Generator
Energy Source: Vibration
Application: Machinery
Specific Location: Top of Induction Motor
Data Duration: 2m 34s
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 on top of the motor, cable-tied and taped to the connection box. The logger was on for approximately 3 minutes that included start-up and turn off.
Features:
- Start-up between 0.25 – 5.6 seconds
- Turn-off starts at 116.2 seconds

Ward-Leonard Generator
Energy Source: Vibration
Application: Machinery
Specific Location: Feet of the induction motor
Data Duration: 3m 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:
- Start-up between 11.38 – 16.8 seconds
- Turn-off start at 174.5 s

Ward-Leonard Generator
Energy Source: Vibration
Application: Machinery
Specific Location: On top of DC generator, close to coupling
Data Duration: 3m 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 on top of the DC generator, cable-tied to the metal case close to the coupling of the shafts. The logger was on for approximately 3 minutes that included start-up and turn off.
