Complete kit for studying the 1.5kW DC motor

Included : DC motor , DC variable supply , Wattmeter , Magnetoelectric voltmeter , 20A magnetoelectric Ammeter , Power supply master/slave , Multimeter , Rheostat ,…

Manufacturer : Langlois - Model: PACK-DC1

• Study of connection schematics with shunt excitation and separate excitation.
 - Understanding and undertaking motor wiring depending on the selected excitation type.
 - Measurements and comparisons of the various consumed power, voltage and current values depending on the selected excitation type. 

• Calculation method used for determining the resistance value: 
- of the start-up rheostat 
- of the excitation rheostat 

• Study of the motor’s operation when unloaded, when loaded and when overloaded with separate excitation and with shunt excitation:
- Theoretical reminders of the mathematical formulae applying to a DC motor. 
- Understanding and undertaking motor wiring with measuring devices. 
- Creation of a table containing calculations and measurements of electrical and mechanical quantities at various points of the motor load: 

Current consumption of field system/in the rotor 
Power consumption of field system/in the rotor 
Rotation speed 
Useful power 
Motor torque 
Counter-electromotive force 
Rotor Joule decrease 
Efficiency

• Plotting of properties based on motor measurements: Rotation speed, efficiency, torque and power consumption as a function of the rotor current 
• Analysis of results and conclusion
