Calculating Wattage Rating for Generator to Power Electric Motor

AI Thread Summary
To power an electric motor with a voltage of 72-144VDC and a continuous current of 190A, the maximum electrical output is calculated to be 27.36 kW. Considering an efficiency of 85%, the required input power for the generator would be approximately 32.2 kW. This input power aligns closely with the motor's continuous rating of 43.7 HP. Therefore, a generator rated around 32.2 kW would be suitable for this application. Proper calculations ensure compatibility between the generator and motor specifications.

What would be the wattage ratting for a gas/diesel generator to power an electric motor with these specs.

72-144VDC
190A Continuous
43.7HP Continuous

Thanks

Well the maximum electrical output is : 144 x 190 = 27.36 kW

Assumming 85% efficiency the required input power would be 27.36/0.85 = 32.2 kW

Which (no surprise) is approximately equal to 43.7 HP as given.
 
thank you
 
Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
