The Torque Speed characteristics of a series connected dc motor is such that at zero load the speed is "infinite"! ie it over runs and can burn out/explode! The characteristics are quite easy to derive from the basic equations of a dc motor but you can see them in most text books on electrical machines.
What else can I help you with?
Why is motor current draw lower at full speed?
Because full speed is unloaded. As you load the motor, speed decreases, and slip increases, with an accompanying increase in current.
Why it is dangerous to supply power to an unloaded series connected DC motor?
Starting torque becomes very high due to which motor can attain very high speed and can damage its body and connected equipments.
What is the output when a secondary voltage of 24V is connected to bridge rectifier when no load is connected?
24VACRMS * 1.414 = 33.94VACPEAK The unloaded filtered DC voltage is 33.94V The unloaded unfiltered voltage will be a single polllarity AC voltage with a peak of 33.94V
What will be the unloaded voltage if the primary is connected to 500V on a transformer that has 200 turns on the primary and 100 turns on the secondary?
If that is 500VDC, the secondary will have 0VDC. if that is 500VAC, the secondary will have 250VAC.

What danger exists for the motor when the field of a lightly loaded motor is opened?
It can overspeed.
Why turbocharger overspeed?
Overspeed is usually the result of too small of a turbine housing/wheel used.
Why will unloaded series-wound motor over-speed?
yes and very quickly too. maybe 2 seconds
Why is motor current draw lower at full speed?
Because full speed is unloaded. As you load the motor, speed decreases, and slip increases, with an accompanying increase in current.
What is the Idaho definition of a unloaded firearm?
"Unloaded" as in it does not have any ammunition. It is unloaded.

What stops faster a loaded or unloaded vehicle?
Obviously an unloaded vehicle.
How many miles to the gallon does a 2008 Ford Transit van get?
depending on how hard you drive loaded or unloaded motor way or town mine a 140hp averages at 350/400 mile to a tank of fuel which cost £100 or 26p a mile ish but I run unloaded most of the time
