Why the starting torque of a dc series motor is high?
load is heavier so starting torque is requiredAnswerBecause the same current is passing through both the armature and field windings, the torque is proportional to the squareof the current. Since the starting current is alway high (no back emf), the torque will be very high indeed.
What is the duration of Torque film?
The duration of Torque - film - is 1.4 hours.
When was Torque - film - created?
Torque - film - was created on 2004-01-16.
What is the name of the first song in the movie torque?

What is the name of bike at end of movie 'Torque'?
It's Y2K Turbine Superbike
Would a DC motor turn if only the armature were supplied DC voltage?
if there are magnets on the stator and the commutator is phased properly this is known as a permanent magnet dc motor the starting torque is dependent on armature current and the strength of the magnet the speed is directly proportional to the armature voltage a shunt motor needs the field energized for starting. more field more starting torque
What is a torque transducer?
A transducer is an electronic device that measures something -- voltage, temperature or in this case torque. Torque is the force applied to twist something, like the twisting one does to tighten a screw, bolt or jar lid. So, a torque transducer is an electronic device that measures the amount of torque being applied to something.
What is the relation between torque and speed?
Torque is a force times a distance (the distance from the rotation axis where the force is applied). The angle at which the force is applied can also play a role. It is not directly related to speed.Torque is a force times a distance (the distance from the rotation axis where the force is applied). The angle at which the force is applied can also play a role.

What is the purpose of the energy?
Energy meter works on the same principle as the induction motor. An aluminium disc is placed inside a magnetic core with two limbs. One carries a voltage coil so its flux is proportional to voltage, the second carries a current coil so its flux is proportional to current. The two fluxes induce eddy currents into the disc, each of which interacts with the flux of the other to produce a torque, which accelerates the disc. This torque of course is proportional to flux × the eddy current, which equates to V × I, or power. A permanent magnet creates another eddy current resulting in a torque proportional to speed that brakes the disc, the combined result of these actions is that the speed of the disc is proportional to power, and the total number of revolutions is proportional to the energy that has passed through the meter. The disc drives a chain of gears that turn a mechanical counter, called a 'register'.
What is the relationship between torque and speed for an electric motor?
Torque and speed are inversely proportional
What is base speed?
The base speed of a DC motor is the speed at which it operates while delivering rated torque with rated armature voltage and field current applied.
What force is applied to a lever?
torque
Why do moving coil dynamometer type instruments have quadratic scale?
bcs the torque developed in dynamometer instrument is directly proportional to the square of the current passes so thts why its scale is quadratic in nature
Is torque and current proportional?
Sometimes, for example in a separately excited dc motor. But in a series-wound dc motor the torque is proportional to current-squared, which gives the motor a very high starting torque and this makes series motors very popular for traction.
