The torque motor works the same way a synchronous motor works. Magnets are attached on the inner surface of a drum, and a strator is present consisting of magnetic coils that are integrated via an iron matrix. These coils provide three-phase current and are star-switched.
It is a special type of synchronous motor.It works on the principle of hysteresis and the torque is produced due to hysteresis
Gross Torque
The pullout torque is the maximum torque a motor can achieve. Also known as breakdown or peak torque. It occurs at the point where, the increase in the rotor current is exactly balanced by the decrease in the rotor power factor.
A shunt-wound DC motor can maintain its speed well when the load torque varies.
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.

In SI, torque is measured in newton metres (N.m). The percentage torque varies according to the design and specifications of a motor.
Max torque and breakdown toarque are the same...,.the point at which a motor will stop/stall.
torque of synchronous motor with out feild exitation
The torque which is produced during the starting of motor is simply called as starting torque.
how to calculate hydraulic motor torque
flux linkage decreases due to that torque decreases and so speed will decreases
