In electric motors, the torque is also called torque, torque or torque and is the measure of the effort it takes to rotate an axis. Thus, the conjugate is the product of force and distance.

To size an electric motor you will need to calculate the torque requirements and speed of the load. Speed ​​is usually decided by the production rate required, by the process or determined by the customer.

Nowadays we need the efficient use of electric energy and for this we must watch over the design of the electric motors, which are responsible for much of the energy consumption in the industries.

The conjugate can be considered as the most complex, because each situation requires a different conjugate. The types of resistant conjugates can be:

– Linear resistant conjugate;

– Hyperbolic resistant conjugate;

– Constant resistant conjugate;

– Parabolic resistant conjugate;

– Indefinite resistant conjugate.

In order to establish the necessary conjugates, we need to make some calculations, and this will depend on the nature of the load and the motion used. Calculations will be made manually, and they can be used in any other situation.

The load resistant torque is the torque required to move the load as a function of speed. In it is included the useful torque and the torque conjugate, which will vary for each load, per tail of the friction losses of the load.
