today, you will learn about drives. specifically what they are and when do we use them with automations and PLCs.
During starting, electric motor often requires huge amount of electricity during start up for example changing the inertia of the
electric motor rotor or the connecting load on the shaft before it reach its monomial speeds..
an electric drives can be used to limit the in run current or the torque of the electric motor which result in a
a smooth and gradual startup, electrical drive prevent motor from damage and at the same extend the motor life span.
this method usually prevent the motor from heating up during start and stop operation.
by reducing mechanical stress on the motors shafts and the electro dynamic stress on the connecting cables.
it also reduces the operational cost of the system.
