Different types of CC sources

It is important to note that the batteries are considered as the most common DC source. They produce electrical energy through the conversion of chemical energy, consisting of secondary cells, rechargeable cells, or primary cells, which can not be recharged. Generators are capable of converting mechanical energy into electrical energy. The generators, in case of being of direct current, are also called dynamos and, when they are of alternating current, of alternators.

Numerous DC sources can be found which are capable of providing voltages or currents, regardless of the characteristics of the load to which they are connected. Among the various sources, it is possible to emphasize the voltage of direct current, which has the possibility of being divided basically into three categories, they are the batteries, generators and power supplies. Power supplies are the most common of being found in laboratories, in which they use the processes of rectification, so that it is feasible to convert a voltage with variation in the time in a tension of fixed magnitude. Even in an ideal DC current source, even if there are variations in voltage, the source can always provide a fixed current to any electronic system. https://www.mrosupply.com/motors/ac-motors/explosion-proof-motors/699095_cl5001-i_baldor/

Direct Match Conjugate

The motors can start directly from the grid only if they are favorable to the conditions of the rated capacity of the grid being sufficiently high, making the motor starting current irrelevant and the motor starting current being of low value because of its very high power reduced. The starting of the motor is carried out without load, a factor that reduces the starting current time, emphasizing the effects on the power system.

In this way, it refers to the starting system, in which the electric motor VBM3538-5D receives at its terminals, a high voltage at the exact moment of departure. The cage rotor motor starts at full load and with the current rising by an average of four to eight times the rated current, varying according to the type and number of poles. The conjugate at the start must reach about 1.5 times the nominal torque.

It is considered as the simplified starting method, in which specific components are not used for the motor drive. Only contactors, circuit breakers or switch switches are used which allow the motor to be supplied with full voltage at the moment of starting.
