Introduction to Paper Presentation on Siemens Dc Drives:

The paper is about DC drivers, which are used for controlling the variable speed, also works for low speed operations.

The variable speed drive is used for controlling the energy flow for mains to the process. And electric drive systems consist of the parts which includes an electrical actuator: which is used as controller, A driving electrical machine: which is used as motor, A driven machine: which is used as compressor.

The DC motors has the following parts: the frame, bearings, cummutator, brush assembly, armature, shaft. The DC motor rotates due to the interaction of magnetic fields like Permanent magnet and Armature magnetic field.

DC drivers are capable of controlling the variable speed; this is done by controlling the energy flow from the mains to that of the process. It includes the usage of various power components in order for controlling the drive operation. It requires various hardware and software components for controlling speed.

The SIMOREG 6RA70 includes two packages Power Module and Base Drive Panel. The power module includes the control electronics and power components which are used for controlling the drive operation. The Base Drive Panel, it contains the hardware and software which is needed of operating the speed of control modes.

The AC to DC conversion includes SCR which includes a control element called gate. This gate will behave as “turn-on” switch, for allowing full voltage. The voltage is passed until the device reverses which results in “turn off” automatically.

The paper is about DC drivers, which are used for controlling the variable speed, also works for low speed operations.
