What is Siemens SIMOREG DC MASTER CONVERTER? And how does it work?

DC Converter is a kind of electric energy control device that transforms industrial frequency power into another frequency. One of the main functions of the Converter is speed regulation. So what is the Siemens DC MASTER CONVERTER and how does it work?

1. First of all, Siemens DC MASTER CONVERTER is a motor speed MASTER CONVERTER, including motor DC MASTER CONVERTER, pulse width DC MASTER CONVERTER, thyristor DC MASTER CONVERTER, etc. It is generally a modular DC motor MASTER CONVERTER. Power supply, control and drive circuit are integrated. It has the characteristics of small size and light weight. It can be used alone or directly installed on a DC motor to form an integrated DC speed regulating motor. It can have all the functions that a speed MASTER CONVERTER should have.

2. Working principle

A DC MASTER CONVERTER is a device that regulates the speed of a DC motor. The upper end is connected to the AC power source, and the lower end is connected to the DC motor. The DC MASTER CONVERTER converts the AC power into two output DC power sources, one is input to the DC motor excitation (stator), the other is input to the DC motor armature (rotor), and the DC MASTER CONVERTER Adjust the speed of the DC motor by controlling the armature DC voltage. At the same time, the DC motor gives a feedback current to the MASTER CONVERTER, and the MASTER CONVERTER judges the speed of the DC motor based on the feedback current, corrects the armature voltage output if necessary, and adjusts the speed of the motor once again.

The following occasions need to use a DC MASTER CONVERTER:

1. A wider range of speed regulation is required;

2. Need a faster dynamic response process;

3. The transition process that needs to be automatically smoothed during acceleration and deceleration;

4. Large torque when low-speed operation is required;

5. It needs better excavator characteristics, which can automatically limit the overload current to the set current.

The above five points are also the application characteristics of DC MASTER CONVERTERs.

Our company has focused on the sales of Siemens spare parts products and solution services for more than ten years. The products involve industrial automation, process automation, and power automation, especially the sales of products that are only used as spare parts, trade-in, scarce, non-standard, and customized special parts. In response to the needs of our customers, the company has a large amount of stock, especially the products that Siemens has announced to stop supplying.
