Compared to AC motors DC motors have the following advantages:
1, there is no converter  does not turn under the whistle noise and high-speed 
 2 ,does not change the spark or fire rings and carbon brushes fault
3, is not large due to the change to the current situation of the motor burning
4 ,is not harmful to human beings and on the surrounding has a strong electrical interference for the electromagnetic radiation
5, dust resistance capability, better suited to the factory floor.
6,
 power can be more
7,
rotor diameter will be less bound by centrifugal force, speed can be higher

   
 AC motors do the vibration exciter aging equipment in the UK, France and other developed industrial countries have been dominant. Because in the vicinity of electrical power output of formant tremendous changes and, given the characteristics of AC motor, AC limitation control system development is difficult, our country has not developed a communication VSR equipment. Sigmar Sigmar After years of research R & D Center, from the development of VSR dedicated AC motor starting, while research resonance frequency AC motor characteristics of the laws and the corresponding control theory, has successfully developed the corresponding hardware and specialized software to solve the alternating current aging process of the vibration exciter Speed control accuracy in the problem. 

   
 As a high-tech, communication VSR VSR to Chinese users a more convenient, more durable, safer equipment selection.

   
AC Selection of Aging series control box in accordance with the required capabilities of the device reference Sigmar DC VSR equipment to carry out. Principles of AC and DC Aging exactly the same limitation, but not the same as electrical control principle, was not the same as motor control.

   
At present there is a communication Exciter Sigmar has matured, the parameters are as follows: 2.0kW, 9000r/min, 3.0kNf
