Or stop operating, or rotate backward.
The beneficial effects of the utility model are:
This utility model, under servomotor drives, moves left and right carbon brush component (carbon brush) and realizes it and contact with collector ring
Or depart from, dynamically regulate the carbon brush quantity contacted with collector ring sometime, thus realize temperature, the electric current density of brush are entered
Row regulation.
This utility model controls under device controls at PLC, the electric current of the brush arrived by measurement or the temperature of carbon brush, from
Dynamic adjust the carbon brush quantity contacting (compact siro spinning technology) with collector ring, realize it connect with collector ring by moving left and right carbon brush component
Touch or depart from, it is achieved the temperature of brush is adjusted；Can effectively prevent carbon brush overheated (carbon brush and collector ring may be burnt),
Get rid of potential safety hazard；The electric current density of brush can also be automatically adjusted, make the more safe and stable operation of unit.
When the exciting current of brush mount component reduces setting value (such as 90A) or carbon brush temperature less than setting value (such as 45 DEG C)
When, PLC controls device and automatically transfers signals to servomotor, and carbon brush is locked by carbon brush locking device simultaneously
Fixed, PLC controls device and controls servomotor work, and servomotor drive transmission is moved axially away from the direction of collector ring, carbon brush
Just not contacting with collector ring, electric current just can increase or temperature increases；If it is required, other one or more lifts brush dress automatically
Put the work above repetition, the reply speed of electric current and temperature can be accelerated.
When the exciting current of brush mount component often increases setting value (such as 90A) or temperature higher than setting value (such as 95 DEG C),
PLC controls device and automatically transfers signals to servomotor, and carbon brush is unclamped by carbon brush locking device simultaneously, and PLC controls device control
Servomotor processed works, and transmission is moved axially adjacent to the direction of collector ring, and carbon brush contacts with collector ring, electric current with regard to can reduce or
Temperature reduces, so that electric current and temperature can be returned to respective range of set value.If it is required, other one or more from
Dynamic brush lifting device repeats work above, can accelerate the reply speed of electric current and temperature.
