Structural characteristics of rolling bearings imported from FAG

German FAG bearings (especially rolling bearings) are divided into two kinds of structure with cage and without cage. Among them, large-scale FAG bearings are generally required to withstand larger loads, often without a cage, but filled with rolling elements between the inner and outer raceways. And most of the small and medium rolling bearings are with cages.

Control mode of servo motor

Torque control: the torque control mode is to set the external output torque of the motor shaft through the input of external analog quantity or the assignment of direct address. For example, if 10V corresponds to 5nm, when the external analog quantity is set to 5V, the output of the motor shaft is 2.5nm: if the load of the motor shaft is lower than 2.5nm, the motor will rotate forward, and when the external load is equal to 2.5nm
