Coaxial servo drive

Coaxial servo drive provides a coaxial servo drive, and including servo driving roller, the axle head of roller is provided with driving motor, and driving motor includes the stator, sets up the rotorblock in the stator, and rotor block and the concentric fixed connection of roller one end are provided with the encoder on the roller. The utility model discloses the structure is ingenious, and thedesign is novel, very big improvement the work efficiency of high -speed servo drive, stability and precision, simultaneously, compact structure, occupation space is little, drive torsion is big, thetransmission is stable, operating time is long, the maintenance period is long, power consumption is few, mechanical wear is little, long service life. 同轴伺服驱动装置，提供了种同轴的伺服驱动装置，包括伺服驱动辊筒，辊筒的轴端设置有驱动电机，驱动电机包括定子、设置在定子内的转子体，转子体与辊筒端同心固定连接，辊筒上设置有编码器。本实用新型结构巧妙，构思新颖，极大的提高了高速伺服驱动的工作效率、稳定性及精度，同时，结构紧凑，占用空间小，驱动扭力大，传动稳定，工作时间长，维护周期长，电能消耗少，机械磨损小，使用寿命长。
