ELAU MC-41110400伺服驱动器主要有伺服控制单元、功率驱动单元、通讯接口单元组成。 其中伺服控制单元包括位置控制器、速度控制器、转矩和电流控制器等。 伺服驱动器大体可以划分为功能比较独立的功率板和控制板两个模块。 功率板是强电部分，其中包括两个单元，一是功率驱动单元IPM用于电机的驱动，二是开关电源单元为整个系统提供数字和模拟电源。ELAU MC-41110400内部的转子是永磁铁，驱动器控制的U/V/W三相电形成电磁场，转子在此磁场的作用下转动。

The ELAU MC-41110400 servo driver mainly consists of servo control unit, power drive unit, and communication interface unit. The servo control unit includes position controller, speed controller, torque and current controller, etc. The servo driver can generally be divided into two modules: a power board and a control board, which are functionally independent. The power board is a strong current part, which includes two units. One is the power drive unit IPM used for motor drive, and the other is the switching power supply unit that provides digital and analog power for the entire system. The internal rotor of ELAU MC-41110400 is a permanent magnet, and the U/V/W three-phase electricity controlled by the driver forms an electromagnetic field. The rotor rotates under the action of this magnetic field.

The ELAU MC-41110400 servo controller module also provides feedback signals from the motor’s built-in encoder to the driver. The driver compares the feedback value with the target value and adjusts the angle of rotor rotation. When there is no control voltage in the ELAU MC-41110400 servo controller module, there is only pulsating magnetic field generated by the excitation winding in the stator, and the rotor remains stationary. When there is a control voltage, a rotating magnetic field is generated in the stator, and the rotor rotates in the direction of the rotating magnetic field. Under constant load, the speed of the motor changes with the magnitude of the control voltage. When the phase of the control voltage is opposite, the servo motor will reverse.
