MKD041B-144-KG0-KN 同步电机是一种常用的交流电机，其工作原理与感应电机（即异步电机）相似。同步电机是电力系统的心脏，它是一种集旋转与静止、电磁变化与机械运动于一体，实现电能与机械能变换的元件。

同步电机的特点是稳态运行时，转子的转速和电网频率之间有不变的关系，即n=ns=60f/p，其中f为电网频率，p为电机的极对数，ns称为同步转速。若电网的频率不变，则稳态时同步电机的转速恒为常数而与负载的大小无关。

效率高：同步电机在运行时的效率较高，尤其是大型同步电机，其效率能够达到98%以上。

功率因数可控：同步电机可以调节其功率因数，通过调节励磁电流的大小，可以将功率因数调节到任意值，从而实现无功补偿或者有功滤波。

调速性能好：同步电机可以通过调节励磁电流的大小来改变电机的转速，从而实现调速控制。

运行稳定性好：同步电机具有稳定的运行特性，其转速与电网频率保持恒定的比例关系，不受负载变化的影响。

维护方便：同步电机结构简单，运行稳定，维护起来相对方便。

MKD041B-144-KG0-KN, manufactured by Rexroth, Indramat, Bosch, is a digital AC synchronous servo motor in the MKD series. The MKD041B-144-KG0-KN has a rotary motor feedback system and is driven by a straight shaft (with shaft seal). This servo motor has winding code 144 and no brakes.

MKD041B-144-KG0-KN synchronous motor is a commonly used AC motor, its working principle is similar to induction motor (that is, asynchronous motor). Synchronous motor is the heart of power system, it is a set of rotation and static, electromagnetic change and mechanical movement in one, to achieve electrical energy and mechanical energy conversion components.

Synchronous motor is characterized by steady state operation, there is a constant relationship between the rotor speed and the power grid frequency, that is, n=ns=60f/p, where f is the power grid frequency, p is the pole number of the motor, ns is called synchronous speed. If the frequency of the power grid is unchanged, the speed of the synchronous motor is constant in the steady state and has nothing to do with the size of the load.

MKD041B-144-KG0-KN synchronous motor can be divided into synchronous generator and synchronous motor. Running as a motor is an important operation mode of synchronous motor, which is more and more widely used in variable frequency speed control system. In addition, the synchronous motor can also be connected to the power grid as a synchronous compensator, without any mechanical load, by adjusting the excitation in the rotor to the power grid to emit the required inductive or capacitive reactive power, in order to improve the power factor of the power grid or adjust the voltage of the power grid.

MKD041B-144-KG0-KN synchronous motor advantages include:

High efficiency: The efficiency of synchronous motors is high during operation, especially large synchronous motors, whose efficiency can reach more than 98%.

Power factor controllable: synchronous motor can adjust its power factor, by adjusting the size of the excitation current, you can adjust the power factor to any value, so as to achieve reactive power compensation or active power filtering.

Good speed control performance: synchronous motor can change the speed of the motor by adjusting the size of the excitation current, so as to achieve speed control.

Good operating stability: the synchronous motor has stable operating characteristics, and its speed maintains a constant proportional relationship with the power grid frequency, and is not affected by load changes.

Easy maintenance: synchronous motor structure is simple, stable operation, relatively easy to maintain.
