VT130G2U4750交流电机驱动器是一种变频器，用于采用专门开发的控制方法（如可变频率驱动（VFD）或磁场定向控制(FOC)）来控制电机（通常是三相交流感应或三相BLDC电机）速度和扭矩。

VT130G2U4750变频驱动器(VFD)由三个主要元件组成:交流电机(通常为三相感应电机)、驱动控制器和用户界面。交流电机交流感应电机通常具有固定的速度，因此控制器相对简单。它将三相电压按顺序提供给电机定子的线圈，产生旋转磁场。这就感应出一个电场来驱动转子。交流传动控制器典型的工业交流传动控制器有三个半桥，每个半桥向定子提供正弦波电压。对于可调频率，在控制器中使用标量算法来改变电压，以确定相的频率，或伏特/赫兹。高端电机越来越多地使用更复杂的算法。

VT130G2U4750例如用于控制多相频率的矢量控制或磁场定向控制(FOC)。增加变速驱动器增加了控制算法的复杂性。这些驱动器还需要控制器提供软启动功能，以减少启动期间电机的负载和电流浪涌。这对于减少电机上的应力和为工厂车间的工业驱动提供最大的寿命是至关重要的。这是因为电机的浪涌电流可能是工作电流的七到十倍，启动时所需的扭矩可能是运行时的三倍。

VT130G2U4750数字软启动器控制器在启动过程中持续监控电压，根据电机负载进行调整，以提供平稳的加速、速度和扭矩控制。这用于启动和停止交流电机驱动系统，减少驱动器上的压力。这也减轻了电源的负载，降低了能耗，从而显著节约了成本。交流传动接口交流传动接口可以通过多种不同的连接方式实现。这些可以是4至20 mA电流环路、0至10 VDC电压信号或通过以太网或无线通信链路的远程连接。

VT130G2U4750 AC motor driver is a frequency converter, which is used to control the speed and torque of motor (usually three-phase AC induction or three-phase BLDC motor) by adopting specially developed control methods, such as variable frequency drive (VFD) or field oriented control (FOC).

VT130G2U4750 Variable Frequency Drive (VFD) consists of three main components: AC motor (usually three-phase induction motor), drive controller and user interface. Motor AC induction motor usually has a fixed speed, so the controller is relatively simple. It supplies three-phase voltages to the coils of the motor stator in sequence, and generates a rotating magnetic field. This induces an electric field to drive the rotor. AC drive controller A typical industrial AC drive controller has three half-bridges, and each half-bridge provides sine wave voltage to the stator. For adjustable frequency, a scalar algorithm is used in the controller to change the voltage to determine the frequency of the phase, or volts/hertz. More and more sophisticated algorithms are used in high-end motors.

The VT130G2U4750 is used, for example, for vector control or field orientation control (FOC) to control polyphase frequency. Adding variable speed drives increases the complexity of the control algorithm. These drivers also require the controller to provide soft start function to reduce the load and current surge of the motor during startup. This is essential to reduce the stress on the motor and provide the maximum service life for the industrial drive in the factory floor. This is because the surge current of the motor may be seven to ten times that of the working current, and the torque required for starting may be three times that of running.

VT130G2U4750 digital soft starter controller continuously monitors the voltage during the starting process, and adjusts according to the motor load to provide smooth acceleration, speed and torque control. This is used to start and stop the AC motor drive system and reduce the pressure on the driver. This also reduces the load of the power supply, reduces the energy consumption, and thus significantly saves the cost. AC drive interface AC drive interface can be realized by many different connection ways. These can be 4 to 20 mA current loops, 0 to 10 VDC voltage signals, or remote connections through Ethernet or wireless communication links.
