MVME61006E-0163 直流调速器 能量功率能得到充分利用

MVME61006E-0163 直流调速器是一种电机调速装置，用于调节直流电动机的速度。其工作原理是将交流电转化为两路直流电，一路给到直流电机的励磁（定子），一路给到直流电机的电枢（转子）。通过控制电枢的直流电压来调节直流电机的转速。同时，直流电机给直流调速器一个反馈电流，直流调速器根据反馈电流的大小来判断直流电机的转速情况，必要的情况下，直流调速器会修正给到直流电机电枢的电压，以达到修正直流电机转速的目的。直流调速器具有体积小、重量轻等特点，可单独使用也可直接安装在直流电机上构成一体化直流调速电机。其应用广泛，包括工业直流电机调速、工业传送带调速、灯光照明调解、计算机电源散热、直流电扇等。此外，直流调速器还采用脉宽调制（PWM）原理进行制作，通过改变输出方波的占空比使负载上的平均电流功率从0-100%变化，从而改变负载、灯光亮度/电机速度。这种方式的优点是电源的能量功率能得到充分利用，电路的效率高。MVME61006E-0163 直流调速器在使用过程中可能会产生谐波，这是由于其主电路的转速环、电流环一般采用三相6脉冲晶闸管进行整流，导致直流调速器交流测所吸收的电流波形并非正弦波，进而产生谐波。因此，在选择和使用直流调速器时，需要综合考虑其性能、应用场景、谐波影响等因素。

MVME61006E-0163 DC Governor is a motor speed control device used to regulate the speed of DC motors. Its working principle is to convert alternating current into two paths of direct current, one for the excitation (stator) of the direct current motor and the other for the armature (rotor) of the direct current motor. Adjust the speed of the DC motor by controlling the DC voltage of the armature. At the same time, the DC motor provides a feedback current to the DC speed controller, which determines the speed of the DC motor based on the magnitude of the feedback current. If necessary, the DC speed controller will correct the voltage supplied to the armature of the DC motor to achieve the purpose of correcting the speed of the DC motor. DC speed controllers have the characteristics of small size and light weight, and can be used alone or directly installed on DC motors to form an integrated DC speed control motor. It has a wide range of applications, including industrial DC motor speed regulation, industrial conveyor belt speed regulation, lighting regulation, computer power cooling, DC fans, etc. In addition, the DC speed controller is also manufactured using the pulse width modulation (PWM) principle, which changes the duty cycle of the output square wave to change the average current power on the load from 0 to 100%, thereby changing the load, light brightness/motor speed. The advantage of this method is that the energy and power of the power supply can be fully utilized, and the efficiency of the circuit is high. The MVME61006E-0163 DC speed controller may generate harmonics during use. This is because the speed and current loops of its main circuit are generally rectified using three-phase 6-pulse thyristors, resulting in the current waveform absorbed by the AC measurement of the DC speed controller not being a sine wave, which in turn generates harmonics. Therefore, when selecting and using a DC speed controller, it is necessary to comprehensively consider its performance, application scenarios, harmonic effects, and other factors.
