Description: 压频比控制方法非常适用于风机和泵等负载变化较慢的
应用场合。但对于需要快速动态响应的应用场合则效果
不佳。特别是在速度或转矩发生快速变化时，由于较高
的转差率则会导致较大的瞬态电流。如果同时对电机转
矩和磁通进行闭环控制，则可以在不产生大电流的条件
下实现快速的动态响应。矢量控制技术可以实现上述目
标，通常也被称作磁场定向控制（FOC）。-Voltage to frequency ratio control method is very suitable for fan and pump applications where the load changes slowly. But the need for applications where fast dynamic response is ineffective. Especially in the speed or torque changes occur rapidly, due to higher slip will result in a larger transient current. If both the motor torque and flux for closed-loop control, you can not produce high current conditions to achieve fast dynamic response. Vector control technology can achieve these goals, also commonly referred to as field-oriented control (FOC). Platform: |

Description: It s pretty much common sense that if you turn a motor on and off fast enough, say
one running a fan, the fan s speed is going to be neither fully off nor fully on. It
would run at a reduced speed, and that speed would reflect the average amount of
time the switch was on. This is the essence of PWM, Pulse Width Modulation. PWM is
a way of getting analog (continuously variable) control over some types of devices.
Motors, incandescent lights, and LED s are three commonly PWM ed devices. Platform: |
