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).
