Adding a variable-frequency drive (VFD) upstream of an AC motor can lower energy use, reduce peak demand and improve power factor in many applications. Reducing motor speed at startup and during operation can cut maintenance costs, increase uptime and extend equipment life.

The correct sizing of the variable frequency drive (VFD) system depends on the knowledge of the behavior of the load type, that is, how the load is related with speed and consequently how much torque is demanded on the motor shaft. In most processes the variable frequency drive load type may be described by one of the following terms: variable torque, constant torque and constant horsepower.

1. able to manipulate the torque speed curve, allowing u start with a much higher torque. Wound motors are suitable for application with heavy starting duties such as ball/sag mills, crushers etc. Typically LRS in these situations are used to start only, and when motor has reached a certain speed, the rotor is short circuited and it acts like an squirrel cage motor.

In VFD supplied motor applications, it is important to note that torque-speed curves show the torque the motor can produce for each frequency, but not for how long and if motor can operate in each condition continuously. If in a VFD supplied motor application, a standard induction motor is used, heat limitations need to be taken into consideration.
