However, it is observed that in many applications, the field orientation operate under constant flux for different amount of load torque and this reduces the efficiency of this control scheme. In this study, a loss model equation is developed for the three-phase induction motor to establish the...

6.1 Motor losses and efficiency expression Motor efficiency is a measure of the effectiveness with which electrical energy is converted to mechanical energy. Motor efficiency can be directly expressed as the ratio of power output to power input (see equation 6.1). The efficiency computed from this ...
The consumed electrical power of the motor is defined by the following equation: Pelet = Pin = I * V The efficiency of the motor is calculated as mechanical output power divided by electrical input power: Motor Efficiency = Pmech / Pelet = Pout / Pin If the motor has 100% efficiency all...
For effective pump-off control, 20 hours/day pumping time is a good rule of thumb. The maximum reservoir inflow capacity should be used for the desired daily rate. Example 10-1 illustrates this equation. Example 10-1 Design System Pumping Rate for POC (pump-off control) A gas well with ...
