We are looking for 12 V batteries in the 80-120 amp/hour range that have minimal maintenance, the battery will be used with solar systems. The systems will be installed in the desert in South California, where the temperature in summer can reach 50C or 125F .since, the temperature reduces the...
If you have a centrifugal pump, inverter duty motor and VFD, which bearings has the highest risk of failure(motor or pump), what kind of failures is expected and what are the steps needed to prevent these type of failures.
Are there any features that can be added when ordering the motor and...
motor losses are fixed losses + variable losses (I2R). I have around 100 amps output current from the VFD at different motor frequency. the current output from the VFD is equal to the current drawn by the motor? thus the heat generated at the motor is almost the same at different motor speed...
I am interested in motor cooling.
1) What's the key component in motor (induction motor) heat generation? is it the current (amps) or the input horse power and efficiency at a specific point. I read different articles and they all mention current losses in the motor (stator and Rotor), but...
