AC Motor Choice

[Arno]

Hello,

Unfortunately, I did not have any time to devote for this project.
I still have the motors, nicely parked on a shelf in my garage, waiting for me to get some time...
This may not happen for a while...

Hi guys,does any one have a circuit diagram for the direction signals circuit to connect to the vfd.I know it either uses transistors or a octocoupler.Already have the pwm to analogue converter.Thanks so much.

There are a few basic criteria for selecting an AC motor. These involve common variables such as the operating speed and load torque, in addition to the power supply voltage and frequency. ... Next, calculate the required torque. In a single-phase induction motor, the starting torque is always lower than the rated torque.
