Variable Frequency Drive Motor

Three main data lead to the possibility of connecting a variable frequency drive. We need to know the power supply, single-phase 230 V or three-phase 400 V and be sure the combination machine holds three-phase motors then extracting the rated voltage from the motor nameplate.
single-phase 230 V input => three phase 230 V output A single-phase 230 V input to a variable frequency drive 230 V implies three-phase 230 V output which means 230 V rated-voltage motor. That device is also named variable frequency inverter and can only output three-phase 230 Volts.

three-phase 400 V input => three-phase 400 V output A three-phase 400 V input to a variable frequency drive 400 V outputs three-phase 400 V which means 400 V rated-voltage motor.

A variable frequency drive can not supply single-phase motor and dual-coil motors or some specific ones are not designed to work in conjunction with such device. On the other hand identical horsepower motors make the installation easier. The good news is most of woodworking combination machines accommodate several same horsepower motors.

Nameplate


Here are two schematic diagrams featuring single-phase and three-phase supplies connected to a matching variable frequency drive and three-phase output related to their supply. The terminal box of the motor shows delta or star connection depending on the output voltage of the variable frequency drive.

Delta Star Connection


There are so many solutions as regard motor brake that giving an answer about compatibility is pretty much impossible. With that said internal electromagnetic brakes most of time work with variable frequency drives. You may find an example in that document.
