Motor Torque and Current To work out the solutions, we must start with the basic calculation of the motor’s torque and current. The 5252 Conversion Factor When calculating the motor-rated torque or the Full Load Torque (FLT) of the motor, use the constant 5252. The number 5252 represen...

The discrepancy in magnet strength results in a field orientation calculation error. However, homopolar, switched reluctance and synchronous reluctance motors are robust in temperature variations since they do not have an electric circuit or magnets on the rotor. When considering the possibility of ...
Machine inertias are harder to define, since each manufacturer uses slightly different geometry (and possibly materials) - the inertia can be found using waross' calculation. Once you have the inertia OF THE DRIVE TRAIN, you can figure out how long it will take to accelerate based on the ...
