Summary of the three pre-selections
• Maximum speed equal to or greater than calculated value in RPM
motor
• Stall torque equal to or greater than calculate continuous value M
contin-
uous
• Motor inertia equal to or greater than inertia J
LOAD
/ k
•
Peak torque equal to or greater than calculated value M

• Rated torque equal to or greater than calculated RMS value M
rms
Drive selection
Once the motor has been selected, check the electrical characteristics ta-
ble in the
FXM/FKM AC servomotors manual.
There are several drives available for each motor and the peak torque ob-
tained with each one of them will be different.
A drive has to be chosen whose peak current is greater than the one cal-
culated for the application.
