Verify that the motor chosen in previous selections meets the following
condition:
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
CONTINUOUS
Motor inertia equal to or greater than inertia J
LOAD
/ K
Peak torque equal to or greater than calculated value M
MAX
Rated torque equal to or greater than calculated RMS value M
RMS
Drive selection
Once the motor has been selected, check the electrical characteristics table
in the FXM/FKM AC servomotors manual.
There are several drives available for each motor and the peak torque
obtained with each one of them will be different.
Select the drive that can provide a motor peak torque greater than the
maximum torque required in the application and whose rated current is
equal to or greater than the rated current of the motor.
Peak torque equal to or greater than the calculated max. torque:
