Motor speed calculation (rev/min)
The machine will need a maximum speed (rev/min motor) in a linear
movement of the table. Therefore, the motor must have a maximum
speed of:
V
max
is the maximum linear speed the table needs.
Select in the characteristics table of FAGOR synchronous motors
see “AC synchronous servo motors” manual. FXM/FKM families a motor
having:
• A stall torque equal to or greater than the calculated continuous torque
M
s
.
• A maximum turning speed equal to or greater than the calculated value
