• Calculating the Combined Torque and Effective Torque
*
●Selecting the Motor
Use the results of the calculations above and the equations
below to determine the required motor capacity from the effective
torque and maximum torque. Use the larger of the following
motor capacities when selecting the motor.
When selecting the motor, set a motor capacity higher than the
calculated capacity to provide some extra capacity.
• Motor Capacity Supplied for Effective Torque:
• Motor Capacity Supplied for Maximum Torque:
Effective torque: T
Maximum torque: T
Motor capacity (kW): 1.048

Selecting the Inverter Capacity
Select an Inverter that is large enough to handle the motor
selected in Selecting the Motor above. Basically, select an
Inverter with a maximum motor capacity that matches the motor
capacity calculated above.
After selecting the Inverter, verify that the following conditions
are satisfied. If the conditions are not satisfied, select the Inverter
that is one size larger and check the conditions again.
• Motor’s rated current ≤ Inverter’s rated output current
• The application’s continuous maximum torque output time ≤
Note 1. If the Inverter's overload endurance is 120% of the rated output current
1 minute
2. Use an Inverter that is one size larger than determined by the condi-
for one minute, check for 0.8 minute.
tions above if open-loop vector control with PG is being used and a
holding torque is required at 0 r/min or a torque that is 150% or more of
the rated torque is required regularly at low frequencies (10 Hz or less).
