Abstract
A motor selection apparatus includes: a mechanical condition obtainment unit that obtains information pertaining to a distance between a center of mass of a workpiece and a rotation center of a motor; an operating pattern obtainment unit that obtains information pertaining to an operating pattern; a motor information obtainment unit that obtains information pertaining to instantaneous torque; an eccentric load torque calculation unit that calculates eccentric load torque, which is load torque acting on the motor in accordance with the rotation phase of the motor; an acceleration/deceleration torque calculation unit that calculates acceleration/deceleration torque; a required torque calculation unit that calculates a required torque from a sum of the eccentric load torque and the acceleration/deceleration torque; and a motor selection unit that determines whether a motor can be selected, based on whether the required torque is less than or equal to the instantaneous torque of the motor.
