A fan motor system comprising: a fan motor unit including a motor, a fan configured to be rotated by the motor, and a controller configured to control a rotational speed of the motor in accordance with an input command value; a command value outputting unit configured to output the command value to the controller while increasing the command value from a predetermined initial value when the motor in a stopped state is activated; a start detecting unit configured to detect a start of rotation of the motor on the basis of an observed value of the rotational speed of the motor; a start command value recording unit configured to acquire a rotation start command value, which is the command value output by the command value outputting unit at a timing corresponding to a timing at which the start of rotation is detected, and to record the acquired rotation start command value on a recording medium; and an operation mode switching unit configured to switch an operation mode to a normal mode or an inspection mode, wherein the start command value recording unit records a plurality of rotation start command values acquired in correspondence with a plurality of activations of the motor if the operation mode is the normal mode and rewrites and records the rotation start command value acquired when the motor is activated from the recorded rotation start command value if the operation mode is the inspection mode, and wherein the command value outputting unit determines an initial value on the basis of one or more rotation start command values recorded on the recording medium when the motor is activated. a fan motor unit including a motor, a fan configured to be rotated by the motor, and a controller configured to control a rotational speed of the motor in accordance with an input command value; a command value outputting unit configured to output the command value to the controller while increasing the command value from a predetermined initial value when the motor in a stopped state is activated; a start detecting unit configured to detect a start of rotation of the motor on the basis of an observed value of the rotational speed of the motor; a start command value recording unit configured to acquire a rotation start command value, which is the command value output by the command value outputting unit at a timing corresponding to a timing at which the start of rotation is detected, and to record the acquired rotation start command value on a recording medium; and an operation mode switching unit configured to switch an operation mode to a normal mode or an inspection mode, wherein the start command value recording unit records a plurality of rotation start command values acquired in correspondence with a plurality of activations of the motor if the operation mode is the normal mode and rewrites and records the rotation start command value acquired when the motor is activated from the recorded rotation start command value if the operation mode is the inspection mode, and wherein the command value outputting unit determines an initial value on the basis of one or more rotation start command values recorded on the recording medium when the motor is activated.
