Abstract
A construction machine includes a turning electric motor configured to drive a turning mechanism configured to cause an upper-part turning body to turn relative to a lower-part traveling body and a control unit configured to control driving of the turning electric motor. The control unit is configured to cause the output of the turning electric motor to continue after the turning speed of the upper-part turning body becomes zero, based on the magnitude of the output or the direction of the output of the turning electric motor at the time when the upper-part turning body is decelerated and its turning speed becomes zero.
