PROBLEM TO BE SOLVED: To provide a control device of a traction motor for a forklift, which can make the forklift carry out energy saving operation such that the forklift does not exceed a prescribed maximum speed, while suppressing deterioration of work efficiency.SOLUTION: A control device 30 of a traction motor for a forklift comprises an inverter 40 and a controller 60. A microcomputer 61 of the controller 60 sets a first threshold as the maximum speed in an initial acceleration region of the forklift. The microcomputer 61, when determining that a running time of the forklift exceeds an intermediate travel region which is set following to the initial acceleration region and is longer than the initial acceleration region, sets as the maximum speed a second threshold larger than the first threshold.SELECTED DRAWING: Figure 2

    【課題】作業効率の悪化を抑制しつつフォークリフトが定められた最大速度を超えないように省エネ運転をさせることができるフォークリフト用走行モータの制御装置を提供する。【解決手段】フォークリフト用走行モータの制御装置30は、インバータ40とコントローラ60とを備える。コントローラ60のマイコン61は、フォークリフトの初期加速領域においては最大速度として第1の閾値を設定する。マイコン61は、フォークリフトの走行時間が初期加速領域に続いて設定される初期加速領域よりも長い中間走行領域を超えたと判断すると最大速度として第1の閾値よりも大きな第2の閾値を設定する。【選択図】図2
