To provide a motor-driven roller capable of easily performing speed control while reducing a change from a conventional machine during motorization, and of improving a contribution to a decarbonization society, the improvement of a work environment, and maintainability.SOLUTION: A motor-driven roller includes rolling pressure wheels, a vehicle body frame 2 for rotatably supporting the rolling pressure wheels, rolling pressure wheel electric motors for driving the respective rolling pressure wheels, rolling pressure wheel invertors for controlling the rotation speeds of the respective rolling pressure wheel electric motors, a hydraulic cylinder 55 for turning operation, a motor-driven hydraulic pump 52 for driving the hydraulic cylinder 55 in linkage with the operation of a steering by an operator, a battery K for supplying electric power to each of the rolling pressure wheel electric motors, the rolling pressure wheel invertors, and the motor-driven hydraulic pump 52, and a control part 3 for outputting signals to the rolling pressure wheel invertors according to the inclination of a forward-backward lever 17. No internal combustion engine is provided, and a power source for the rolling pressure wheels is the battery only.SELECTED DRAWING: Figure 4

    【課題】電動化を図る際に、従来機との変更を小さくしつつ速度制御を容易に行うことができるとともに、脱炭素社会への貢献、作業環境の改善及びメンテナンス性の向上を図ることができる電動ローラを提供する。【解決手段】転圧輪と、転圧輪を回転可能に支持する車体フレーム2と、転圧輪を駆動させる転圧輪用電動モータと、転圧輪用電動モータの回転数を制御する転圧輪用インバータと、旋回させるための油圧シリンダ55と、オペレーターによるステアリングの操作に連動し、油圧シリンダ55を駆動させる電動油圧ポンプ52と、転圧輪用電動モータ、転圧輪用インバータ及び電動油圧ポンプ52に電力を供給するバッテリKと、前後進レバー17の傾きに応じて転圧輪用インバータに信号を出力する制御部3と、を有し、内燃機関を備えておらず、転圧輪の動力源をバッテリKのみとすることを特徴とする。【選択図】図4
