The invention provides an electric transport vehicle capable of appropriately controlling short-circuit braking of the electric transport vehicle. An electric transport vehicle according to one embodiment of the present invention is provided with a motor and a control circuit. The motor includes a plurality of terminals. The control circuit causes the motor to generate a braking force by means of a short-circuit brake in which two or more terminals among the plurality of terminals are short-circuited to each other, in response to a driving condition of the motor not being satisfied. The control circuit gradually reduces the braking force of the short-circuit brake in response to a change from a state in which the driving condition is not satisfied to a state in which the driving condition is satisfied.
本发明提供一种电动搬运车,能够适当地控制电动搬运车的短路制动。本发明的1个方案的电动搬运车具备:马达以及控制电路。马达具备多个端子。控制电路与马达的驱动条件未成立相对应地,通过使多个端子之中的2个以上的端子相互短路的短路制动,来使马达产生制动力。控制电路与从驱动条件未成立的状态向驱动条件成立的状态变化相对应地,使短路制动的制动力渐渐地降低。
