摘要： A gas engine replacement device includes a housing, a battery receptacle coupled to the housing to receive a battery pack, a motor within the housing, a power take-off shaft receiving torque from the motor and protruding from a side of the housing, a power switching network configured to provide power from the battery pack to the motor, and an electronic processor coupled to the power switching network and configured to control the power switching network to rotate the motor and to receive a command speed, determine whether the command speed is in an exclusion zone, set an output speed at the command speed responsive to the command speed being outside the exclusion zone, set the output speed to a speed outside the exclusion zone responsive to the command speed being in the exclusion zone, and control the power switching network to rotate the motor in accordance with the output speed.

摘要： Bi-directional motor (36) for gas-engine replacement device (10). One embodiment provides a gas-engine replacement device (10) including a housing (14), a battery receptacle (54), a motor (36), a power take-off shaft (38) receiving torque from the motor (36), a power switching network (310) configured to selectively provide power to the motor (36), and an electronic processor (302) coupled to the power switching network (310). The electronic processor (302) is configured to rotate the motor (36) in a first direction and receive an input to switch a rotation direction of the motor (36). The electronic processor is also configured to control the power switching network (310) to stop the motor (36) and rotate the motor (36) in a second direction after controlling the power switching network (310) to stop the motor (36).
