Abstract

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).
