  • Publication number: 20210175479
    Abstract: Battery configuration for gas engine replacement device. One embodiment provides a gas engine replacement device (10) including a housing (14) and a first battery pack (50) and a second battery pack (50) connected to the housing (14). The gas engine replacement device (10) also includes a motor (36) within the housing (14) and a power switching network (310) coupled to the motor (36), the first battery pack (50), and the second battery pack (50) and configured to drive the motor (36). The gas engine replacement device (10) further includes an electronic processor (302) coupled to the power switching network (310) and configured to sequentially discharge the first battery pack (50) and the second battery pack (50) to the power switching network (310) to drive the motor (36).

  • Publication number: 20210148126
    Abstract: A concrete vibrator includes a frame, a strap coupled to the frame, a main housing supported upon the frame, and an electric motor coupled to the main housing. The concrete vibrator further comprises a flexible shaft having a first end coupled to the motor and an opposite, second end. The concrete vibrator further comprises a vibrator head coupled to the second end of the shaft, the vibrator head configured to receive torque from the motor and the shaft to cause the vibrator head to vibrate. The concrete vibrator is operable in a backpack configuration in which the strap is used to carry the concrete vibrator with the frame in a vertical orientation, and in a briefcase configuration in which the frame is supportable in a horizontal orientation.

  • Publication number: 20210143375
    Abstract: 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.

  • Publication number: 20210140130
    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).
