  • Patent number: 11979049
    Abstract: An electric work machine (1), such as a power tool, comprises a motor (50), a manipulatable part (12) such as a trigger switch, and a control part (36). The motor is energized with electric current supplied by a battery pack (22). By manipulating the manipulatable part, the control part energizes the motor. The control part also acquires information concerning the state of the battery from the battery pack, and, if appropriate based on the information obtained from the battery pack, takes measures (such as limiting a discharge current) to restrain, delay and possibly avert the performance of a protection (discharge-prohibited) operation by the battery pack.

  • Patent number: 11973449
    Abstract: A motor system includes a driving circuit, a motor device and a control circuit. The driving circuit outputs a driving current according to multiple control signals. The motor device drives a rotor unit to rotate according to the driving current, and includes a first sensor and a second sensor to sense the polarity of the rotor unit in different directions to generate polarity data. The control circuit receives the polarity data. When the polarity data is in a first state, the control circuit records a first maintenance time. When the polarity data changes from the first state to a second state, and a second maintenance time for the second state corresponds to the first maintenance time, the control circuit sets the polarity data to a third state, until the polarity data is changed from the third state to a fourth state.
