Power tool and electronic control device

An electric tool includes an output member, a motor, and a housing. The motor includes a rotor shaft, a rotor core, and a stator component. The rotor shaft is configured to rotate around a first axis. The stator component includes a coil winding. The stator component surrounds the first axis to separate the accommodation cavity into a first space and a second space. The first space includes a first end and a second end. The motor further includes a first end cover and a second end cover. The first end cover is disposed at the first end of the first space. The second end cover is disposed at the second end of the first space. A passage is formed between the second end cover and a structure surrounding the first space, and the passage is configured to place the first space into communication with the second space.
