description Provided are a motor and a power tool, which belong to the technical field of power tools. The motor includes a stator assembly, a rotor assembly, and a terminal assembly. The stator assembly includes a stator core and a winding wound onto the stator core, where the winding includes an input end and an output end. The rotor assembly includes a rotor shaft extending along a direction of a first straight line. The terminal assembly is configured to connect or fix the input end and the output end. The stator core includes first-type laminations, where each of the first-type laminations is provided with connection arms and a special-shaped portion, special-shaped portions are configured to: when the first-type laminations are stacked along a direction parallel to the first straight line, form an access slot which is configured to connect the terminal assembly, and the access slot is disposed on an outer sidewall of the stator core. In the motor, a housing of the motor is fixed along a circumferential direction of the rotor shaft, thereby avoiding relative movement between the stator assembly and the housing of the motor along a direction of the rotor shaft during operation and improving operation stability of the motor.
