Publication number: 20250091184Abstract: A power tool includes an electric motor having a motor shaft and a fan assembly attachable to the motor shaft for rotation in a first rotational direction to generate an airflow for cooling the electric motor. The fan assembly includes a fan body, a bearing that rotates with the fan body, and a flywheel having a central portion that defines a central bore configured to receive the bearing so that the bearing is rotatably affixed to the flywheel. The power tool further includes a spring configured to receive torque from the electric motor such that the torque winds the spring to store energy when the electric motor is activated and release the energy to supply torque to the fan assembly so that the fan assembly continues to rotate and generate the airflow for cooling the electric motor when the electric motor is deactivated.Type: ApplicationFiled: December 3, 2024Publication date: March 20, 2025Inventors: Matthew R. Bailey, Will Didier, Jeffrey C. Hessenberger

Patent number: 12162124Abstract: A method of cooling an electric motor configured for use in a power tool. The electric motor has a motor shaft rotatable about a motor axis. The power tool further includes a fan assembly attachable to the motor shaft and an energy storage device coupled to the motor shaft and to the fan assembly. The method includes activating the electric motor to supply torque to the motor shaft. The method further includes rotating the motor shaft and the fan assembly about the motor axis. The fan assembly generates an airflow to cool the electric motor. Moreover, the method includes supplying torque from the electric motor to the energy storage device and deactivating the electric motor to stall rotation of the motor shaft. The fan assembly continues to rotate about the motor axis to generate the airflow after rotation of the motor shaft has ceased.Type: GrantFiled: April 24, 2023Date of Patent: December 10, 2024Assignee: MILWAUKEE ELECTRIC TOOL CORPORATIONInventors: Matthew R.
