Latest Patents

One of Renz's latest patents is an electric drive motor for a work apparatus. This innovative motor features a stator with two stator poles that are spaced apart in the circumferential direction, each equipped with respective field windings. The rotor rotates between these stator poles, and its rotor shaft drives a fan wheel. The cooling-air flow generated by the fan wheel enters the stator, flows through it, and is discharged. To enhance cooling efficiency, a pole intermediate space is provided between the stator poles, filled with a non-magnetic guide body that creates a cooling duct.

Another notable patent is for a hand-held power tool. This tool includes a motor that is drivingly connected to a tool member, all housed within a motor housing. A battery powers the tool member, while a guide shaft connects the battery to the motor housing and tool member. The design incorporates a rotatable power output part that connects to the motor, allowing for effective operation. Cooling air is drawn through the guide shaft into the motor housing, exiting through an annular air exit gap, which is enhanced by guide vanes.
