Publication number: 20220324079Abstract: A belt sander for sanding a workpiece and defining a center of gravity within a first plane. The belt sander includes a housing, a handle defining a second plane, and a drive unit disposed within the housing. The drive unit includes a motor disposed adjacent a first sidewall of the housing, a pulley system disposed adjacent a second sidewall of the housing opposite the first sidewall, and a transmission disposed between the motor and the pulley system. The belt sander further includes a belt drive system driven by the drive unit and including a drive wheel, a driven wheel, and a platen.

Patent number: 10960530Abstract: System for cooling a power tool. One exemplary power tool includes a housing including an air intake and an air exhaust. The power tool further includes a motor and a fan configured to pull cooling air into the housing through the air intake, and exhaust the cooling air out of the housing through the air exhaust. The power tool further includes a plurality of field-effect transistors (FETs). The FETs couple the stator coils to a power source. The power tool further includes a FET board within the housing. The power tool further includes a heat sink within the housing. The heat sink includes a first mounting portion and a second mounting portion. Each of the mounting portions includes a horizontal fin extending toward a respective side of the housing. A plurality of vertical fins extends from a top surface of each of the horizontal fins.Type: GrantFiled: March 29, 2017Date of Patent: March 30, 2021Assignee: Milwaukee Electric Tool CorporationInventors: Nikos A.
