Abstract: For improved water resistance, the stator assembly of a d.c. brushless motor is encapsulated in an overmolding formed from a mixture of a thixotropic, flexible epoxy resin and glass fibers. The overmolding may be applied to the stator assembly by a vacuum pressure impregnation process. The overmolding may also encapsulate a Hall effect circuit board and sensors of the motor.

Abstract: A motor includes a rotor having a plurality of pole magnets angularly spaced about the rotor's rotational axis through an angle of 360°, and a stator including a plurality of windings angularly spaced about the rotational axis through an angle less than 360° to provide an angular section free of windings, wherein at least one of the plurality of pole magnets is not radially opposite any of the plurality of windings at any given rotational position of the rotor. The motor is designed for use in powering a horizontal blade reel of a cylindrical lawn mower, and includes a housing having a cross-sectional shape in the form of a chord-truncated circle, such that the housing has a flat portion corresponding to the angular section free of windings. The truncated motor housing avoids unattractive “layover” of grass during mowing.

Abstract: A combined d.c. brushless motor and drive control assembly for a rotary mower includes a hollow motor housing, a cover removably attached to an open rear end of the housing, and an end shield mounted to an internal shelf of the housing adjacent its rear end. The end shield and a front wall of the housing define rotary bearing seats for a motor drive shaft. An electronic circuit board including motor drive electronics and feedback sensors is mounted to the housing or to the cover, and is positioned at an axial location between the internal shelf of the housing and the rear wall of the cover. The housing is configured for mounting on a shroud of the rotary mower such that at least the removable cover is above the shroud and easily accessible, whereby repair or replacement of the electronic circuit board is facilitated.

Abstract: A magnetic drive assembly includes a housing having a cylindrical end bell portion and a cylindrical hub portion adjacent the end bell portion, wherein the radius of the hub portion is greater than the radius of the end bell portion. One or more mounting tabs extend radially outward from the hub portion. The housing has heat transfer fins associated with the mounting tabs for dissipating heat and structurally supporting the mounting tabs in the manner of a gusset. The heat transfer fins may be arranged on opposite sides of each mounting tab to provide support for the mounting tab in opposite axial directions of the housing. To relieve internal pressure, the housing may have at least one pressure equalization vent allowing passage of gas but not passage of liquid into and out of the housing.

Abstract translation: 磁驱动组件包括具有圆柱形端部钟形部分和与端部钟形部分相邻的圆柱形毂部分的壳体，其中毂部分的半径大于端部钟形部分的半径。 一个或多个安装翼片从轮毂部分径向向外延伸。 壳体具有与安装凸片相关联的传热翅片，用于散热并且以角撑板的方式在结构上支撑安装凸片。 传热翅片可以布置在每个安装翼片的相对侧上，以在壳体的相反的轴向方向上为安装翼片提供支撑。 为了减轻内部压力，壳体可以具有允许气体通过的至少一个压力平衡排气口，但不允许液体进入和流出壳体。
