A high voltage electric machine and power distribution system including one or more of such electric machines are provided. In one aspect, a high voltage electric machine includes a stator, a rotor, and a housing encasing at least a portion of the stator and rotor. The stator is modularized into cascaded voltage stator modules. The stator modules are galvanically isolated from one another by intermodular separators. At least one intermodular separator is positioned between each adjacent pair of stator modules. The stator modules are also galvanically isolated from the housing by a housing separator. The housing separator is positioned between the stator modules and the housing. Each stator module has an associated set of windings that are wound only within their associated stator module.

An electric work machine, such as a lawn mower includes a motor case (22) fixed inside a main-body housing (10). A brushless motor (21) is housed inside the motor case (22) and includes a stator (23) having a stator core (40), coils (45), and upper and lower insulators (42, 43), and a rotor (24) disposed inward of the stator (23) and having a rotary shaft (25). A spindle (17) is driven by the rotary shaft (25). The motor case (22) holds the stator (23) and axially supports the rotary shaft (25) via bearings (68, 76). One or more insulating members, such as an insulating cap (67) and/or a resin layer (78), provide electrical insulation between the stator core (40) and the rotary shaft (25).

A motor comprises a housing having a cylindrical recess for receiving and centering a cylindrical wound stator The stator has an overmolded electrical connection assembly with connecting tabs extending transversely. The stator, being equipped with the electrical connection assembly, is overmolded with an electrically insulating resin. The housing has a lateral protrusion for connecting with a complementary connection assembly. The housing has, in its rear portion, a first angular wedging means complementary to a second angular wedging means provided at the rear portion of the overmolded electrical connection assembly.

A motor includes: an electrically conductive case; a shaft stored in the case and placed such that a part of the shaft penetrates the case; and a bearing via which the shaft is rotatably attached to the case. The shaft has an electrically conductive shaft material, and a high-resistance layer covering a surface of the shaft material and having a higher electric resistance than the shaft material.

An electromotive drive for motor vehicle applications. In particular, the electromotive drive is part of a locking device of an electric connection device for electric or hybrid motor vehicles. For this purpose, an electric motor and a multistage transmission which is arranged downstream of the electric motor are provided as drive elements for acting on an actuating element, and a drive housing which houses drive elements is also provided. The actuating element is a locking element of the locking device for example. The drive housing is equipped with inner and/or edge-side protrusions. The protrusions have direct bearing points for individual drive elements or all of the drive elements.

A motor includes a rotor, a stator, and a case in which the rotor and the stator are stored. The rotor is electrically insulated from the case. Further, the stator may be also insulated from the case.
