Abstract
An electric motor (1) has a stator (3), a rotor (2) and a number of permanent magnets (6). The use of permanent magnets (6) having a cuboidal shape, without impairing performance. The stator (3) has a number of permanent magnets (6) having a cuboidal shape, which are embedded in recesses (7) and whose axial length (8) is greater than the axial length (4) of the stator (3).
Claims18
An electric motor comprising a rotor and a stator,
- wherein the diameter of the stator is greater than the axial length of the stator,
- the rotor and the stator have essentially the same length, the stator comprises a number of cuboidal-shaped permanent magnets embedded in pockets, of which an axial length is greater than an axial length of the stator, wherein the stator comprises a number of pole shoes corresponding to the number of permanent magnets, each connected to by two webs to a yoke and which, between themselves and the yoke, form the pockets for accommodating the permanent magnets.
An method for providing an electric motor comprising a rotor and a stator, wherein the diameter of the stator is greater than the axial length of the stator,
- the rotor and the stator have essentially the same length, comprising the step of providing the stator with a number of cuboidal-shaped permanent magnets embedded in pockets, wherein an axial length of each cuboidal-shaped permanent magnet is greater than an axial length of the stator, further comprising the step of providing the stator with a number of pole shoes corresponding to the number of permanent magnets, each connected by two webs to a yoke and which, between themselves and the yoke, form the pockets for accommodating the permanent magnets.
A direct-current motor with brushes comprising a rotor and a stator,
- wherein the diameter of the stator is greater than the axial length of the stator,
- the rotor and the stator have essentially the same length, the stator comprises a number of cuboidal-shaped permanent magnets embedded in pockets, of which an axial length is greater than an axial length of the stator,
- wherein the stator comprises a number of pole shoes corresponding to the number of permanent magnets, each connected to by two webs to a yoke and which, between themselves and the yoke, form the pockets for accommodating the permanent magnets.
