Abstract
An electrical machine is disclosed. The electrical machine has a first part and a second part, the first part moveable relative to the second part. One of the first part and the second part has a plurality of cores for current-carrying windings. Each core is of soft magnetic composite material (SMC) and is shaped to be no wider at its ends than along its length.
Claims19
A rotating or linear electrical axial flux machine comprising a first part and a second part, the first part moveable relative to the second part, one of the first part and the second part having a plurality of cores for current-carrying windings, wherein each core is of powder soft magnetic composite material (SMC) and is shaped to be no wider at its ends than along its length.
A method for manufacturing a core of an electrical axial flux machine wherein each core of the electrical axial flux machine is made of soft magnetic composite material (SMC) and is shaped to be no wider at its ends than along its length, wherein the method comprises
- (a) compressing SMC powder to form a first part of substantially uniform density,
- (b) compressing SMC powder to form a second part of substantially uniform density, and
- (c) compressing the first part and the second part together to form a core of substantially uniform density.
A method for manufacturing a core of an electrical axial flux machine wherein each core of the electrical axial flux machine is made of soft magnetic composite material (SMC) and is shaped to be no wider at its ends than along its length, wherein the method comprises gradually building up a part, by placing SMC powder in a die, compressing the powder using a punch, withdrawing the punch, adding more SMC powder, and compressing this, to finally build the core.
