FIELD: electricity.
SUBSTANCE: fixed part of the electrical machine consists of laminated magnetic core stacked out of separate steel insulated plates jointed into a pack by weld seams made at outer side of the magnetic core. The magnetic core is fixed in the housing by spline connection centred along lateral surfaces. In the housing there is a cooling main placed in the middle part of the magnetic core from outside. Between the housing and the stator magnetic core there is a circular cooling chamber divided by splines into circular sectors insulated from each other, at that cooling liquid is supplied from the cooling main. The rotatable part consists of the magnetic core, as boss and a setting disc of the rotor angular position sensor having circular toothed surface shaped as a truncated cone.
EFFECT: design of an electrical machine with forced liquid cooling having high power performance and low noise level.
