Problems solved by technology

Such stainless steel housings have the disadvantage that they have poor heat dissipation, so that compared to similar motors without stainless steel housings, the permissible power of the motor, mostly the motor, must be correspondingly reduced or must be reduced. The motor is made correspondingly larger

Embodiment Construction

[0025] figure 1 The electric machine 1 is shown in section with a housing provided with stainless steel coatings 16 , 17 . The electric machine 1 basically consists of two housing units. The main housing unit is basically composed of the first end cover 10, the stator lamination group 3 and the intermediate flange 12, and the manufacturing method of the main housing unit is in Figures 2 to 4 explained in detail. The housing unit thus forms a stator unit which has a common stainless steel coating in the form of a first stainless steel coating 16 . The second housing unit is essentially formed by the second end cap 11 , which likewise has a second stainless steel coating 17 . exist figure 1 The housing or electric machine 1 shown in is characterized in that the entire housing has a stainless steel coating 16 , 17 , which was produced by means of a generative manufacturing method. The stainless steel coating 16, 17 can be applied thinly, eg with a thickness of 1 to 3 mm. D...

Abstract

The invention relates to a housing unit (5) for a motor (1), in particular for a permanent magnet servomotor. It has a first end cap (10), an intermediate flange (12) and a first stator lamination stack (3). The thin-walled stainless steel housing of the motor can be obtained in a cost-effective and simple manner, ie the first end cap (10), the first stator lamination stack (3) and the intermediate flange (12) have a common stainless steel coating (16). Stainless steel coatings are produced by means of a generative manufacturing process. Therein, the housing unit (5) is formed by a first end cap (10), a stator lamination stack (3), an intermediate flange (12) and a common stainless steel coating (16).

Description

technical field [0001] The invention relates to a housing unit for an electric machine, in particular for a permanent magnet servo motor, having a first end plate, an intermediate flange and a first stator lamination pack. The invention also relates to an electric machine with such a housing unit and a method for producing such a housing unit. Background technique [0002] Such a housing unit is used, for example, in a permanent magnet servomotor (PM-Servomotor). In special cases of use it is required that the housing of the electric motor should or must be made of stainless steel. Such stainless steel housings have the disadvantage that they have poor heat dissipation, so that compared to similar motors without stainless steel housings, the permissible power of the motor, mostly the motor, must be correspondingly reduced or must be reduced. The motor is made correspondingly larger. Contents of the invention [0003] The object of the invention is to produce a thin-wall...
