Embodiment Construction

[0035] figure 1 Shown is an electric motor 1 of the same type according to the prior art, which is provided and designed for driving a centrifugal pump (not shown) and is mechanically fixedly connected thereto. The electric motor 1 has a cylindrical motor housing 3 made of metal, here die-cast aluminum, which comprises a drive-side first axial end 4 and a second opposite end. Axial end 5. The two axial ends 4 , 5 are designed as open, and a rotatably mounted motor shaft 8 extends through the first axial end 4 toward the centrifugal pump. For example, this end of the motor shaft can be connected in a rotationally fixed manner to the pump shaft of the centrifugal pump, the drive shaft of the transmission or a coupling shaft between the electric motor and the centrifugal pump. The stator 7 with the electrical winding is axially pushed into the motor housing 3 with a force fit from the second axial end side. The motor shaft 8 bears a dry-running rotor 9 arranged in the stator 7...

Abstract

The invention relates to an electric motor (1). The motor comprises a metal cylindrical motor shell (3), wherein the motor shell is provided with a first axial end part (4) and a second axial end part(5); the first axial end part is provided with a central opening (6); a rotatably supported motor shaft (8) passes through the central opening; wherein the stator (7) is pushed into the motor housingin the axial direction by means of a second axial end, the motor shaft (8) supports a rotor (9) which is arranged in the stator and operates in a dry mode. And a second axial end, wherein a metal mounting flange (2), which is independent of the motor housing (3), is arranged on the end face of the motor housing, the motor housing integrally transitions at a first axial end into a radially inwardly oriented annular housing flange (10), on which the mounting flange rests, the housing flange having a bearing receptacle in which a rolling bearing (14) for supporting the motor shaft is received, the outer circumference of which rolling bearing engages directly in the bearing receptacle.

Description

technical field [0001] The invention relates to an electric motor for driving a centrifugal pump and mechanically fixedly connected thereto, comprising a cylindrical motor housing made of metal having a drive-side first axial end and a The second axial end opposite the first axial end has a central opening through which the rotatably mounted motor shaft passes, and the stator is axially driven by the second axial end. Pushed into the motor housing, the motor shaft bears the dry-running rotor arranged in the stator, and at the first axial end a metal mounting flange which is independent of the motor housing is placed, in particular screwed on On the end face of the motor housing, the mounting flange serves for the direct or indirect screwed fastening of the centrifugal pump to the electric motor and protrudes radially outward at least in sections relative to the motor housing. Background technique [0002] The invention relates in particular to so-called standard electric mo...
