Abstract

An electric motor for an elevator drive comprises a motor housing; a number of motor windings which are connected to at least one terminal; ribs or webs being arranged on the motor housing; and the at least one terminal is arranged between the ribs or webs.

Claims

1. An electric motor for an elevator drive comprising:

an internal rotor rotatable inside a stator;

a motor housing disposed around the electric motor;

a number of motor windings which are connected to at least one terminal;

first and second ribs arranged on the motor housing such that the first and second ribs form a space between the first and second ribs as a type of cable duct on the motor housing;

the at least one terminal is arranged in the space between the first and second ribs; and

the motor windings are passed out of the motor housing and laid between the ribs.

2. The electric motor as claimed in claim 1, wherein the motor is in a form of a synchronous motor, with the motor windings being connected to the at least one terminal.

3. The electric motor as claimed in claim 1, wherein the ribs are arranged in a circumferential direction.

4. The electric motor as claimed in claim 1, wherein the ribs have a profile that does not exceed a predetermined height above a housing surface.

5. The electric motor as claimed in claim 1, wherein a plurality of terminals are arranged between the ribs.

6. The electric motor as claimed in claim 5, wherein the terminals are arranged adjacent one another between the ribs or one behind the other in a circumferential direction.

7. The electric motor as claimed in claim 5, wherein the terminals are arranged adjacent one another between the ribs, and one behind the other in a circumferential direction.

8. The electric motor as claimed in claim 1, wherein connections of the motor windings are arranged between the ribs.

9. The electric motor as claimed in claim 1, wherein motor connecting cables lead downward away from the at least one terminal.

10. The electric motor as claimed in claim 1, wherein edges of the ribs point away from the motor housing and are connected to one another by a cover.

11. The electric motor as claimed in claim 1, wherein the ribs are used as supporting ribs in order to make the motor housing robust.

12. A motor housing for an electric motor having an internal rotor rotatable within a stator, comprising:

first and second ribs arranged on the motor housing such that a space is formed as a type of cable duct between the first and second ribs and at least one terminal arranged in the space between the first and second ribs; and

the ribs are configured for laying between the ribs motor windings passed out of the motor housing.
