Elevator drive
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.
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.
