Abstract

An electric motor (1) and drive arrangement (3) for a furniture device (5), which electric motor comprises a stator (10) and a rotor (12) adapted to be set into rotation in relation to the stator. The motor further comprises an elongated motor shaft (14) comprising a first end part (30) and a second end part (32) fixedly joined to the rotor so that the first end part, the second end part and the rotor rotate with said same speed, and a cover (36) enclosing the stator and the rotor. The cover comprises a first opening (38) through which the first end part of the shaft extends in a first direction and a second opening (40) through which the second end part of the motor shaft extends in a second direction. The second direction is opposite to the first direction.

Description

technical field [0001] The invention relates to an electric motor for a furniture installation. The electric motor includes a stator and a rotor rotatable relative to the stator. The motor also includes an elongated motor shaft having a first end fixedly engaged to the rotor such that the first end and the rotor rotate at the same speed, and a shroud surrounding the stator and the rotor. The shroud includes a first opening through which the first end of the shaft extends in a first direction. [0002] The invention also relates to a drive arrangement for a furniture device comprising an electric motor. The invention also relates to a furniture arrangement comprising a drive arrangement. Background technique [0003] Prior art drive arrangements for furniture pieces are such that the drive arrangement comprises a plurality of electric motors for reorienting the furniture piece in order to provide comfort to the user. For example, electric motors are used to displace the b...
