A radial flux permanent magnet elevator motor includes a motor frame forming the stator frame having fixing points to be fixed to an elevator guide rail, which frame has a back wall facing and/or abutting with the guide rail, which motor frame includes an axially extending flange protruding away from the back wall in the direction of the rotor, and which motor frame includes at least one axially extending first wall section in a defined radial distance from the axis of the motor frame, which first wall section is configured to support a stator winding of the motor. The rotor includes a central hub protruding into the flange of the motor frame and is rotatively supported within the flange via bearings, which rotor includes a traction sheave in a first radial distance from the motor axis and a ring-like support wall in a second radial distance from the motor axis for supporting permanent magnets, which second distance is larger than the first distance, and whereby the stator winding and the permanent magnets form a radial air gap.

A brake assembly for an elevator includes a brake, a brake operating device and a first brake wire connected to the brake operating device and to the brake, the brake operating device being configured to release the brake by moving the brake operating device and the first brake wire to a first direction. A second brake wire is connected to the brake operating device and to the brake, and the brake operating device is configured to engage the brake by moving the brake operating device and the second brake wire to a second direction.
