  • the brake 5 is with a Unlocking lever 22 is provided, which can be remotely operated.
  • the brake shoes 21 can interact with a limit switch, to on the basis of the pivot position of the brake shoes 21 when tightened Brake over wear of the brake pads to be able to determine the specified dimension.
  • the stator housing 9 is transverse over a conical circumference slotted clamping ring 23 in a receiving ring area of the frame 1 firmly clamped. As a result, a good heat conduction from the stator housing 9 into the frame 1 respectively. In this way, the frame 1 also receives one Cooler function.
  • the frame 1 is above and below, respectively provided with mounting flanges 24, in particular can be carried out in the same way. Through these flanges 24 are different fastening options in the elevator system possible.
  • the invention relates to a drive for elevators with a electromotive driven traction sheave and busy starting from a closest, generic State of the art according to US 5,435,209 for those for the states BE, FI, LU and NL applicable claims with the problem of such Drive as small as possible, simple and versatile mountable and working with high efficiency create.
