Abstract
An elevator drive for controlling an elevator system has an electric motor with a housing, the electric motor being a permanent magnet synchronous motor. The electric motor has a motor shaft that, on an axial portion of the shaft lateral surface outside the housing, has a drive zone for coupling to at least one support means of the elevator system. A ratio of a weight of the elevator drive to a nominal payload for which the elevator drive is designed is less than 0.2.
Claims16
An elevator drive for an elevator system, the elevator drive comprising:
- an electric motor having a housing, the electric motor being a permanent magnet synchronous motor;
- wherein the electric motor has a motor shaft extending from the housing, the motor shaft having a drive zone on an axial portion of a lateral surface of the motor shaft outside of the housing;
- wherein the drive zone is adapted to couple to at least one support means of the elevator system;
- and
- a circuit board arranged on the electric motor and extending perpendicularly to an axis of the motor shaft, the circuit board being arranged on a side of the electric motor facing away from the drive zone, and the circuit board having an inverter arranged thereon for electrically controlling the electric motor when the inverter is electrically connected to the electric motor.
