Title: LINEAR MOTOR ASSEMBLY FOR AN ELEVATOR SYSTEM
Abstract:
The invention relates to a linear motor assembly which is suitable for an elevator system (1). The elevator system (1) comprises at least one car (2) which can be moved along a travel path (F), and the linear motor assembly is suitable for driving the car (2) in the direction of the travel path (F). The linear motor assembly comprises the following: - a rotor unit (5) with at least one rotor magnet (22), - a stator unit (4) with multiple stator magnets (21) arranged along the travel path (F), and - at least one securing unit (10) for drivingly connecting the rotor unit (5) to the car (2). The stator magnets (21) are designed to generate a magnetic field that propagates in the direction of the travel path (F) and by means of which the at least one rotor magnet (22) is acted upon magnetically for the purpose of driving the rotor unit (5). The rotor unit (5) is connected in a fixed manner at least when viewed in the travel direction (z) by means of the securing unit (10), and the securing unit (10) is designed to allow a relative movement between the rotor unit (5) and the car (2) in a direction (x, y) transverse to the travel direction (F).
