Driving system for elevator

The drive system has a linear motor (3) for a lift system (1), whereby the cabin (2) is guided in a shaft (4) by guide rails (5) and driven directly by the linear motor. The linear motor is a flat, one-sided motor with permanent magnets (11). A secondary element (10) is mechanically attached to the cabin and a primary element (12) is mechanically attached to the shaft, or vice-versa. The permanent magnets of the secondary element are rare earth magnets, esp. of neodymium. The permanent magnet linear synchronous motor has a pulse width modulator with a microprocessor and an H-bridge with eight IGBT/MOSFETs.
