Abstract

The invention provides a reluctance well. The reluctance well comprises a guide groove formed in the sidewall of a lift well, an electromagnetic winding mounted in the guide groove, positions sensors and a controller, wherein the guide groove is embedded in the sidewall by 10 to 30 cm; the electromagnetic winding is 3 to 6 cm thick; the guide groove is engaged with a guide rail fixed on the sidewall of a car, and a magnetic winding is also arranged on the guide rail; the position sensors are arranged in the central positions of the sidewalls of all floors and used for outputting the position signals of the car; the controller is connected to the position sensors, and is used for receiving the position signals of the car and outputs control signals to the electromagnetic windings via a D / A (Digital-to-Analogue) converter and a current regulator.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a reluctance hoistway. Background technique [0002] The size of the elevator shaft is determined according to the selection of the elevator. The elevator track and counterweight track are installed on the shaft wall, and the reserved door opening is installed with the elevator door. There is an elevator machine room at the top of the hoistway. [0003] The elevator relies on the traction system to output and transmit power. The existing traction system is mainly composed of a traction machine, a traction wire rope, a guide wheel, and a reverse rope wheel. Therefore, the existing traction system relies on the traction force of the steel wire rope to control the lifting, acceleration and deceleration of the car body. There will be a clear sense of weightlessness during the start and stop process, and even cause dizziness to the passengers. For passengers with high blood pressure or other d...
