Double-stator energy-saving elevator traction machine

Abstract

The invention discloses a double-stator energy-saving elevator traction machine. The double-stator energy-saving elevator traction machine comprises a machine base with a built-in main shaft, a traction wheel and an elevator control system. One end of the main shaft extends out of the machine base, the extending end of the main shaft is sleeved with the traction wheel coaxially, and a lift car and a counterweight are suspended at the two ends of the traction wheel respectively. The portion, located inside the machine base, of the main shaft is coaxially sleeved with a rotor, the periphery of the rotor is sequentially and coaxially sleeved with a first stator, a spacer bush and a second stator in the axial direction, and the first stator and the second stator are connected with the elevator control system and can independently or simultaneously drive the rotor to operate. By the adoption of the structure, the effect of saving electric energy is remarkable, compared with a common traction machine, 30% of electric energy is saved, the inertia of the rotor is small, and the cost is low. In addition, the braking mode is diversified, and the systematic safety of the traction machine is greatly improved.

Description

technical field [0001] The invention relates to an elevator traction machine, in particular to a double-stator energy-saving elevator traction machine. Background technique [0002] With the rapid development of urban construction and economy, more and more high-rise buildings need to be equipped with high-performance elevators. At the same time, people have higher and higher requirements for the comfort of elevators. The permanent magnet synchronous gearless traction machine, which has risen rapidly in recent years, has attracted the attention of technicians in the industry due to its advantages of environmental protection, energy saving and high efficiency. Elevators using permanent magnet synchronous gearless traction machines are especially suitable for use in small machine room or machine room-less elevators because they have smoother starting and running, more stable and comfortable rides for passengers, compact structure of the host machine, compact size, and energy s...
