Magnets used in elevator motors or traction motors are typically high-performance neodymium magnets (NdFeB), favored for their strong magnetic properties, high energy density, and ability to maintain performance even at smaller sizes. These magnets play a critical role in the efficiency, speed, and precision of modern elevator systems, especially in gearless traction motors, which are common in high-rise buildings.
Key Roles of Magnets in Elevator Motors:
Direct Drive Systems (Gearless Motors): Many modern elevators use gearless traction motors, where neodymium magnets are placed in the rotor. These magnets generate the magnetic field necessary to interact with the stator, creating the torque needed to lift the elevator without the need for mechanical gears. This results in smoother and quieter operations, with higher energy efficiency.
High Torque and Speed Control: The strong magnetic field produced by neodymium magnets allows for high torque at low speeds, which is cruc…
