Our product, the hoist motor, is a synchronous gearless motor using permanent magnets, designed to replace traditional geared motors for elevator operation. This motor features a gearless structure, which reduces size, eliminates friction, and improves energy efficiency, while significantly reducing noise and vibration.
The hoist motor serves as the heart of the elevator, responsible for lifting and lowering. By removing the traditional gearbox, this advanced gearless technology increases efficiency by 150% and reduces electricity costs by 40%.
Elevator hoist motors are generally classified into two types: geared and gearless. The gearless type eliminates the need for a gearbox, directly connecting the motor shaft to the pulley. This simplifies the system by removing complex gear mechanisms such as worm or helical reducers, which are typically used to convert high motor speeds into torque. As a result, energy loss is minimized, noise is reduced, and maintenance becomes simpler, as there is no need for regular oil changes or gear replacements that can affect ride comfort. Although periodic greasing of bearings is still required, it can be easily managed during routine inspections.
In contrast, geared systems require significant downtime for oil changes and refills, rendering the elevator unusable during maintenance. Due to its numerous advantages, our gearless motors are increasingly used not only in passenger elevators but also in freight elevators. Furthermore, it is expected that gearless motors will become more widespread globally in high-speed, high-load elevators.
