Technical Structure of Gearless Motors:

This post is also available in: العربية (Arabic) فارسی (Persian)

Gearless motors are typically synchronous or induction motors that are directly connected to the elevator’s drive system. These motors use a powerful magnetic system to ensure smooth and precise movement of the elevator car. The main components of these motors include:

Stator:
The stationary part of the motor, consisting of electrical windings that create a magnetic field to rotate the rotor.

Rotor:
The rotating part of the motor, usually made of permanent magnets. These magnets interact with the stator’s magnetic field to produce motion.

Control System (Drive System):
This includes the inverter and electronic systems that precisely control the motor’s speed and torque.

Safety Brake:
An electromechanical braking system that activates in emergencies or when the elevator stops.

Bearings:
High-quality bearings are used to reduce friction and increase the motor’s lifespan.

Advantages of Fuji Gearless Motors:

1. High Energy Efficiency:
   Gearless motors, due to the absence of a gearbox and mechanical friction, have higher energy efficiency (typically over 90%). This reduces electricity consumption and operational costs.
2. High Speed and Precision:
   These motors can achieve very high speeds (up to 10 meters per second or more) and ensure smooth and precise movement of the elevator car.
3. Low Noise and Vibration:
   The absence of a gearbox and the use of permanent magnets result in minimal noise and vibration.
4. Compact Design:
   Gearless motors occupy less space in the machine room, making them ideal for buildings with space constraints.
5. Long Lifespan and Low Maintenance:
   With fewer mechanical parts, gearless motors require less maintenance and have a longer lifespan.
6. Compatibility with Smart Control Systems:
   These motors are easily compatible with advanced and intelligent elevator control systems, allowing for precise management of elevator performance.

Disadvantages of Gearless Motors:

1. Higher Initial Cost:
   Gearless motors are more expensive initially due to the use of advanced technology and permanent magnets.
2. Technical Complexity:
   These motors require more expertise for installation and maintenance due to their advanced electronic systems.

Applications of Fujihd Gearless Motors:

• High-Speed Elevators:
  For tall buildings such as office towers, hotels, and commercial centers.
• Passenger Elevators:
  In residential and office buildings where smooth and quiet operation is required.
• Luxury Elevators:
  For projects that demand advanced design and flawless performance.
• Hospital Elevators:
  Ideal for transporting patients and medical equipment due to their smooth and quiet operation.

Comparison Between Gearless and Geared Motors:

Conclusion:

Fujihd’s gearless motors, as one of the most advanced elevator motors, offer high energy efficiency, high speed, and smooth operation, making them an ideal choice for modern and high-rise buildings. Although the initial cost of these motors is higher, they are more cost-effective in the long run due to reduced energy and maintenance costs.
