PM permanent magnet synchronous gearless traction machine, compact transmission structure, small size, using ultra-high precision absolute encoder, no need for deceleration system and excitation current, reduce wear, greatly reduce thermal energy, mechanical energy and other losses, maintenance more convenient; equipped with silent brake, the brake noise is smaller and more energy-saving.

The machine does not need lubricating oil, to ensure the machine room is clean, maintenance-free, and environmentally friendly.

The rotating magnetic field of the motor formed by permanent magnet materials with high temperature resistance, high density and balanced magnetic field reduces energy loss, makes the system response time fast, and improve efficiency.

Effective noise reduction of 5-10 (db)A, reducing the noise in the elevator room and the car when the elevator is running. Compared with the traditional traction system, the noise during operation can be reduced by more than 10db.

The application of dual 32-bit CPU and 32-bit high-speed digital signal processor (DSP) realizes full digital control and motor drive, which further improves the control performance and reliability of the system, and full guarantee the comfort and safety of the elevator.

The dual CPU and dual-32-bit control cabinet adopts the elevator-specific variable-voltage and variable-frequency drive control technology, which fully realizes the advantages brought by “frequency conversion” to the elevator, making the elevator operation control faster and more accurate.

Using the space vector variable transformation control technology, according to the physiological adaptation requirements of the human body, the use of computer optimization, accurate speed regulation, so as to make the operation more stable.

Through the vector closed-loop control technology, the inverter ensures that the elevator drive is strong, and the operation is stable and accurate, making the ride a real enjoyment.
