Elevator Gearless Traction Machine THY-TM-9S

THY-TM-9S gearless permanent magnet synchronous elevator traction machine complies with the relevant regulations of TSG T7007-2016, GB 7588-2003, EN 81-20:2014 and EN 81-50:2014 standards. This traction machine needs to be used in an environment where the altitude does not exceed 1000 meters. The air temperature should be kept between +5℃～+40℃. It is suitable for elevators with a load capacity of 630KG～1150KG and a rated speed of 1.0～2.0m/s. It is recommended that the lifting height of the elevator is ≤80 meters. The company is equipped with sine-cosine encoder HEIDENHAIN ERN1387, which can be applied to machine room elevators and machine room-less elevators. The machine room elevator traction machine is equipped with a hand wheel, and the machine room-less elevator traction machine is equipped with a remote brake release device and a 4m brake line. Due to the use of high-frequency inverters for power supply, low-voltage induced electricity may be induced on the casing of the permanent magnet synchronous traction machine. Therefore, it must be ensured that the traction machine is correctly and reliably grounded during the power-on operation of the traction machine. The 9S series permanent magnet synchronous elevator traction machine brake adopts a new safer and more reliable square brake. The corresponding brake model is FZD12A, which has a high cost performance. The traction sheave is the sheave on the traction machine. It is a device for the elevator to transmit traction power. The friction force between the traction wire rope and the rope groove on the traction sheave is used to transmit power. It must bear the car, load, counterweight, etc Therefore, the traction wheel is required to have high strength, good toughness, wear resistance, and impact resistance. Ductile iron is often used as the material.
