Elevator Gearless Traction Machine THY-TM-7A

THY-TM-7A gearless permanent magnet synchronous elevator traction machine complies with TSG T7007-2016, GB 7588-2003, EN 81-20:2014 Safety rules for the construction and installation of lifts-Lifts for the transport of persons and goods- Part 20: Passenger and goods passenger lifts and EN 81-50:2014 Safety rules for the construction and installation of lifts -Examinations and tests-Part 50: Design rules, calculations, examinations and tests of lift components. This type of traction machine must be used under the condition of an altitude of less than 1000 meters, and the deviation of the grid power supply voltage from the rated value is not more than ±7%. It is suitable for elevators with a load capacity of 320KG～630KG and a rated speed of 1.0～1.75m/s. Elevators are recommended. The lifting height is less than or equal to 80 meters. When this model is used for a rated load of 630kg, the balance coefficient of the elevator should not be less than 0.47; when used for a rated load of not more than 450kg, the brake current is 2×0.84A; when the rated load is greater than 450kg, the brake current is 2× 1.1A. The company has a variety of encoders, customers can choose according to their own control system. It is suitable for elevators with machine room and elevators with machine room. The traction machine of elevator with machine room is equipped with a cranking device, and the traction machine of elevator without machine room is equipped with a 4-meter-long remote manual brake release device. The installation site of the traction machine must have a dedicated grounding terminal. For safety, the motor must be grounded correctly and reliably. The 7A series permanent magnet synchronous elevator traction machine brake adopts a new safer and more reliable square brake. The corresponding brake model is FZD10, which has a high cost performance. In order to ensure that the brake can work at a lower temperature rise, it is recommended that the customer use the rated voltage to make the brake operate and then reduce the voltage to maintain it. The maintenance voltage should not be less than 60% of the rated voltage. The diameter of the traction wheel is generally greater than 40 times the diameter of the wire rope. In order to reduce the increase in the size of the traction machine, the reduction ratio of the reducer is increased, so its diameter should be appropriate.
