It has a compact structure and complete functions.It integrates traction motor, traction wheel, electromagnetic brake and photoelectric encoder.It is easy to install and use.
Especially in the development and application of machine roomless elevators, a permanent magnet synchronous traction motor is installed in the elevator shaft, which not only saves the construction cost of the machine room, but also beautifies the appearance of the building.
When the elevator load changes, the permanent magnet synchronous motor adapts by adjusting the angle, and its response speed is very fast.
In order to make the elevator have good starting, braking comfort and horizontal accuracy, accurate rotor position equipment and voltage and current detection equipment are added to the system to determine the size and direction of the motor magnetic field at any time. The position detection equipment uses a rotor position sensor photoelectric encoder or resolver.
The car load detection device can use various forms such as position type and pressure type to perform pre-measurement and calculation of elevator load, give torque in appropriate direction and magnitude, and can output higher switching value, analog voltage and frequency Frequency anti-interferenceStrong and can be transmitted over long distances.
Its advantages mainly include the following points: simple and compact structure, low maintenance; high safety and reliability; low noise to the environment, no grease pollution, can improve the power factor of the power, is an ideal environmental protection product; improve the efficiency of mechanical transmission, Energy saving, economical, and high cost performance; no gears for communicationInduction motorCompared with the drive system, the asynchronous motor has the advantages of unparalleled low speed, fast speed, hard mechanical characteristics and automatic shutdown when stopping.Compared with DC gearless motor drive, compared with this system,Permanent magnet synchronous motorIt has the advantages of higher low-speed performance, speed regulation accuracy, fast response speed, long life, low power consumption, and simple maintenance.In addition, for low-speed and high-torque elevators, it is easy to achieve an ideal drive model.
