Tower crane
-- Otong tower crane servo slewing system, power consumption reduced by 30%--
The servo slewing system of the tower crane is used to control the slewing movement of the tower crane. The system uses the servo motor to replace the original three-phase asynchronous motor. Combined with the customized servo drive system, the current loop, speed loop and position loop of the bottom layer are optimized to realize the smooth start, stop and operation of the motion mechanism, and monitor the state of the motor and transmission mechanism, the system has stronger self-diagnosis and protection capabilities, higher energy density and better low-speed performance.
The energy density and efficiency of the motor are greatly improved, and the power consumption is reduced by 30%
· Smaller vibration and shock, noise and shock are almost negligible
· Better acceleration and deceleration performance, significant start-stop advantages, especially suitable for the smooth control of large inertia system
High reliability, strong environmental adaptability, the use temperature can reach -40 ℃ ~ 55 ℃, anti-vibration performance can reach 8g acceleration
