Wire rope hoist frequency control mainly through the AC induction motor vector control inverter system to achieve. Electric chain hoist with belt loop speed torque, flux closed loop vector control method for electric chain hoist drive motor speed, which can be variable speed electric hoist to meet the operating characteristics of the work on the rope hoist performance and work efficiency has been greatly improved, greatly reducing the operating time of accidents and dangerous.
Frequency rope hoist system is composed of the main core driver for driving three-phase asynchronous motor, three-phase asynchronous motor is a multi-variable, nonlinear and strong coupling system.
Electric chain hoist with torque loop speed, closed-loop flux vector control system is mainly through the MCU as the master, which has a frequency generator module and high processing power. Therefore, this system is suitable for small size, embedded inverter system. Mainly applicable frequency electric hoist three-phase AC induction motors and DC machines.
