查询词典 motor control

Description: This project shall adopt the double-mixing-shaft reciprocal rotary distribution design, with the vibration excitation/isolation system to be floating-connected by double-seated spring and hydraulic system adopting highly-dynamic performance proportion, making unnecessary a separate motor for driving and ensuring high compactness of blocks. The machine should make less noise than similar products, operate quickly, reduce the impact upon change of direction and save energy. Each joint should be linked with knuckle bearing and provided with lubricating device to prevent wear and tear. The automatic control system should use PLC and HMI display of operation, providing accurate and explicit detection of faults.
