The ETC motor drive system consists of two parts: a dedicated servo drive and a servo motor. This series of motors consists of a permanent magnet servo AC motor, a high-quality aluminum alloy extruded frame and a well-designed gear reducer. It has high power density, low noise and vibration, high efficiency and is driven by a proprietary drive. The response time is fast, and has obvious advantages compared with the traditional three-phase asynchronous motor of the same power level. It has high efficiency, high power factor, good capability index, small volume, light weight, low temperature rise, and remarkable energy saving effect. The ground has improved the quality factor of the power grid, fully utilized the capacity of the existing power grid, and saved the investment of the power grid. The motor drive uses a servo motion control algorithm to accurately position the switch door position and motion curve through the encoder, and integrates the PLC function. It has the advantages of quick lifting and stable movement, and can be used in highway toll stations, industrial and mining enterprises, military, hospitals, hotels and supermarkets.
