bwin开户_bwin娱乐qt_必赢bwin官方     Product overview MOTOR C0NTROLIER series motor energy-saving equipment product is a new generation motor energy-saving control product. It applies digital control technology based on micro-processor and built-in dedicated energy-saving optimization control software to regulate the voltage and current of the motor operation dynamically. Without changing motor speed, it ensures that the motor output torque exactly matches the loading requirement, so that the energy waste caused by motor excessively apply work is effectively avoided with prominent power-saving feature. Meanwhile, with perfect soft startup and soft stop functions, MOTOR C0NTROLIER can ensure motor continuous and smooth startup, eliminating the mechanical shock and large startup current caused by normal motor startup, effectively reducing wear of bearing and belt, generally reducing the mechanical stress of the chain and gear, so that it extends the motor life-cycle.   Basic principle Actually, few motors are always operating at rated condition. Generally, the rated power of the selected standard motor is higher than the maximum requirement of driving load. For this reason, the selected motor is generally beyond the standard. When providing rated voltage, even at full load operation, there is energy-saving space. Although the maximum load is intermittent and the load is much lower in other time, the loads of some applications are always changing, and the selected motor should be able to meet the requirement of maximum loading operation. As the torque generated by motor is proportional to the square of supply voltage, reducing terminal voltage will cause torque decreasing. Actually, reducing terminal voltage is to reduce motor rated output power, meaning that the required magnetic energy is reduced. With this principle, MOTOR C0NTROLIER can keep constant motor efficiency under several conditions.   Field of application MOTOR C0NTROLIER can be applied for energy-saving control of asynchronous induction motor. It can be widely applied in various power equipments and processing machinery and the energy-saving effect is more significant for the motors, which operates in continuous changing load condition or is not always operating at full load with constant velocity. Such as stamper, machine tool, milling machine, grinding machine, metal grinding machines, and other metal processing machines; plastic product industry, including granulator, injection moulding machine and others; textile industry, including cheese machine, weaving machine, rotary machines and so on; and other equipments, including transmission equipment, compressors, escalator, elevator, air condition with constant temperature and humidity, vacuum pump and others.
