Variable speed drives regulate the operation of electric motors, and save energy by matching the output of motor-driven pumps, fans, conveyors and similar equipment, with the actual demand of the systems they support.
Companies could conceivably cut their energy bills associated with running, for example, their air-conditioning system, by 90 percent by installing variable speed drives.
HITACHI, BTL Industrial Ltd’s partner for inverters, developed inverters under special consideration of network abilities and international standards, such as CE and UL. Such innovative inverter components as the ISPM module, Advanced Sensorless Vector Control and state-of-the-art Fieldbus technology, make Hitachi inverters a popular choice for all drives and drive systems.
The new SJ300 Inverters are among the most powerful of their class. Hitachi‘s unique “Advanced Sensorless Vector Control” (ASLV; patent pending) offers 200% starting torque and full torque at zero Hz – without feedback. The integrated Hitachi 32-bit SuperH RISC processor delivers the dynamic response needed for high-end applications. To compensate possible temperature fluctuations within the motor, which might adversely affect smooth control of the motor, an online/offline motor-auto-tuning function is included. A newly developed internal control process leads to drastically reduce any rotational fluctuation at low speed, which enhances process stability and precision.
The SJ200 is a true muscle-man, featuring enhanced ISPM-technology with vector control. Outstanding performance and design characteristics, such as superior torque for demanding applications and exceptionally compact size, for SJ200 inverter in a class of their own. They are suited for various applications in textile, paper and printing industries as well as for all areas of the metalworking industry, cranes and elevators.
