Traction machines require acceleration and deceleration control that generates high levels of torque in order to move ultra high-speed, large-capacity elevators, which means that basic technology providing raw power is indispensible.
Hitachi uses PM motors (permanent magnetic synchronous motors) that are compact yet provide high output.
We have also incorporated the new technologies listed below within the control panels in order to cope with this large-capacity output.
These technologies will provide the cornerstone for the development of elevators into the future.
