Brushless DC motor speed controller
OSAI
The DAC family includes digital drives and brushless motors for axes motion control. The DAC and DSC drives have direct power (400V three phase) to simplify installation within the electrical cabinet to reduce cost and save space. To complete the family the DAM (Digital Axes Module) is available with a digital SERCOS connection to the numerical control. The drives' inherent noise immunity provides another advantage by significantly reducing wiring costs.
The associated DS series of motors are synchronous brushlesses with rare earth permanent magnets, and have a DC bus of 540 VCC. They provide high power with low current absorption, and improved dynamics with low losses.
