A range of brushless slotless Ultra EC motors
demanding tasks at speeds up to 30,000 rpm and deliver a continuous torque of approximately 133.137nMm . Constructed with sturdy stainless steel combined with a lightweight aluminium flange , they provide essential durability for surgical applications .
The integrated Hall sensors offer vital real-time feedback , ensuring unparalleled precision where there ’ s no margin for error . It ’ s patented “ U-Coil ” technology provides up to 30 % more torque than similar-sized motors with conventional coils , operating cooler and more efficiently . Highlighting their adaptability for medical settings , while many motors can withstand up to 1,000 autoclave cycles , the Ultra EC range endures over 3,000 ensuring consistent sterility . conserves space , enabling a compact size and agility without sacrificing on power or precision .
Another distinct advantage of slotless BLDC is their immunity to cogging . There are no iron-core windings to attract the interior magnets , which translates to better precision , consistent force and a broader dynamic range – qualities that are indispensable for surgical procedures .
Slotless BLDC motors also have the advantage of operating more efficiently with minimal heat generation due to the absence of iron-core windings . This ensures that the surgical area remains stable , without disruptive temperature fluctuations , ensuring the patient ’ s safety during the procedure and minimising heat-related damage of the robot ’ s components .
