The bruchless DC motor from Portescap is designed for hand tools. This size 12 (31.5 mm diameter) mini motor is available in 9.6V, 12V and 14.4V versions with cannulated and non-cannulated options. These motors can deliver peak torques of up to 1,720 mNm in a compact envelope.
These drives are suitable for various applications such as orthopedic drills, reciprocating saws, oscillating saws, sagittal saws, and reamers. In addition, size 12 motors can also be used in robotic surgery applications, surgical screw drivers and exoskeletons.
The brushless DC slotted miniature motors for surgical power tools are designed and manufactured using a process that encapsulates and protects stators windings and electronics from harsh external environments like autoclave and dish wash witnessed by these applications. In addition, Portescap insulates the windings per the medical safety requirements for hi-voltage protection that is mandatory for surgical powered hand tools.
Upon request, the drive systems can be coupled with autoclavable gearheads with different reduction ratios, autoclavable encoders and autoclavable controllers to meet the application needs. These drives come in different varieties to meet the divergent customer needs of reliability. Portescap motors are manufactured in an ISO/OSHA certified facility, and are RoHS compliant.
