Patented technology in Allied Motion's PerformeX series miniature slotless brushless DC motors enables them to deliver up to double the performance of equivalently-sized motors. The PerformeX series was designed specifically to power precision instruments such as surgical handpieces and similar medical and dental power tools; however, they are also an ideal choice for any application that requires a small yet powerful, high speed BLDC motor, such as small high speed spindles, machine automation, or robotics. Features & Benefits Sizes 5 and 6 (12.5 and 15.24 mm) diameter accommodate a wide range of surgical handpiece designs Standard 24 and 48 VDC windings High speed capability up to 75,000 RPM High Km values mean high torque density and high performance Slotless design for smooth cog-free torque output Precision ball bearings for long life and low audible noise Hall-effect feedback as standard Options Planetary gearhead (5:1, 10:1, 25:1) Autoclavable version (minimum of 500 autoclave cycles) Shaft seals Custom winding designs Custom shaft, cabling, materials designs

Size 5 (0.5" dia.) and size 6 (0.6" dia.) high performance brushless DC motors for surgical handpieces Double the performance of same sized competitive units Available options include planetary gearhead and autoclavability
