Megaflux Frameless Brushless Torque Motors Brushless thin-ring component (rotor and stator) torque motor Frameless Megaflux brushless torque motors are high performance frameless component torque motors consisting of a matched rotor and stator pair. Megaflux frameless brushless torque motors are computer-designed and optimized to provide the highest torque density brushless torque motors available. Special attention has been given to the minimization of their cogging torque to enhance their performance in precision applications. Frameless Megaflux motors are thin annular rings with large diameter-tolength ratios, designed to be integrated directly into mechanisms, effectively eliminating problems of torsional resonances due to couplings and backlash associated with gear trains. They are typically mounted directly to the driven axis, and their large open bore enables passing system electrical cabling, fluid piping or light beams through the axis center. Features & Benefits Three standard frame sizes and five non-standard sizes with stator dia. from 150 to 760 mm Continuous stall torque as high as 2020 Nm (1490 lb-ft) covers a broad range of applications Computer-optimized design maximizes torque density and performance Large through bore allows passage of air, water, or vacuum lines, optical beams, and/or electrical/signal wiring Three winding voltage designs for 48, 150, and 300 VDC Options & Accessories Custom winding designs to accommodate special voltage requirements Hall-effect sensor array for commutation signals Special-engineered mechanical configurations to meet specific application needs Application-matched brushless servo drives High torque density, thin-ring frameless brushless torque motor High continuous stall torque rating of up to 202 Nm (std.), 2020 Nm (non-std) Three winding designs: 48, 150, and 300 VDC SPECIFICATION SUMMARY Model Units MF0150 MF0210 MF0310 lb-ft 2.5-20.3 6.4-61.7 15.1-148.9 Cont.
