Heason Technology is now supplying a range of brushless servo motors with a separate rotor and stator design for the smooth, precise control and direct-drive of large inertia or high torque loads. The Megaflux thin-ring torque motor from US manufacturer, Emoteq Corporation has an inherently large diameter-to-length ratio - from 150 mm x 30 mm to 760 mm x 123 mm – and covers continuous stall torque from 3Nm to more than 2,000Nm.
The frameless construction and space-saving form factor of the Megaflux allows the motor to be directly connected to the driven shaft eliminating the resonance associated with flexible couplings; and with no need for a gearbox, the high torque/low cog output is backlash-free ensuring precise control.
The large through-hole is especially useful for accommodating electrical wiring and other services such as slip ring assemblies and beam delivery systems ,whilst the form factor will suit OEMs requiring rotary positioning axes in space restricted applications.
The standard range covers eight frame sizes and forty models with motor characteristics fully specified in a 24 page catalogue available in hard copy of as a PDF from Heason Technology. In addition, customised windings are available to optimise the applications’ torque and speed performance requirements. Hall sensors can also be built into the assembly, simplifying commutation.
Heason can supply the Megaflux thin-ring motor as a separate component along with commutation and positioning encoders, servo drives and motion controls. Heason can also mount the motor on customer supplied components or build it into positioning actuation systems.
