Megaflux series thin-ring torque motors available from Heason Technology

The frameless construction and space-saving form factor of the Megaflux allows the motor to be directly integrated on 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 Megaflux has been widely used in robotics, azimuth/elevation tracking devices, laser scanning systems, and machine tools.

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. The motor can also be assembled on customer supplied components or built into complete positioning actuator solutions through Heason’s motion systems design service. An example Megaflux motor may be built into an actuator which includes the Spinea TwinSpin® gearbox - a high precision/high torque trochoidal gear reduction system and integral heavy duty axial/radial bearing that provides a space-saving, single unit “bearing reducer” with an industry-leading output torque to size ratio.
