Servomotors handle high torques
The motor can be directly integrated on the driven shaft, eliminating the resonance associated with flexible couplings.
Heason Technology has released brushless servomotors with a separate rotor and stator design They provide smooth, precise control and direct drive of large-inertia or high-torque loads

Need to position precisiely in high vacuum?
Precision linear motion systems for ultra high vacuum conditions (UHV) have been introduced by Heason Technologies Group.
The Megaflux thin-ring torque motor from Emoteq has a large diameter-to-length ratio - from 150 x 30 to 760 x 123mm, and covers continuous stall torque from 3 to over 2000nm.
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.
With no need for a gearbox, the high-torque/low-cog output is backlash-free, ensuring precise control.
The large through-hole is useful for accommodating electrical wiring and services such as slip ring assemblies and beam delivery systems, while 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 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 a high output torque to size ratio.
