Frameless and torque motors
Rotor and stator kits built directly into the machine, removing couplings and gearing from the axis. Tell us the application and we'll specify the right product, and the parts around it, for your machine.
What we need to know to specify frameless and torque motors
These are the questions an applications engineer works through first. Approximate answers are fine: ranges narrow the options quickly, and we confirm the details with you.
- Outer diameter: Under 50 mm, 50–100 mm, 100–200 mm, Over 200 mm
- Peak torque: Under 2 Nm, 2–20 Nm, 20–200 Nm, Over 200 Nm
- Use: Robot joint, Gimbal / pan-tilt, Rotary table, Spindle
- Hollow shaft: Yes, No
We also ask about the environment (washdown, outdoor, subsea, ATEX, vacuum, shock and EMC), annual quantities and timescale, because these decide whether a standard, modified or custom design is the best fit.
