Are there any commercial solutions for electric rotary motors with integrated torque sensor and torque control?
I'm only aware of www.sensodrive.de which are essentially the drives used in the DLR/Kuka Light Weight Robot. But those use harmonic drives (gear ratio of 1/100, < 10 RPM). I need something with much higher RPM and lower torque range (less than 0.01 Nm resolution would be good). Up to 300-1000 RPM but no more than 5 Nm torque is required. So something with a small gear ratio or no gear at all.
