Do you have to propose a servo with specification:
Maximum specification
- rotation speed: ~1200(200RPM) deg/s (after 1.8*30 = 54 gear reduction ~20deg/s and we want 5deg/s according to this, v3 rotator specification)
- stall torque: 1.2Nm (after 1.8*30 = 54 gear reduction 64.5Nm)
Minimum specification
- rotation speed: ~360(60RPM) deg/s (after 1.8*30 = 54 gear reduction ~6.5deg/s and we want 5deg/s according to this, v3 rotator specification)
- stall torque: 0.48Nm (after 1.8*30 = 54 gear reduction 25.92Nm)
You can design an adapter, to mount a servo to motor mount, like dc motor flange.
