FAQ
What does “7-inch” mean on SC7?
It refers to the slewing-drive size class. SC7 offers higher tilting and holding capacity than SC3/SC5 for larger single-axis applications.
Can SC7 be used on solar trackers?
Yes. Output torque, holding torque, tilting moment and ≤0.17° precision suit many single-axis PV tracker designs — confirm panel area and wind load first.
Does SC7 include motor feedback?
Yes. The 24VDC motor includes a magnetic pulse generator with Hall A/B quadrature signals for position feedback.
Can mounting and cables be customized?
Yes. Flange interfaces, motor packages, cable length and feedback options can be reviewed against your mechanical layout.
