Questions & Answers
Answered by TorqDrive team within 2 hours
QCan I use this gearbox with a non-IEC motor?
A: TorqDrive TRV Series gearboxes are designed for standard IEC B5/B14 flanges. For non-IEC motors, you would need an adaptor plate. Contact us with your motor's flange dimensions and we'll advise.
QWhat is the maximum radial load on the output shaft?
A: Maximum radial load depends on the frame size and ratio. For exact values, refer to our technical catalogue (downloadable from the footer). Generally NMRV 63 = 6,270 N, NMRV 90 = 8,180 N.
QCan I get a custom output shaft configuration?
A: Our standard TRV Series is hollow shaft with keyway. For solid shaft, double shaft, or torque arm configurations, please contact us — we can source or adapt.
