Transmission Designs
Magnum JRM Transmission
Magnum Drilling Solutions has developed a robust and inexpensive transmission technology that is utilized and interchangeable to all motor product lines.
This technology is a trade secret of Magnum and all IP and manufacturing rights are proprietary.
License agreement for the sale and manufacture of the transmission is available.
Quick Overview
• Utilizing a Spline as the anti-rotation mechanism, this transmission eliminates complexity and cost.
• 52 points of contact reduce backlash and maintain consistent high torque transfer mechanism
• Both flex shaft and CV styles are utilized depending on the application
• Flex shaft for High Torque Premium Power Applications (Spline direct to Rotor)
• CV for conventional and shortened transmission applications (Spline By Spline)
