Large high Torque motor

MI-F-485 mm - Direct Drive

Magnetic Innovations’ large high torque motor MI-F-485 mm (~19 inch) uses direct drive technology which enhances its dynamic performance while it reduces costs compared to conventional solutions. Moreover, it is a frameless motor – so, a motor without a frame, housing, bearing or feedback system – which results in the possibility to optimize the motor according to your own needs. 
Our large high torque motor eliminates limitations such as backlash, cogging, and long-time drift due to very high control loop bandwidth and direct coupling. Moreover, the motor is very suitable for applications where noise needs to be reduced, as it does not use gearboxes, belts, or other transmissions. In other words, the direct drive MI-F-485 mm assures a quiet operation, high efficiency, and longer life expectancy.
