NovaDriveTM 400

NovaGenTM 400

Oil-less Drive Train

These oil-less drive trains offer high performance without a gearbox at rotational speeds up to 20,000 rpm. The NovaDriveTM motors and NovaGenTM generators use permanent magnet rotors supported on magnetic bearings to achieve increased efficiency and high torque density. To simplify integration into a system, the control electronics for the magnetic bearings are seamlessly incorporated into the drive train, greatly reducing the field wiring. These design innovations decrease the size and complexity, improve the dynamic performance, and increase the economic value of the system.
