Abstract
An electric motor for a direct drive drawworks may be supported by one or more motor mounts. The motor mounts may include adjusting assemblies adapted to increase or decrease the length of the motor mounts. The motor mounts may include damping assemblies adapted to allow damped motion between the electric motor and the surface. The length and damping coefficients of the motor mounts may be adjusted to align the electric motor with the drum or shaft to reduce vibration. The electric motor may be removable from the drawworks by, for example, a splined shaft, a flange coupled shaft, or the rotor being selectively removable from the interior of the motor.
