A direct drive drawworks (100) has a permanent magnet motor (40), a shaft (41) extending from the permanent magnet motor (40) so that the permanent magnet motor directly rotates the shaft (41), and a drum (43) connected to the shaft (41) away from the permanent magnet motor (40) such that the rotation of the shaft causes a corresponding rotation of the drum. The permanent magnet motor (40) has a housing (42), a stator (62) positioned in the housing, and a rotor (64) cooperative with the stator. The rotor (64) has a drive plate (66) affixed thereto. The shaft (41) is directly connected to the drive plate (66). A bearing housing (45) rotatably supports the shaft.
