Abstract

Embodiments herein relate to a permanent magnet (PM) motor driven hoist system. The hoist system includes a PM out-runner motor (130) with a stator (150) on a fixed central shaft (131) with stator coils (156), and an outer rotor assembly (160) coaxial with and rotatable about the stator (150). The rotor having a rotating housing (132) with an outer surface radially outward of the shaft (131) and an inner surface radially inward of the shaft (131) and plurality of PMs (162) disposed at the inner surface configured to magnetically couple with the stator (150). The rotating housing (132) coupled to the cable drum (180) such that rotation of the rotor assembly causes rotation of the cable drum (180). The system also includes a controller (120) connected to a power source and the motor, configured to generate excitation signals applied to the stator coils (156) to induce a torque in the outer rotor assembly (160) and cause it to rotate about the stator (150) and central shaft (131).
