Disclosed is a laundry treating apparatus including a tub for providing therein a space for water to be stored, a drum rotatably disposed inside the tub and providing therein a space for clothes to be stored, wherein the drum includes an open surface for inserting and withdrawing the clothes therethrough and a bottom surface located on an opposite side of the open surface, a pulsator rotatably disposed on the bottom surface and inside the drum, an agitator protruding from the pulsator inside the drum and extending toward the open surface, wherein the agitator is rotatably disposed at a center of the pulsator, and a driver configured to drive at least one of the drum, the pulsator, and the agitator. The pulsator and the agitator may be configured to rotate in opposite directions.

A pulley has a plastic body having a peripheral seat and a central hub defining a through opening, with teeth extending from the central hub into the through opening. A metal insert is located within the hub and has at least a portion circumscribing the through opening.

A washing machine appliance or drive assembly, as provided herein, may include an agitator drive shaft, a stationary housing, and a motor. The agitator drive shaft may extend along a drive axis. The stationary housing may be disposed about the agitator drive shaft. The motor may be operably connected to the agitator drive shaft to drive rotation thereof. The motor may include a rotor, a stator, a support bushing, and a linear fastener. The rotor may be fixed to the agitator drive shaft. The stator may be rotationally positioned radially inward from the rotor. The support bushing may be ultrasonically welded within the stator. The linear fastener may extend through the fastener to the stationary housing.
