• AC gear motor — a 120V motor with built‑in thermal protection that provides the rotational power. • Gear reduction housing — slows the motor’s RPM to create high torque. • Lead‑screw actuator — converts the motor’s rotation into straight‑line pushing or pulling force (this one is rated around 900 lb push). • Wiring harness & capacitor — provides start/run power to the motor. • Mounting bracket — holds the motor and actuator in place inside the machine. It’s essentially the component that moves something up/down or in/out under heavy load on treadmills
