ThyssenKrupp Access Porch-Lift 3/4HP Motor Replacement

3/4 HP 115/230V single-phase porch lift motor designed for ThyssenKrupp Access Porch-Lift systems including PL2K and Pre-PL2K configurations.

This 3/4 horsepower electric motor is used in select ThyssenKrupp Access porch lift systems that require a NEMA 56 frame single-phase drive motor. It provides the power necessary to operate the lift drive assembly used in many residential porch lifts, delivering consistent torque and dependable performance for vertical travel.

The motor supports dual-voltage operation at 115V or 230V and operates at 1725 RPM on 60 Hz power or 1425 RPM on 50 Hz power. Its capacitor-start, induction-run design allows the motor to develop strong starting torque, which is important for lift applications where controlled movement and reliable startup are required. The open enclosure and steel frame construction support long-term durability in porch lift environments.

This motor configuration is used in several ThyssenKrupp Access Porch-Lift installations and may be installed in both PL2K and earlier pre-PL2K systems when the lift requires a 3/4 horsepower NEMA 56 frame motor. Wiring arrangements can vary depending on the controller generation used in the lift, and wiring diagrams for both PL2K and earlier porch lift systems are provided for installation and replacement.
