1. A system of lift control components comprising:
a 3-phase motor operable to raise a lift structure, and
a controller configured to condition single-phase electrical power from a power supply and provide conditioned 3-phase electrical power to the motor,
wherein the controller is configured to:
operate the motor to raise the lift structure at a first raising speed;
determine a load while raising the lift structure at the first raising speed;
determine a second raising speed based at least partially on the load, wherein the second raising speed is faster than the first raising speed; and
operate the motor to raise the lift structure at the second raising speed,
wherein the controller comprises a variable frequency drive and a lift controller, wherein the variable frequency drive and the lift controller are configured to operate in a feedback loop during operation of the motor to raise the lift structure at the first raising speed.
