🛗 Traction Elevator: S-Curve Ride, Counterweight Balance and Regeneration (2D)

Side view of a counterweighted traction elevator on a jerk-limited S-curve ride, with the motor power drawn from or returned to the grid. Set load, floors travelled, rated speed, acceleration and jerk limits, counterweight balance and drive efficiency, and see the trip time, peak speed, the energy per trip going up and down, and where the car regenerates. Ride kinematics, trip time, energy bookkeeping and the balance point are checked numerically, with four in-page numerical checks.
