Elevator shaft

Load, direction, balancing factor and roping: the motor torque, its sign and the quadrant.

Try it: counterweight, roping and the quadrant

Load in the car1,000 kg

Balancing factor B0.50

Quadrant I: motoring, energy from the grid

The car side is heavier by 500 kg.

T = ΔM · g · D / (2 i) ÷ η

Divide by η when motoring, multiply by η when generating: friction helps to brake.
