ELEKTRISCHE ANTRIEBE - Aufgabe (Katzfahrwerk)

Task: The trolley of a bridge crane is driven by an electric motor via a gearbox and reaches a travel speed of υ = 0.42 m/s at the motor's rated speed (n_N = 950 min⁻¹). The driven wheel of the trolley has a diameter of D = 0.2 m. The mass of the trolley including the load is m = 2.2 t. The mass of the gearbox and transmission components, as well as all losses, are to be neglected. The moment of inertia of the motor is J_M = 0.018 kgm². 1. Sketch the setup and assign the given data accordingly. 2. What motor power is required to accelerate the trolley to a speed of a = 1.5 m/s²? ``` 3. Plot the time-dependent curves of the motor's speed, torque, and power during the acceleration phase in a graph! ---------------------------------------------------------------------------------------------------------------------------------------------------------- More videos on the topic of #drive technology: 1.
