Product description
D2-02 Dievskiy
Rotating with an angular velocity ω0 = 2.5 rad / s the rotor of the electric motor
Begins to slow down by forces of aerodynamic resistance, the moment
Which M1 = 15ω, and frictional forces in bearings, the moment of which M2 = 30 N. M.
The moment of inertia of the rotor relative to the axis of rotation is J = 100 kg. M2.
Determine how long the rotor will stop.
