Motor power calculation of trolley drive (Indoor EOC)

* Motor power calculation of trolley drive (Indoor EOC)

 

* Trolley drive(traversing) speed(min) : V = m/min

* Trolley drive(traversing) speed(sec) : Vs = m/sec

* Rated load : R = ton

* Hook(attachment) weight : A = ton

* Trolley self weight : T = ton

(trolley frame & trolley drive & hoisting device & acc.)

* Trolley wheel dia. : Dw = cm

* Trolley wheel shaft dia. : Ds = cm

* Mechanical efficiency : Em = (Refer to wheel bearing)

* Journal friction coefficient : µ =

* Additional resistance bearing : a =

* Acceleration time : ta = sec

* GD2 ratio (total GD2 / linear moving part GD2) : ß =

* Used motor power : Pu =     kw x    set

 

* Trolley wheel resistance

 

* Running power

 

 

* Acceleration power

 

* Required motor power
