1. Calculation formula:(1)PIN=P1Xf(No more than 20 starts and stops per hour)
(2)PIN=1.2XP1Xf(21~60 starts and stops per hour)
(1)PIN≤PN
The molding power must be less than or equal to the allowable power
In the formula: PIN is the selected power, P1 is the actual required power, f is the usage factor, PN is the allowable power.
Model selection
1. Model calculation formula: (1) PIN = P1Xf (the number of starts and stops per hour is not more than 20 times/hour)
(2) PIN = 1.2XP1Xf (number of starts and stops per hour: 21 to 60 times/hour)
(1) PIN ≤ PN
Modeling power must be less than or equal to the allowable power
Where: PIN is the selected power, P1 is the actual required power, f is the usage factor, and PN is the allowable power.
Use factor f
Thermal power calibration
1. Thermal power calculation: PGN = PGXf1 × f2
PGN>P1(natural cooling)
PGN<P1(Fan or cooling)
In the formula: f1 is the ambient temperature coefficient, f2 is the continuous working coefficient, PG is the commutator heat capacity, P1 is the actual power required for work, and PGN is the commutator calculated heat capacity.
2. Ambient temperature coefficient f1
3. Continuous working coefficient f2
Heat capacity PG (natural cooling)
