14.52 × 1 = 14.52 [VA]
�
4) Brake Power Capacity (24V DC)
(2.5 + 5.8) ×1 = 8.3 [VA]
5) Motor Power Capacity
421 + 421 + 234 + 138 = 1214 [VA]
6) Motor Power Supply Heat Generation
9.12 + 9.12 + 6.12 + 3.39 = 27.75 [W]
�
7) Rated Power Capacity =
1) Control Power Capacity + 5) Motor Power Capacity = 113.62 + 1214 = 1327.62 [VA]
8) Heat Generation =
2) Heat Generation of Control System + 6) Motor Power Supply Heat Generation = 48.81
+ 27.75 = 76.56 [W]
