A generator can produce electricity with three required conditions: a magnetic field, a coil, and a change in flux passing through the coil. The place to put the coil on the generator is called a slot. The number of slots can affect the characteristics of the generator. Changing the number of slots affects Back EMF and KE with a fixed generator geometry dimension. The simulation uses coiled wire with a diameter of 1 mm. In this research, PMSG 12s10p was designed, and the slots were varied into 15s10p and 24s10p. The PMSG 12s10p has 12 slots with 188 coils, the 15s10p has 15 slots with 158 coils, and the 24s10p has 24 slots with 79 coils. The simulation results show that the average DC voltage on PMSG 12s10p, 15s10p and 24s10p is 256,138 V, 277,340 V and 198,299 V, respectively. Electrical constant (KE), the KE value for each PMSG variation is 2.53 (PMSG 12s10p), 2.64 (PMSG 15s10p) and 1.89 (PMSG 24s10p). The simulation results show that PMSG 15s10p produces the largest back EMF and KE values.
