[FEMM] [cogging torque problem???]



Dear everyone,

 

 My name is Kang in South Korea. I designed a BLDC motor 5 days ago. For the analysis of cogging torque , I am using FEMM and LUA.

 In my process, there is a problem. Cogging result is unusual and very spiky. I want to know its reason and solution.(Why???) Could any one help me please?
