The model of the interior permanent magnet synchronous machine (IPMSM) is transformed to a new form, which can be treat as a surface permanent magnet synchronous machine (SPMSM). Based on the new model, novel methods for position estimation during standstill and low speed are presented. Carrier-signal-injection is used; high frequency, persistent, rotating current vector is injected into the plant...
