摘要：

Cogging torque of brushless permanent magnet (PM) motors employing segmented stator cores with narrow slot opening has been investigated. Two types of test motors were examined: one With a segmented Halbach cylinder rotor and the other with a radially oriented ring PM rotor. The measured togging torque was predicted from the measured dimensional errors for the inner radius of the stator core in both types.
