High performance applications like power steering and robotics require motor drives that produce smooth torque with very low components of cogging torque. To fulfil such demands a variety of techniques are known to reduce native cogging torque components in permanent-magnet motors. However, motor designers usually do not consider that assembly tolerances in mass-production give rise to additional cogging torque components, which are not present in the case of a perfect motor. A finite element… CONTINUE READING
