Structure of a multi-phase industrial servo drive with highly integrated inverter

Inhalt:
Novel actuator designs are enabled by multi-phase 1 (1 more than three phases), permanent-magnet synchronous machines with power semiconductors placed directly at each tooth coil. With this concept it is possible to realize space and cost-saving drives for industrial use. In these drives many parts can be used several times to generate economic benefit. Due to the multi-phase structure the base field utilization can be increased. Furthermore the multi-phase machine with no star connection gives additional degrees of freedom for the machine control strategy. This report is based on the project EMiLE, which is funded by the German Federal Ministry of Education and Research under promotional reference number 16EMO0007.
