We describe the development of a permanent-magnet (PM) brushless DC motor for driving high-speed embroidery machines by employing advanced design and analysis techniques. In the design of the motor, magnetic field finite-element analyses accurately calculate the key motor parameters such as the air-gap flux, back electromotive force (EMF), and inductance. Using the numerical magnetic field solutions, a modified incremental energy method calculates the self and mutual inductances of the stator windings. A phasor diagram is derived to compute the motor's steady-state characteristics. To predict the dynamic performance and increase the prediction accuracy, a Simulink-based model simulates the motor performance with the real waveforms of applied phase voltage, back EMF, and current. The motor prototype tested with both a dynamometer and a high-speed embroidery machine validated the theoretical calculations.

Sewing is a labor intensive process, which is hard tokeep as part of manufacturing in high cost countries.Most of the sewing industry, including the equipmentmanufacturers have outsourced their activities to lowcost countries. The motivation for keeping these pro-cesses in high cost countries are usually the need forshort lead time in order-based production, and that thesewing process is highly integrated with the rest of thevalue chain. This is the case for a Norwegian producerof recliners, and different approaches to automate theirmanual sewing processes of leather covers for reclinershave been a major research activity the last years.
