The sewing process is a manufacturing technology which presents severe challenges for automation. Due to variations in the material properties and unpredictable mechanical compliance, real-time sensor-based control strategies are necessary to achieve satisfying results. This paper presents a sewing cell consisting of two lightweight industrial robots and a sewing machine. Sensors are included both for force and edge positioning control. Experiments are presented showing the performance of the proposed real-time control framework. The experiments focus on the real-time control loop for force and edge control during the sewing process.
llustrates the magnetically relevant parts of the motorprototype. The laminated stator has 12 slots, in which the three-phase single-layer windings are placed. The rotor core and shaftare made of solid mild steel, and four pieces of NdFeB PMs aremounted and bound on the surface of the rotor. The stator corehas an inner diameter of 38 mm, outer diameter of 76 mm, andaxial length of 38 mm. The main air-gap length and the heightof PMs along the radial magnetization direction are chosen as 1and 2.5 mm, respectively. The motor is designed to deliver anoutput torque of 1.0 Nm at a speed of not less than 5000 r/min
Magnetic field FEA can take into account the detailed struc-ture and dimensions of the motor and the nonlinearity of fer-romagnetic materials, and hence can accurately compute themotor parameters and performance [9]. Fig. 2 illustrates themagnetic field distribution at no-load at the rotor position shownin Fig. 1, from which the phase winding flux produced by therotor PMs, back EMF, and cogging torque can be determined.The curves of these parameters against the rotor angular posi-tion or time can be obtained by a series of magnetic field FEAs atdifferent rotor positions.
