| Abstract |
In this work a numerical model of a synchronous motor drive for robotic applications is presented. The torque pulsations of the drive are limited by PWM current control. In this model the current reference is calculated from the emf waveform. The combined electrical and mechanical equations of the machine are solved through the operating equations of the inverter taking into account the sampling on-off control. This simulation is obtained using step-by-step numerical integration. An application on a laboratory permanent magnet synchronous motor of 6.2 kVA is done. In this paper the cases of motor acceleration and inversion of sense of rotation are treated. |
