The attached script provides some examples of typical space vector PWM functions. Individual schemes can be plotted, showing the modulation function, neutral voltage, and line-to-line voltages. The script plots various space vector modulation f...

System and circuit modelling has long been an important aspect of motor control system design. With a Model-Based Design (MBD) approach, electrical, mechanical and system-level models are used to evaluate design concepts before building and testing...

Optical, magnetic and capacitive technologies are widely used for signal isolation in industrial motor control applications. Digital isolators based on magnetic (transmission by transformer) methods have for the last decade provided a viable and of...

Die Implementierung eines Σ/Δ-Modulators verlangt einen digitalen Filter im Antriebssteuerungssystem. Dieser wird i.d.R. mit einem FPGA oder einem ASIC implementiert. Wegen der höheren Systemkomplexität im digitalen Bereich und dem FPGA galt diese ...

This webcast examines the considerations and challenges at key isolation nodes within the motor control signal chain. Choice of an isolation architecture can greatly affect the final system architecture complexity and cost. The isolation required b...

With motors consuming upwards of 40 per cent of worldwide energy, measurement techniques for industrial motion control are becoming increasingly important. This article by Nicola O'Byrne (NicolaOB) in Components in Electronics magazine addresses in...

Industrial motion control covers a breadth of applications, ranging from inverter-based fan or pump control, to factory automation with more complex ac drive control, to advanced automation applications such as robotics with sophisticated servo con...

Isolation is an integral part of ac voltage motor drives. There are several methods of providing electrical isolation— primarily, optocouplers and digital isolators are used. The use of digital isolators provides several benefits as compared to tra...

Industrial motion control systems require sensing and feedback of a number of variables such as motor winding current and voltage, dc bus voltage and current, and motor position and velocity. The measurement technology, measurement variables, and p...
