Purpose: The aim of this paper is to optimize the input current so that it reaches the requested velocity-position condition with the lowest amount of misaligned magnetic field and current converted to heat. Design/methodology/approach: A new control method based on open architecture is introduced. Then the enhanced free running of pulse width modulated (PWM) driver is represented. Findings: The actual requested motor current is reached. Practical implications: The result of this dynamic control method is represented on CNC two axes cutting machine and extended to the other systems. Originality/value: 1. Execution simple and powerful algorithms with sufficient accuracy and speed and also manufacturing a sample one. 2. The current is being controlled by data output of positioning sensors. 3. Regarding to database updating of resistance force versus to the distance of each axis, it is possible to define a periodic control method to determine resistance forces of suspension CNC systems. 4. Reduction in speed error and also increasing in machined surface quality via analysis of linear speed’s error in a system of two axes which are executed by free-running PWM driver circuit with constant and variable reference voltages. 5. Increasing in working efficiency, decreasing in energy loss and long lasting of motor drives.
