“…Generally, magnetic saturation is reported as an effect that breaks the assumption of linear magnets. The saturation occurs when motors are forced to produce high instantaneous torque at overload conditions (Kerdsup and Fuengwarodsakul, 2011; Sullivan and Sanders, 1992). In the operation of this device, injected cells are gentle and the motor operates under rated conditions, so there is no concern about the presence of saturation in the magnetic circuit.…”

This paper presents a novel measurement method for angular displacement of an oscillation-assisted micro drill device, Ros-Drill©. The device is driven with a brushless dc motor (BLDC) which is desired to track a sinusoidal position reference. The measurement method is based on the principle of monitoring the back-emf voltage that is induced on the non-fed winding of the brushless motor. It offers sensorless analog measurement of the angular displacement of the oscillatory motion which is not possible with optical encoders. The measurement methodology and control algorithms are implemented utilizing a digital signal processor. Experiments reveal that the method is feasible for measuring angular displacements of rotational oscillations during cellular piercing operations. Furthermore, it presents fair performance for frequencies up to 1000 Hz and provides early diagnosis for a potential malfunction of the micro drill.

“…To make synchronous between back emf's and stator currents, the last have to be quasi-square shape to produce high torque and steady speed. The six-step strategy is the known operation for stator that makes two phases on and the third is float [4][5][6].…”

“…Different speed control techniques are proposed and implemented to achieve an accurate torque rate and speed control behavior. The control used in most research depends on the PID controller in which its parameters are tuned either by trial and error, Ziegler-Nicholas, a fuzzy optimization technique, genetic or particle swarm optimization [5][6][7]. Advanced techniques to improve the operation of the PID controller are also interested such as employing fractional-order PID-Controller and using this controller via two order of freedom [8][9][10].…”

The brushless DC (BLDC) motor is a multi-variable and non-linear system so that it's required more advanced explaining and controlling set. In this work, an algorithm is proposed based on the harmony search algorithm (HAS) method. HSA mimics music improvisation process to find the optimal solution. In BLDC motor, many constraints are required; speed performance and current limiting control are dominated. HAS is proposed to find the optimal PID parameters for the two speed and current-limiting controllers that are proposed in the drive. By Matlab/Simulink results, a good performance is shown compared with the classical method that absence current-limiting controller.

“…The stator current must be semi-square in order to synchronize with b-emfs to make stable and higher torque at steady speed. The operation of this motor is done when two phases are ON state and the third is floating for every 60 electrical degrees [4][5][6].…”

As a result of increasing the use of the brushless direct current (BLDC) motor in many life applications instead of the traditional motors, it is important to list and specify the more for its controlling methods. This paper presents a number of speed and current controlling methods as hysteresis band, variable dc-link bus voltage and pulse width modulation (PWM) controlling methods. These controlling methods have proportional integral derivative (PID) gains which are optimized by using particle swarm optimization (PSO) algorithm. By using fast Fourier transform (FFT) analysis to study the controller behavior from frequency analysis of the output signals and compute total harmonic distortion (THD), it can specify the more useful controlling method. The framework is modeled and fabricated by using Matlab/Simulink.
