Torque ripple is an effect seen in many electric motor designs, referring to a periodic increase or decrease in output torque as the motor shaft rotates. It is measured as the difference in maximum and minimum torque over one complete revolution, generally expressed as a percentage. A common example is "cogging torque" due to slight asymmetries in the magnetic field generated by the motor windings, which causes variations in the reluctance depending on the rotor position. This effect can be reduced by careful selection of the winding layout of the motor, or through the use of realtime controls to the power delivery.

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Cogging torque of electrical motors is the torque due to the interaction between the permanent magnets of the rotor and the stator slots of a Permanent Magnet (PM) machine. It is also known as detent or 'no-current' torque. This torque is position dependent and its periodicity per revolution depends on the number of magnetic poles and the number of teeth on the stator. Cogging torque is an undesirable component for the operation of such a motor. It is especially prominent at lower speeds, with the symptom of jerkiness. Cogging torque results in torque as well as speed ripple; however, at high speed the motor moment of inertia filters out the effect of cogging torque. A summary of techniques used for reducing cogging torque: 1. Skewing stator stack or magnets. 2. Using fractional slots per pole. 3. Modulating drive current waveform. 4. Optimizing the magnet pole arc or width. Almost all the techniques used against to cogging torque also reduce the motor counter-electromotive force and so reduce the resultant running torque. A slotless and coreless permanent magnet motors does not have any cogging torque. Model railway motors usually have a 2-pole permanent magnet and 3, 5 or 7 poles on the armature to reduce cogging torque.

EMS Webinar: Minimizing cogging torque in a skewed stator BLDC motor
 
42:43
Minimizing cogging torque in a skewed stator BLDC Motor Cogging torque is a result of the interaction between the rotor magnets and stator slotting. This unwanted component of the torque introduces ripple in the output torque, poses higher stress on the machine bearing and produces vibration. There are few methods that are used to achieve cogging torque reduction. They usually compromise motor performance in some way, leading very often to reduced winding EMF.

Automatic Tuning of Field-Oriented Controllers for an Induction Motor
 
05:26
Implement and automatically tune a field-oriented control system that controls the flux and torque of a three-phase induction motor. Learn more about Field-Oriented Control: http://bit.ly/2BiB8Q5 Learn more about Motor Control Design: http://bit.ly/2BeNc4U The control system consists of four PI controllers. The rotor speed and flux controllers in the outer loop provide references to the current controllers in the inner loop using the measured rotor speed and three-phase stator current as well as the Clarke and Park transformations. The four PI controllers are tuned using the Closed-Loop PID Autotuner block in a single simulation. This block injects an excitation signal during closed-loop plant operation to estimate the plant frequency response and automatically tune the PID gains. Based on the PID outputs, a PWM Generator module is used to generate the gate control pulses for the semiconductor switches in the machine-side power inverter, such that the desired flux and torque specifications are met. The Closed-Loop PID Autotuner block is part of Simulink Control Design™ since MATLAB® R2018a and the induction motor and power converters have been modeled in Simscape Power Systems™.

A slottles motor design will have new zero torque ripple. i.e. no variation in torque over electrical cycle position. I was able to tune to an incredible +/-1 count following error at speed. Wow! Besides an increase in torque density this Infranor XtraFors Prime motor can hit incredibly high speed of up to 30krpm without filing the magnets off. I also found that they use Quantum Devices encoders that offer 1250 line SIN COS with our 4096 *4 interpolation that's 20,480,000 counts/rev... great for tracking space objects.

DIRECT TORQUE CONTROL OF INDUCTION MOTOR USING SVPWM
 
01:36
Direct torque control (DTC) is one of the most excellent control strategies of torque control in induction motor. The aim is to control effectively the torque and flux. Torque control of an induction motor (IM) based on DTC strategy will be developed and a comprehensive study will be made in this project. Direct torque control is the first technology to control the real motor control variables of torque and flux. This method makes the rotor more accurate and fast control, high dynamic speed response and simple to control. The reference value can be calculated using the flux and torque estimation and also motor parameters.With the Joint progress of the power electronics and numerical electronics it is possible today to deal with the axis control with variable speed in low power applications. With these technological projections, various command approaches have been developed by the scientific community to master in real time, the flux and the torque of the electrical machines, the direct torque control (DTC) scheme being one of the most recent steps in this direction. This scheme provides excellent properties of regulation without rotational speed feedback. In this control scheme the electromagnetic torque and stator flux magnitude are estimated with only stator voltages and currents and this estimation does not depend on motor parameters except for the stator resistance.

Genetic Algorithm and Fuzzy Adaptive PI Controller on Direct Torque Control of Induction Motor
 
33:13
In this project, a comparative study between adaptive fuzzy PI direct torque control and fuzzy GA. A novel direct torque control strategy, using genetic algorithm on-line to optimize the fuzzy PI controller, is proposed. In this approach, according to speed error and its first-time derivative, the proportional coefficient Kp and integral coefficient Ki can be on-line adjusted by fuzzy adaptive PI speed regulation, and the fuzzy logic adapter parameters are optimized by genetic algorithm to improve the self-adaptation of speed. Moreover, the second fuzzy logic controller is applied to select the voltage vector instead of the conventional hysteresis controllers. Fuzzy PI direct torque control and proposed approach show that not only the speed response, overshoot and speed steady precision have been improved, but also the torque, flux, and stator current ripples have been effectively decreased at low speed, and the robustness of the whole system has been enhanced.

Commutation Torque Ripple Reduction Strategy of ZSource Inverter Fed Brushless DC Motor
 
00:46
Commutation Torque Ripple Reduction Strategy of ZSource Inverter Fed Brushless DC Motor Based on the Z-source inverter, this paper proposes a novel commutation torque ripple reduction strategy for brushless DC motor (BLDCM). The proposed strategy employs the same modulation mode in both the normal conduction period and the commutation period, and the commutation torque ripple is reduced by regulating the shoot-through vector and active vector duty cycles. The proposed detection method acquires the end point of commutation by comparing the clamped terminal voltages with reference zero level, and the signal-noise-ratio of the detection is improved by avoiding the attenuation of the terminal voltages. Furthermore, a certain pulse width of the shoot-through vector can not only reduce the commutation torque ripple but also provide a new opportunity to detect the end point of commutation. Moreover, Z-source inverter provides the buck-boost ability for BLDCM drive system, then the dc voltage utilization can be improved, and the safety of the drive system can also be improved. In addition, this paper analyzes the terminal voltages during each vector. The experimental results verify the correctness of the theories and the effectiveness of the proposed approach.
