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. 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.

More information at: http://modlabupenn.org/anticogging/ Low cost brushless direct current motors are becoming more prevalent, especially from the hobby remote control community. These motors often have the required high-torque density; however, they also have significant torque ripple. This video and accompanying paper presents a low cost method for anticogging, the compensation of 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.

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.

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.

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.

Commutation Torque Ripple Reduction in BLDC Motor Using Modified SEPIC Converter and Three level NPC
 
00:21
This paper presents a new power converter topology to suppress the torque ripple due to the phase current commutation of a brushless DC motor (BLDCM) drive system. A combination of a 3-level diode clamped multilevel inverter (3-level DCMLI), a modified single-ended primary-inductor converter (SEPIC), and a dc-bus voltage selector circuit are employed in the proposed torque ripple suppression circuit. For efficient suppression of torque pulsation, the dc-bus voltage selector circuit is used to apply the regulated dc-bus voltage from the modified SEPIC converter during the commutation interval. In order to further mitigate the torque ripple pulsation, the 3-level DCMLI is used in the proposed circuit. Finally, simulation and experimental results show that the proposed topology is an attractive option to reduce the commutation torque ripple significantly at low and high speed applications.

Note the slop in the armature that will cause the RPM readings to vary do to torque ripple in the housing. with proper bearings etc. This motor should produce a 3600 RPM to run a generator. The. HP = Torque X 5252 / RPM. The rotating housing weighs 14 pounds with magnets inside which adds to the momentum of the unit. Like a fly wheel effect. Constant torque should be about 10 pounds inside the rotating housing. 30 pound pull force solenoid, with a 20 pound return spring and a one inch air gap between magnets on the rotor and housing producing 3.5 pounds of torque. If the air gap was closer I would need a much stronger pull force on the solenoid. The solenoid takes 192 watts of power to produce the pull force of 30 pounds to overcome magnetic forces in the housing. magnets are N42 neodymium. To overcome forces a pulsed system could take the place of the permanent magnets on the rotor. But I'm trying to not use any electric inside the housing. To control field weakening to get more speed pulsed electric would have to be incorporated into the system also a return spring would not be need. It would still use far less power to produce the same amount of horse power than a normal electric motor. I call this motor the Watson Magnet Motor or WMM for short. This motor will produce a constant push and pull force with little or no cogging.
