Force Analysisof Heavy Duty Transmission Drum As one of the main components of the belt conveyor, the design of the transmission roller often uses the empirical formula method, and adopts a higher safety factor to ensure the reliability of the roller. The disadvantage of this method is that the roller structure is too large, the …
I have been working on Simplorer-Maxwell Co-simulation recently. There is so little information on this topic that I can only summarize some experience on my own. I am going to share it with you to prevent you from being stuck with similar problems in the future. 1. About the setting of external inductance and resistance …
1. Overview For motor engineers, motor design often involves the interaction between the control system and the motor itself. In previous versions, this had to be done in Simplorer software, which not only increased corporate costs, but also required engineers to master the use of Simplorer software, as well as the simulation settings and simulation …
Simulink and COMSOL Co-Simulation Demand background Matlab/Simulink is used for control system simulation, and COMSOL is used for model finite element simulation. If the finite element model is part of the control system, the two need to be combined to achieve collaborative simulation of Simulink and COMSOL. Before COMSOL 3.5 (including the previous FEMLAB), a …
Flat wire motors, also known as flat motors, are a special motor design that works similarly to traditional round wire motors, but differs in winding structure and heat dissipation performance.The working principle is based on the interaction of magnetic fields to generate torque. When current passes through the coils of a flat wire motor, a …
This solution uses hydraulic method to perform mechanical weak magnetic field adjustment, and its mechanical principle is similar to the CVVT valve adjustment technology of mechanical engines. CVVT technology uses hydraulic transmission to adjust the engine intake volume according to the engine speed and then adjust the engine’s working efficiency. The magnetic solution uses hydraulic …

The software can be used to design any multi-phase single-layer or double-layer windings. It supports both concentrated windings and distributed windings. It can analyze winding arrangement, MMF waveform, star diagram, winding coefficients, etc., and can generate reports. Winding Design Software SWAT-EM. The screenshot is attached below:
Demagnetization simulation method of IPM permanent magnet synchronous motor in ANSYS Maxwell R18.1 This case is about the demagnetization of the rotor magnets caused by excessive current. It is necessary to demonstrate the comparison of each opposite electromotive force of no-load operation analysis before increasing the current, and the comparison of each opposite electromotive force …

ANSOFT Modeling 1. Establish the motor model in ANSOFT software Step 1: Draw the motor model in ANSOFT Step 2: Select the “Export” item under the “Modeler” menu and the following window will appear. Select to save as a “step” format file. You can now exit the ANSOFT …
I did a Maxwell-simpler cosimulation of PMDC . It feels much more complicated than AC induction motor, mainly because neither MAXWELL nor SIMPLORER has a commutator module for PMDC, and all must be controlled by switches. For simplicity, the motor model uses the simplest three-slot motor, and the mesh is fully automatic.Finite element model and …
