    Gap between magnet and coils on an Axial motor

    APL, I figure it out to determine the pole arc....the pole arc is a fraction of the pole pitch. The reason for that, as you already documented on your thread is to minimize cogging torque (undesirable condition at slow speeds) as well to minimize flux leakage to nearby magnets. I read couple...

    The NEFASTUS Axial motor (Toy Version)

    Here is how the motor looks assembled The outer casing is a two part casing(not shown) that one of the halves will have a groove to put some liquid gasket. Also will have inlet and outlet ports for the coolant(ports are not shown either) Here a side cut of the motor with all the internal parts...

    Gap between magnet and coils on an Axial motor

    Folks, What you guys have to say about gap between magnets on a axial motor...same with the coils? what is the general rule of thumb? minimize the gap? keep it between a certain range?

    The NEFASTUS Axial motor (Toy Version)

    Alright!!1 her is the next update Coil design: Using the same approach as with the magnets For the man version I'm planning using powder iron cores, but for the toy version the core will be a3D printed center bar (basically air core) no coil shoes. The 3D printed core will serve as a...

    The NEFASTUS Axial motor (Toy Version)

    Thanks APL Yeah for the man version, Im planning using 10mm thick iron plates I'm playing around with FEMM changing iron back plates thickness as well with the powder iron core center bar, see how that affect the flux in the air gap. I'll share my results obtained with FEMM, see what if it make...

    The NEFASTUS Axial motor (Toy Version)

    Alright guys...here is how the rotor was constructed. I know some people will complaint about the way the rotation is transfer to the shaft via a collar with two M5 set screws, I decided to go that route because already have the bearings and shaft laying around from previous projects. The shaft...

    The NEFASTUS Axial motor (Toy Version)

    Hi Folks, I want to share the design process, material selection of an Axial motor as well as to get some advise from this community for the future version of this motor. The final (man version) version is intended to be used on a motorcycle ( A Daytona 675). The toy version however is to...

    Delta Vs Star Connection...Pros and Cons

    Folks, This maybe answered in a previous post but did I not found anything relevant when did a search, may be I didn't chose the right key words....anyways can someone want to share what are the advantages and disadvantages of delta and star Connection. Regards,

    Soft magnetic Iron cores results

    Folks, I'm being looking around ES for information regarding soft magnetic cores. There are some posts but can't find a post with actual results. Did someone out there was able to build a running motor with soft cores. Is there a video or some kind of guide on how to cast them (not the mould)...

    FEMM Simulation Help

    Fellas, Here was the problem: The magnets in the rotors were not a mirror of each other, so I have front rotor N,S,N.... then back rotor was S,N,S, so the fields were cancelling each other out, as pointed out by Peters and Major. Here is a picture with the flux no that both rotors are mirror...

    FEMM Simulation Help

    Folks, I just took a crash course video on YouTube about FEMM software to simulate an axial motor I'm working with. The flux distribution looks about right, I was expecting something like that, however the force generated is too little, around 50 N, I was expecting a lot more based on the...

    75 KW Axial Flux Motor Design Help

    Thanks for the info Openwheel, Appreciate the recommendation about making the stator lighter. I'll definitely figure out something lighter. There are some means to hold the stator to the frame, take a look at the stator segments in the picture below, M5 threaded holes that goes all the way down...
