April 07, 2017. In Mxus we have tested a standard 198 mm stator OD (51 slots-46 magnets) with 3 turns of windings instead of the previous 4 turns by which this motor's structure has achieved 651.6 rpm unloaded as already written with good curves and 48 V. This new sample has achieved about 835...

Sorry for the mistake...dino test stops under 697 rpm as for the attached...opinions? Thanks

Thanks for the answers Spinningmagnets. Today in Mxus we have tested a standard 198 mm stator OD with 3 turns of windings instead of the previous 4 turns with motor has achieved about 650 rpm as already written. This new sample has achieved about 800 rpm but dino-test give no data below 600 rpm...

Dear Teslanv. The simulator seems an appreciable work and I think it is been designed by considering the opposite forces to the bicycle's advancement in flat: inertia, rolling resistance, air drag resistance, plus the inclined force's component for climbing. I like this simulator but I would...

Thanks for the reply. Question is which can be the achievable max speed with described Mxus configuration 46x30 mm magnets,51 windings, steel jacket, 0.5 mm lamination. This is a new project and we need of about 800 rpm. Is it possible with this standard configuration or it must be changed...

Dear Member. I have several questions regarding this motor's sizing that corresponds to PMBLDC Direct Drive chinese production by Mxus, QS motor and Others. As you know the range of power is 350-5000W but the Pedelec's regulation imposes to limit battery voltage up to 48 VDC. 1. one of the...

Thanks Rix for the answer. I have forgotten to specify that battery pack has 48V DC because EN 15194 imposes this maximum value for Pedelec. I know that usually this motor's configuration has a standard speed between 350-400 rpm but we are interested to achieve the highest speed. From what I...

We will are prototyping motor like you nedd. Can I know tire's diameter and required speed? Regards

Dear all. I'm a mechanical engineer so please excuse my ignoranza in electrical and electronic fields. I see here you are very competent in PMBLDC motor with which my start up www.minimalpowertrain.com is developping several project. We have choosen this power unit configuration that corresponds...
