Hello to all forum members.
Many thanks for sharing the information about the SMG180/120.
This is my first post, so I'll briefly introduce myself. I'm in the middle of a low-budget motorbike project. For a few reasons, the ideal drive for my project is an axial flux motor such as (virtual only) D144/576 from Ashwoods.
The Phi271, Yasa P400, Evo AF125/130 are beyond my price range and need a little more than my modest 290V/250A/6.3KWh, so I abandoned the axial flux motor search and came across two smallest SMG on the market from Bosch 180/120 and 138/80 (both most probably designed by EM Motive)
SMG180/120 is quite cheap (~ 拢 2,500-3,000 brand new for PSA hybrid cars) and readily available, it's small, 29-32Kg, 35-90KW, 160-200Nm, 250-400V (depending on OEM application), 12,800 rpm and water cooled ...
Honestly, it is difficult for me to find something technically better in the budget I founded. Maybe with a small exception of the Dynax 500e from Compact Dynamics.
Please share your information if you have anything else about the SMG180, specially if someone managed to run it on an equally low-cost inverter such as EPF2.3 or INVCON2.3. 馃榾
Thanks

That's small for an EV motor, but still seems large for a bike. Wouldn't the SMG 138/80, running at high voltage, be a better fit for a bike? I haven't seen any good specs for it, other than the Bosch chart of motor applications in hybids and BEVs.

Hi Brian,
As you said 180/120 is not the smallest for the eBike, especially with the battery it needs. Of course, the SMG138/80 is much smaller (11 Kg) and will fit without any problems even into the smaller frame than my Suzuki SV650, and the battery will last much longer. But these 200Nm won't let me sleep. I'll be sick if I don't try. 馃お
