Shengyi Hub Motors - Nomenclature

[Jodel]

Folks, out of interest does anyone know how Shengyi label their hub-motors?

I have the DWG22C motor and would like to ‘decipher’ the information printed on the motor casing. In the attached image (from the Woosh site) my guess at the data would be:


SY – Manufacturer – Shengyi
22 – Maximum amps
48 – 48 Volts
700C – Motor rpm wound for this wheel rim size
The next lot I couldn’t really guess.
250W – rated continuous power.

What does the panel think?

SY22 is the hub model DGW22 nothing to do with current.
The next assumptions are likely correct that the hub is wound for 48v for a 700c rim.

The rest may be related to factory or customer serial no (in this case Woosh ).
