Some info on bmc motors, some will already be aware of this info.
Brief rundown: original motor from china factory ( apparantly design development involved ezee company), ezee not so long ago starts getting the motors made from different factory in china ( not bmc but were originally getting from bmc china).
Bmc china motor being sold a few places for a while ( including superkids website........what the??), is sold as a 350watt motor but is actually a 250watt rated motor but 350watt sticks as its rated power. Ananda brand controller is supplied with motor to run on 36v, motor is wound for 36v use.
Teamhybrid call the motor "puma' motor, quite a few problems are identified ( eg keyway needed on axle to stabilise sideways movement), bmc rectifies the problems with input from TH ( and others). Bmc china makes higher power version by changing windings and propose its a 500watt continuous rated motor ( not verified if it is or not). Freewheel mechinism originally designed for 250watt continuous motor, a number of 500watt motors with freewheel mechanism are produced, later bmc china make 500watt version without freewheel mechanism for fear of freewheel failure ( power over its rated specs).
Various controllers used on 350watt ( i.e. 250watt version) at 36volts no problem, at 48v problem identified that higher switching speed controllers needed ( long process and problem identified by "fetch"), various controllers found to be modifiable to run bmc over 48v ( by changing 'crystal', some new controllers are found with higher switching speed chips (infineon, modified v2 & others not posted). Bmc china begin designing 1kw version from scratch to have components rated for higher power use ( including freewheel) release date unknown.
Bmc India plant starts producing 250watt version from some technology transfer from chinese plant. This thread appears anouncing new bmc motor ( i.e. 250watt version from Indian plant being supplied to usa ).
So my view would be there is probably going to be a very similar process happens to the indian made bmc motor that the chinese bmc motor went through ( from what I can gather there is very little communication between china/india plants),
other questions would be are the components in the indian made motors going to be as good as quality as in the chinese made ones.. eg nylon gears in chinese motor sourced in japan. Other issues such as metal used to make side plates quite important ( the threads for gears and disc are inserts), the ring gear quality etc etc. I think these are all unknowns on the indian made motor at present.
