Moreover, it is not coming with Gear set (1:3.8) and prop hub.
And, if anyone want to get it cheap, just go to Printer dispose off shop, and you can get much more, very cheap. And in Chandni Chawk of Kolkata, Brand new Rs20/- motors can give much power when the brush is reworked with brass brush plate. No winding replacement and gear change is required. And costs total comes maximum Rs.50/- if you even replace the winding too. It's 300 size motor. Thanks Title: Re: DC brushed motors Post by: jitender on March 11, 2012, 09:05:08 PM Dear KALYANPRODHAN
Can you rework the brass brush plate and do the rewinding on four identical 300 size motors for me and I will buy them for Rs 200 + shipping. Jitender |
