I am proud to announce that BMI Racing has now expanded and we now have our own line of blueprinted 19 turn and stock motors. Our motors are being hand built by Joe Buttacavoli (Joe B. on rc tech). Joe has been building motors for 20 years and has built some of the most unbelievable motors I have ever run or seen. He will be able to answer, along with myself, any questions you may have regarding our motors. Now for the details on what will be done to the motors
All of the motor's bushings are honed at my shop .0005(5 tenths of a thousanth) over the shaft size and also honed on center of the magnets. This eliminates the need for breaking in the bushings or polishing. The brush hoods are meticulously alligned using satin texture face, flat front test brushes of the same brand that will be used in each specific motor. Although this is very time consuming, it is the only method that would assure dead center brush, comm contact.
The armature is shimmed using high temperature, long lasting teflon washers to be centered within the magnetic field.
The motor magnets are zapped with a Thunder R/C Magnet Zapper that generates 3 times the magnetic field required to saturate the motor magnets.
All comms are cut on a Hudy Auto Executive Comm Lathe with a diamond bit that is calibrated weekly (lathe is calibrated to assure v guides are perpendicular and parallel to the tool block and the diamond bit is inspected).
The brushes are fully seated and motor spring/brush combinations are used based on application described by the customer. The motor is then Dyno tuned and tweaked on a Competition Electronics Turbo 45 Dyno. A computer printout is supplied with each motor along with an extra set of brushes that were used in the motor when we built it.
Any BMI Racing motor will be supported with "FREE" magnet zapping for the life of the motor. If there are any questions, please feel free to ask. We are here to help. Thanks for looking
