ROAR ANNOUNCEMENTS
2/15/08 - Brushless Motor Announcment
ROAR has recently approved the initial set of rules for Stock and Super Stock Brushless motors designated as 17.5 and 13.5 turns respectively. The products are currently under inspection at the ROAR designated motor laboratory, and a problem has been verified during the first few inspections that has forced ROAR to revisit the induction requirements for both of these motors.
The inductance requirements were developed using measurements from one manufacturer and targeted by the other manufacturers during the design and prototyping process of their products. It came to light early in the final drafting of the rules that there might be incorrect values for the related induction measurements. This has now been verified in the current approval process. The original plan was to inspect motors from several manufacturers to identify the mean and the range value for the 17.5 and 13.5 motors, and then address the rules for those motors in the rulebook. The mean value for each motor has now been determined and ROAR is now waiting for the other manufacturers motors to arrive for inspection to determine the final range of these values.
This situation makes it impossible to establish a final approval for the manufacturer that has just now completed the approval process, and it appears that the next manufacturer will not have delivered his motors in time to inspect before the deadline to participate in the upcoming nationals for carpet onroad and carpet oval. ROAR intends to address this situation in the following manner.
The first manufacturer has passed all tests and inspections for both 13.5T and 17.5T brushless motors, less the inductance measurements. This manufacturer will receive a �Conditional� approval of his products for purpose of eligibility for the upcoming racing events. The �Conditional� approval will be effective immediately and last till May 31, 2008. It is anticipated additional manufacturers products will have been inspected by May 31,2008, and the range of the values will then be established. The rules will be changed at that time and the �Conditional� approval will be made a full approval.
All other manufacturers products for these motor classes will follow the same inspection and test procedures, and granted the same �Conditional� approval to their products provided they have been submitted and inspected prior to May 31, 2008.
The rules covering the required wind inductance for these two motor classes will be revised to reflect the new inductance value and range when sufficient data has been collected to make those rule changes. This could be before May 31, 2008, but no later. All motors received from new manufacturers after the rules have been officially changed will be subject to those new values and range, and will be inspected as such. There will be no �Conditional� approvals awarded after these rules have been changed reflecting the new values and range.
The purpose for this plan is to give the drivers an opportunity to acquire these products from a reliable manufacturer with the confidence that these products will be eligible for the upcoming ROAR events in both the short and long term. It also allows ROAR to publish the name of the manufacturers that are supplying legitimate products even though ROAR is a technically prevented from awarding a full approval of those products. Please continue to monitor the ROAR website announcements and approved motor listing for brushless motors to find the latest information regarding the approval of these products in the future.
The brushless motors now with �Conditional� approval for ROAR events are:
