LowRider 13.5T 540-2 Pole Stock Racing motor

Patent Pending
ROAR Approval Pending

BRCA/EFRA Approved

We are in talks with ROAR to sort out an issue with the approval of our stock motors. We recommend tracks to use BRCA approvals as the same testing is done by BRCA and our motors are approved by BRCA

Low Rider 13.5 Turn 540-2 Pole motor:

After the success of the Low Rider modified motor, winning US and Japanese national championships, it was time for the Spec version. Offered in 21.5, 17.5 and 13.5 turn versions, the light weight and low center of gravity is carried from the modified version.

 
The heart of the Spec version is the optimized stator. After several different design approaches, we found what the unique Low Rider configuration needs for phenomenal power in the ultra competitive Spec classes. As the motor is inherently light, we could keep steel in critical areas to squeeze every ounce of power from the motor.

In the SMC tradition, motors are NOT sorted to keep the best for ourselves. Every motor is assembled, to our exact tolerances, and the “best” motors have not been cherry-picked from the lot.

Certified stators which means every motor will have a stator that is wound to a very tight tolerance of 0.50 mOhm between motors when measured from the A , B or C solder tab to the collector ring

34mm Diameter with offset mounting holes which allows the motor to be mounted 1mm lower than current motors for the lowest possible center of gravity.

50mm Length keeps the weight closer to the center of the chassis for optimal weight balance.

This motor only weighs 137 grams which makes it one of the lightest stock motor on the market and 20 grams lighter then the Monster Max.

7.2 x 12.5 sintered 42UH rotor.

Warning:  Due to the high magnetic flux inherent to the stator design, unloaded sensor deviation tests may appear to vary between bench tests. This is normal and is not a factor on a loaded motor on track.

Caution about timing: this motor has a LOT of KV. Testing has shown best results with timing approximately 8 degrees less than conventional “thin leg” Spec motors. Check your temps until you figure out timing and gearing!

Recommended Amp/Timing:  44 degrees on the Motolyser at 3.7V

We recommend you start with one teeth lower then you previous motor and adjust if need be.
