SMC have introduced the somewhat radical Low Rider 540-size modified brushless motor. Designed to offer maximum drivability with a linear power delivery and still tons of top end, the motor also features a minimised the outer diameter, shedding the useless can and shrinking the length as much as the rules allow to. The small package drops the weight more than 17 percent from SMC’s Totemic Modified platform. And by utilising the new diameter, the mounting holes are offset to lower the motor in the motor mount. This leads to a light motor slung way down in your chassis.
As for the available power band, the bottom end is silky smooth with the stator and rotor working together to get tractable power to the ground and allowing to use more throttle with increased confidence. The mid range flows seamlessly from the bottom with no kick, a common issue in 2-pole brushless motors that tend to have hard kick in the mid range breaking traction right when you need it the most. And SMC’s stator allows the motor to rev out without feeling like it falls flat. Smooth bottom and high KVs, the result of looking at the stator from a completely different angle. The stator steel was specially selected for the power band of Mod racing, allowing very high RPM and keeping the power under control at low speeds. The rotor is tuned to the stator steel with sizing and magnet strength/heat resistance balanced for a wide range. A completely new sensor board design allows the assembly to always sit flat and square to the rotor shaft. And the end-bell and mounting cap are locked into the stator assuring bearing alignment and low vibrations.
