Reedy Sonic SP5 25.5 A-Spec Competition Stock Motor
Reedy has introduced its all-new Sonic SP5 25.5 A-Spec stock motors with minor changes to the stator improving torque for racers who utilise 25.5 motors in competition. The incredible performance of the SP5 starts at the heart of the motor, the stator. Designed in-house, the stator’s profile is intended to achieve maximum torque and power output without sacrificing RPM. High-quality copper magnet wire, sized to the maximum that the rules allow and wound with care to keep resistance near the legal minimum, is treated with heat transfer epoxy to dissipate heat and reduce internal temperatures resulting in less fade over the course of the race. An oversized collector ring not only dissipates heat, but in conjunction with thick solder tabs, reduces resistance and power loss. The balanced rotor features a high-strength magnet that takes full advantage of dimensional rules to produce fade-free power with maximum effectiveness. The rotor is supported by precision stainless steel ball bearings to accommodate high RPM loads with exceptional efficiency and reliability. Like all Reedy Sonic motors, a high-quality sensor board rounds out the motor’s interior. Externally, the SP5 utilizes a lightweight two-piece CNC machined aluminium housing with an aluminium endcap and timing adjustability to accommodate fine-tuning for specific applications.
