Reedy Sonic 540-SP5 Spec Motors
Reedy has released its all-new Sonic SP5 stock motor range. Featuring an all-new and unique design, the performance of the SP5 starts with 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. A 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 utilises a lightweight two-piece CNC machined aluminium housing with an aluminium endcap and timing adjustability to accommodate fine-tuning for specific applications.
