The incredible performance of the SP5 starts at the heart of the motor--the stator
Reedy's all-new Sonic SP5 stock motors feature an all-new and
unique design, incorporating many features that will put it at the top
of the pyramid when it comes to stock motor performance.
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.
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 utilizes a lightweight two-piece CNC machined
aluminum housing with an aluminum endcap and timing adjustability to
accommodate fine-tuning for specific applications. This lightweight
package is a welcome way to improve vehicle handling while improving
chassis tuning flexibility.
