Reedy Sonic 540-SP5 13.5 Turn Brushless Motor

Reedy's Sonic SP5 stock motors are now offered! Including a distinct style, Reedy's Sonic SP5 integrates numerous functions that will put it at the top of the pyramid when it comes to equip motor performance.

The extraordinary performance of the SP5 begins at the heart of the motor--the stator. Designed in-house, the stator's profile is intended to attain optimum torque and power output without compromising RPM. High-quality copper magnet wire, sized to the optimum that the guidelines enable and wound with care to keep resistance near the legal minimum, is treated with heat transfer epoxy to dissipate heat and reduce internal temperatures leading to less fade throughout the race. An extra-large collector ring not just dissipates heat, however in conjunction with thick solder tabs, lowers resistance and power loss.

A well balanced rotor features a high-strength magnet that makes the most of dimensional guidelines to produce fade-free power with optimum effectiveness. The rotor is supported by precision stainless-steel ball bearings to accommodate high RPM loads with extraordinary efficiency and reliability. Like all Reedy Sonic motors, a top quality sensor board rounds out the motor's interior.

Externally, the SP5 uses a lightweight two-piece CNC machined aluminum real estate with an aluminum endcap and timing adjustability to accommodate fine-tuning for specific applications. This lightweight package is a welcome method to enhance automobile handling while improving chassis tuning flexibility.
