These injection molded Delrin® guards for your 540 brushed or brushless motors are super slick, very durable, and thin enough to maintain clearances under the axle and between the motor and axle case. They clamp between the motor and the gear case and are indexable so you can keep the wire notch where your wire contacts are, depending on your timing.
That's right. No more hassle with removing tape from your motor (that holds your 5 hour energy bottles in place) every time you need to tear into your motor. Simply unbolt your motor from the gear case and slide off your Motor Sav'r. These guards also offer full end bell protection!
The wall thickness between the motor and gear case is 1mm and the side wall starts at 1mm and tapers to 0.75mm for the mold release. They also feature a 0.5-0.75mm gap for cooling. We have had ZERO temperature issues running these. That said, you also can easily open some vent holes with a body reamer or similar if you so desire.
Weight is 7 grams. Sold individually. Motor guard only. May require removal of motor label.
