MINI MAGNETIC MOTOR GAUGE

Discover the real power of your motor before hitting the track with the Mini Magnetic Gauge CDC-MMM001 from CDC Slot

In the preparation of a competitive slot car, there are variables that cannot be left to chance. The magnetic downforce generated by the motor is one of them: it determines how much grip the car has during direction changes and can make the difference between complying with your club's UMS technical regulations or being out of the race before it even starts. The CDC-MMM001 provides you with that information directly, reliably, and in a matter of seconds.

Main features

• Precision of 0.01 grams: digital display that offers very fine readings, sufficient to detect differences between motors of the same reference.
• Dual measurement mode: allows you to measure the motor individually or directly installed in the chassis, thus obtaining the actual traction it exerts on the track.
• Multipurpose lid: the lid of the gauge can be used as an auxiliary plate to weigh small parts or motors, turning the CDC-MMM001 into a 2-in-1 tool.
• Ultracompact design: its mini format makes it easy to transport in any tool kit, without taking up unnecessary space on the workbench or in the club bag.

Recommended applications

The CDC-MMM001 is particularly useful in three specific situations:

1. Pre-competition verification: check that the magnetic attraction of your motor complies with the limit set by the technical regulations before passing UMS verification. No surprises at the control table.
2. Motor selection and comparison: when you have several motors available, you can measure each one and choose the one that best fits the characteristics of the circuit or the regulations of the category you are racing in.
3. Wear monitoring: a motor that has run for many hours may lose magnetic strength. Periodic measurement helps you detect that loss before it affects track performance.

Behaviour and performance

The key to this gauge lies in its duality of use. Measuring the motor outside the chassis gives you a baseline reference, but the most valuable reading is the one you obtain with the motor mounted: at that moment you are measuring the effective attraction on the track, which can vary depending on the chassis, the motor position, and the distance to the rail. That real reading is what matters in a serious technical verification.

With a resolution of 0.01 grams, the CDC-MMM001 allows for fine adjustments that other less precise gauges simply cannot offer. For competitors working with tight margins, that tenth of a gram can be decisive.

Ideal for…

• Slot racers competing in championships with technical verification of magnetic force.
• Team preparers and mechanics who need to homologate motors before each race.
• Discerning hobbyists who want to know the exact behaviour of each motor in their collection.
• Clubs and organisers looking for a portable and reliable tool for the verification table.

Frequently asked questions

What units of measurement does the CDC-MMM001 use?

The device provides readings in grams with a resolution of 0.01 grams, allowing for very precise comparisons between different motors.

Can I measure the motor mounted in the chassis without disassembling it?

Yes. One of the advantages of the CDC-MMM001 is precisely that: it allows you to measure the magnetic attraction with the motor already installed in the car, obtaining the real downforce data generated on the track.

Is it suitable for any type of slot motor?

The gauge is compatible with slot motors in general, regardless of their configuration (inline, sidewinder, or anglewinder). What matters is the magnetic attraction of the assembly, not the motor's arrangement.

Can the lid be used as a scale for small parts?

Yes. The lid of the gauge is designed to function as an auxiliary plate, allowing you to weigh small parts or individual motors, adding an extra function without needing another tool.

Is it useful outside of competition?

Absolutely. Although its most obvious use is pre-race technical verification, it is also very practical for comparing motors, detecting loss of magnetic strength due to wear, or simply getting to know the material you have in the workshop better.

What is the difference between measuring the motor loose and measuring it in the chassis?

Measuring the motor loose gives a baseline reference of its intrinsic magnetic strength. Measuring it in the chassis reflects the actual attraction on the track, which can vary depending on the type of chassis, mounting height, and other mechanical factors. For regulatory verifications, the relevant data is usually that of the mounted assembly.

The CDC-MMM001 mini magnetic motor gauge is an essential slot car workshop tool for competitive racers and serious hobbyists. With a precision of 0.01 grams, it accurately measures the magnetic downforce generated by slot car motors — both independently and when mounted on the chassis — making it perfect for pre-race UMS technical scrutineering, motor selection, and performance tuning. Compact and portable, it fits easily in any tool kit and doubles as a small parts scale thanks to its multifunctional lid. A must-have addition to any slot car preparation bench.
