Motor SC-12

The SC-12: the Scaleauto motor that balances rpm and torque in every corner

Scaleauto has been a reference in the slot preparation world for years, and the SC-12 Motor (reference SC-0012B) is a clear example of that philosophy: an L-can motor built to deliver predictable, controllable, and competitive performance without sacrificing reliability.

Main features

• No-load speed: 25,000 rpm
• Current draw: 0.26 A
• Torque: 360 g/cm
• Can format: L-can
• Reference: SC-0012B

Behaviour and performance

With 25,000 rpm and 360 g/cm of torque, the SC-12 sits in a performance range that is very advantageous for club racing and high-level recreational preparation. The torque generated allows for solid corner exits without the need for excessively long crowns, while the contained current draw of 0.26 A makes it compatible with standard household power supplies and reduces heating during long sessions.

The L-can format is one of the most widespread in slot car preparation benches, making it easy to install in a wide variety of chassis. Its standard size simplifies centring and adjustment without aggressive modifications to the bench.

Recommended applications

This motor fits particularly well in inline and sidewinder configurations where a block with a progressive torque curve is sought. It is a solid option for club categories with motor limitations, as well as for enthusiasts looking to take a step forward in preparing their car without entering the most extreme rpm range.

Usage recommendations

• Check the alignment of the pinion with the crown gear before the first start-up to avoid premature wear.
• Perform a progressive run-in during the first sessions to settle the braids and prolong the motor's lifespan.
• Periodically check the condition of the braids; poor contact directly translates to a loss of performance.
• Combine it with a gear ratio suitable for the circuit: technical tracks with many curves benefit from slightly longer crowns to better utilise the available torque.

Frequently asked questions

What does it mean that the motor is L-can?

L-can refers to the size and shape of the motor can. It is a very common standard format in slot preparation, compatible with most benches designed for competition motors. It facilitates installation and interchange between different blocks.

What is the difference between an inline motor and a sidewinder?

In an inline configuration, the motor is placed in line with the rear axle (longitudinal), lowering the car's centre of gravity. In a sidewinder, the motor is mounted parallel to the rear axle (transversal), allowing for greater compactness in some chassis. The SC-12 can be adapted to both configurations depending on the chassis you use.

What power supply is the SC-12 compatible with?

With a no-load current draw of 0.26 A, the SC-12 works seamlessly with standard household power supplies in the hobby. In competition, check your category's regulations to ensure the allowed voltage fits the motor's specifications.

Is it necessary to run it in before using it in competition?

Yes. Like any brushed motor, the SC-12 benefits from a progressive run-in during the first sessions. This allows the braids to settle properly on the collector and enables the motor to reach its optimal performance with less long-term wear.

What gear ratio do you recommend for this motor?

There is no universal ratio, as it depends on the circuit, the type of chassis, and the weight of the car. As a starting point, with 25,000 rpm and 360 g/cm of torque, a ratio around 3:1 – 3.5:1 usually works well on mixed tracks. Adjust according to the specific characteristics of your usual circuit.

The Scaleauto SC-12 motor (ref. SC-0012B) is a reliable L-can slot car motor delivering 25,000 rpm, 0.26 A current draw and 360 g/cm of torque. Designed for club racing and high-level recreational preparation, it offers a well-balanced power curve suitable for both inline and sidewinder configurations. A go-to choice for slot car enthusiasts looking for consistent, controllable performance on the track.
