Scaleauto SC-18 Slim Can Motor - 25000 RPM (Shaft 1.5mm)

The Slim Can SC-18 Motor: High Performance in a Compact Format for Slot

When space within the chassis is the main constraint, the SC-18 from Scaleauto responds with a Slim Can design intended to perform where other motors do not fit. With 25,000 rpm at 12V and a torque of 82 gr*cm, it offers a well-calibrated balance between top speed and corner exit response, without compromising reliability during long training or competition sessions.

Main Features

• Type: Slim Can (narrow can).
• Speed: 25,000 RPM at 12V.
• Torque: 82 gr*cm.
• Current Draw: 0.14 A.
• Dimensions: 26.9 × 15.5 × 12 mm.
• Axle: 1.5 mm diameter.
• Endbell: Sealed (Sealed Endbell).

Behaviour and Performance

The SC-18 stands out for its very smooth and progressive operation. The 25,000 rpm at 12V translates into a notable top speed, but it is the torque of 82 gr*cm that provides the immediate acceleration highly valued on technical circuits with many curves. Its low current draw of 0.14 A also makes it a prudent choice for those using mid-range power supplies, as it does not overload the circuit or generate excessive heat during prolonged sessions.

The dimensions of 26.9 × 15.5 × 12 mm allow it to be integrated into low-profile bodies without compromising the centre of gravity, resulting in greater stability through corners. The sealed endbell adds mechanical protection against dust and circuit particles, extending the motor's lifespan and reducing the need for maintenance between races.

Recommended Applications

The SC-18 is aimed at slot car chassis in scales 1/32 and 1/24 that use specific cradles for Slim type motors. Its 1.5 mm axle is compatible with standard pinions for narrow motors, making integration into common setups straightforward and without additional modifications.

It is a balanced option for both speed tracks and slot rally layouts with many chicanes, thanks to the combination of good acceleration and controlled top speed. Preparers looking for a reliable, homologable replacement motor with consistent performance will find the SC-18 a solid reference within the Scaleauto catalogue.

Usage Recommendations

• Ensure that your chassis cradle accommodates Slim Can type motors before assembly.
• Check the compatibility of the pinion with the 1.5 mm axle to avoid play or excessive tightening.
• Although the sealed endbell reduces maintenance, it is advisable to periodically check the braids to ensure optimal contact with the collector.
• For more aggressive performance, pair it with tyres of appropriate hardness for the track type and a gear ratio suited to the circuit length.

Frequently Asked Questions

Is the SC-18 compatible with any Slim Can chassis on the market?

The SC-18 follows the standard dimensions of Slim Can motors (26.9 × 15.5 × 12 mm), so it is compatible with most cradles designed for this format in scales 1/32 and 1/24. However, we recommend confirming the cradle measurements of your chassis before assembly.

What pinion do I need for the 1.5 mm axle?

You need pinions with a central hole of 1.5 mm, which is the usual standard for narrow motors in slot. Scaleauto and other brands in the sector offer compatible pinions in different modules.

Is the SC-18 designed for competition or recreational use?

Its balance between torque, speed, and consumption makes it suitable for both environments. In club competition, it is very competitive in Slim Can categories; in recreational use, its smooth operation and reliability are its main advantages.

Does it require a break-in period before being used in a race?

Like any brushed motor, the SC-18 slightly improves its performance after a gentle break-in at low voltage (around 6-8V for a few minutes). It is not strictly mandatory, but it is advisable to settle the collector and the braids.

Does the sealed endbell prevent cleaning or replacing the braids?

The sealed endbell offers greater mechanical protection, but in motors of this type, access to the braids may be limited. Consult the specific instructions from Scaleauto or contact your trusted store if you need to perform deep maintenance.

What is the difference between the SC-18 and other Slim Can motors from Scaleauto?

Scaleauto has several Slim Can motors with different torque and rpm curves. The SC-18 is positioned in a middle ground: sufficient speed for fast tracks and ample torque for technical circuits, making it especially versatile compared to other references more oriented towards pure speed or maximum torque.

The Scaleauto SC-18 Slim Can motor delivers 25,000 rpm at 12V with a torque of 82 gr*cm, making it a top-tier replacement motor for 1/32 and 1/24 slot car chassis requiring narrow Slim Can units. With a 1.5mm axle diameter and sealed endbell, it offers outstanding reliability and smooth performance for both club racing and recreational use. A precise, efficient and durable choice for slot car enthusiasts seeking consistent lap times and easy integration into standard Slim Can motor pods.
