SLOT INDUSTRY MOTOR 17,800 rpm.

The RevoSlot RS-055 Slot Industry motor is the brand's offering for those who prioritise control and progressiveness over top speed.

Designed within RevoSlot's 1/32 spare parts range, this long-can motor combines moderate RPM figures with a generous magnetic field, achieving a balance that is particularly appreciated on technical circuits and in categories where drivability makes a difference.

Main features

• Nominal speed: 17,800 rpm at 12V
• Consumption: 0.12 Amp at 12V
• Magnetic field: 7.5 on the UMS scale
• Format: long can
• Mounting position: Inline or Anglewinder

The low consumption of 0.12 Amp not only favours the electrical efficiency of the assembly but also contributes to a smoother trigger response, resulting in less oversteer on corner exits and greater ease of driving for both novice and experienced drivers.

Behaviour and performance

With 17,800 rpm, the RS-055 does not compete in top speed with high-end motors, but that is not its objective. Its linear and progressive power delivery makes it a reliable tool for tuning the chassis without constantly battling with the car. In the hands of a driver who maintains the racing line, lap times can match or exceed those of more aggressive setups.

The magnetic field of 7.5 UMS provides a clearly perceptible loading effect on the track: braking is more secure, cornering becomes more consistent, and the overall feeling of grip is very natural. It is not an exaggerated field that masks mistakes, but just enough to provide confidence without sacrificing feedback to the driver.

Recommended applications

Its mounting versatility —both in Inline and Anglewinder positions— significantly expands the range of compatible chassis within the 1/32 catalogue. It is particularly interesting for:

• Club categories that limit maximum RPM or value technical driving.
• Circuits with many slow corners and twisty sections where torque matters more than top speed.
• Drivers who are taking their first steps in car preparation and want a predictable motor.
• Slot rally configurations where stability and smooth delivery are key.

Usage recommendations

To get the most out of the RS-055, it is advisable to adjust the gear ratio (pinion/crown gear) according to the circuit. As it is a motor with moderate RPM, a longer gearing can help better exploit its torque on fast sections, while a shorter gearing is beneficial on very slow circuits.

Always check the correct alignment of the motor in the motor holder before tightening it definitively, especially in Anglewinder setups, where a slight misalignment can cause vibration and premature wear of the transmission. The braid should be in good condition and make clean contact to keep actual consumption stable.

Frequently asked questions

Is the RS-055 compatible with chassis from other brands or only with those from RevoSlot?

The long-can format is standard in the 1/32 slot world, so it fits most motor holders designed for this type of casing. However, it is always advisable to verify the dimensions of your specific chassis before installation.

What is the difference between mounting it in Inline and Anglewinder positions?

In the Inline position, the motor is aligned with the rear axle (perpendicular to it), which lowers the car's centre of gravity. In the Anglewinder position, the motor is placed at an angle to the axle, allowing for different weight distributions depending on the chassis. Both are possible with this motor thanks to its long-can design.

At what voltage should I use the RS-055?

The indicated specifications —17,800 rpm and 0.12 Amp— correspond to operation at 12V, which is the most common voltage in club tracks and home setups with regulated power supplies.

Is the 7.5 UMS magnetic field high for competition categories?

It depends on the regulations of each category. The value of 7.5 on the UMS scale is considered a medium-high magnetic field, providing good grip without reaching the levels of motors that are more glued to the track. Always check your category's regulations before homologating it.

Does it need a break-in period before using it at full performance?

Like any brushed motor, a gentle initial break-in —at reduced voltage and in both directions for a few minutes— helps to settle the internal contacts and prolong its lifespan. It is not mandatory, but it is advisable.

The RevoSlot RS-055 Slot Industry motor delivers 17,800 rpm at 12V with a 7.5 UMS magnetic field, making it a reliable choice for 1/32 slot car racing. Its long-can design allows both inline and anglewinder configurations, offering smooth power delivery and consistent grip on technical layouts. A great option for club racing categories that value drivability and progressive throttle response over raw top speed.
