The Sloting Plus Speed 5 Motor: Contained Power and Balanced Rotor for Long Can

Within the range of Sloting Plus motors, the Speed 5 (reference SP090005) occupies a clear position: it offers a speed of 21000 RPM at 12V with a torque of 300 g.cm, all in a long can motor designed to be reliably mounted in medium-high level 1/32 setups. The balanced rotor is the detail that best defines its philosophy: less vibration at high speed means more consistency in response and less wear on the entire drivetrain.

Main Features

• RPM: 21000 at 12V
• Torque: 300 g.cm at 12V
• Weight: 32 g
• Format: closed can, long can
• Magnetic Field: approx. 3-4 UMS (scale 0-20)
• Balanced rotor to minimize vibrations at high revolutions

Behaviour and Performance

The magnetic field situated in the 3-4 UMS range makes it a motor with very contained electromagnetic braking. This translates into a freer and more linear response when releasing the trigger, which demands greater precision from the driver but rewards with better lap times on technical circuits when the driver is tuned in. It is not a motor intended for beginners, but for those who already know their car and seek an upgrade in performance.

The 300 g.cm of torque ensures a strong corner exit without spiking consumption, and the 21000 RPM allows for competitive top speeds on medium-length tracks. The weight of 32 g is perfectly reasonable for a long can motor, without excessively penalizing the mass distribution of the chassis.

Recommended Applications

As a long can motor, its natural mounting is in 1/32 cars that accept this format, both in inline configuration and in other positions depending on the chassis. It is particularly suitable for:

• Club setups aimed at free or semi-free motor categories.
• Chassis that require a motor with notable torque without resorting to aggressive magnetic fields.
• Drivers who prefer a motor with good progression and clean response over strong braking motors.

Usage Recommendations

As with any high RPM motor, a progressive run-in is advisable before demanding maximum performance. Ensure that the pinion is well aligned with the crown gear and that the braids make clean contact with the collector from the outset. A careful assembly from the beginning extends the motor's lifespan and keeps its performance stable for longer.

Given its reduced magnetic field, combine it with a guide and braids in good condition: any loss of contact will be more noticeable than in motors with greater electromagnetic braking.

Frequently Asked Questions

What is the difference between the Speed 5 and other motors in the Sloting Plus range?

The Speed 5 is distinguished by its balance between torque (300 g.cm) and speed (21000 RPM) at 12V, with a very low magnetic field (3-4 UMS). Other motors in the range may have higher or lower torque, different RPM, or different magnetic fields depending on the application for which they are designed.

Is it suitable for club racing?

Yes, as long as the category regulations allow its use. Its low magnetic field and performance make it interesting in semi-free or free motor categories where progressive response is valued over electromagnetic braking.

Why is the balanced rotor important?

At high speeds, an unbalanced rotor generates vibrations that are transmitted to the chassis, affecting the guide's contact with the rail and accelerating the wear of bearings and pinion. The balancing of the Speed 5 rotor reduces this effect, improving the car's stability and the motor's durability.

What does a magnetic field of 3-4 UMS imply in practice?

The UMS scale measures the electromagnetic braking force of the motor. A value of 3-4 out of 20 indicates very gentle braking: the car hardly slows down when releasing the throttle, which requires greater anticipation in braking but allows for smoother and faster driving on circuits that the driver knows well.

What type of chassis is this motor compatible with?

As a long can motor, it is compatible with 1/32 chassis that accept this format. Always check your chassis specifications before mounting to confirm dimensional compatibility.

Does it require a run-in period?

Yes. A progressive run-in with low voltages is recommended before operating at full power. This seats the brushes of the collector, improves internal contact, and stabilizes the motor's performance from the start.

The Sloting Plus Speed 5 motor (SP090005) is a long-can 1/32 slot car motor delivering 21000 RPM and 300 g.cm torque at 12V, featuring a balanced rotor for reduced vibration at high speeds. With an ultra-low magnetic braking field of approximately 3-4 UMS, it suits competitive club racing setups where linear throttle response and consistent performance are priorities. Weighing just 32 g, it integrates cleanly into long-can compatible chassis without compromising weight distribution.
