Shark40 motor

The Shark40: when NSR bets big on power in a compact format

The Shark40 Motor (NSR3005) is one of the standout offerings in NSR's catalogue within the short-can motor range. With 40,000 rpm and a torque of 210 g-cm at 12 V, this motor is designed for enthusiasts and competitors who need muscle without sacrificing the compactness required for a clean installation in modern chassis.

Main features

• Nominal speed: 40,000 rpm at 12 V
• Torque: 210 g-cm at 12 V
• Format: short can
• Manufacturer: NSR (reference NSR3005)

Recommended applications

As a short-can motor, the Shark40 is compatible with the most common configurations of NSR chassis in sidewinder mounting —with the motor parallel to the rear axle— and inline —with the motor perpendicular to the rear axle, in line with the car—, depending on the chassis you use. Always check compatibility with your specific chassis before installation.

Its power range places it in the high end of advanced recreational use and club racing, where the difference between motors is particularly noticeable on long straights and in the response when opening the throttle out of corners.

Behaviour and performance

The 40,000 rpm positions the Shark40 in a high-response segment. The torque of 210 g-cm ensures generous traction that translates into real acceleration and not just top speed: the car exits each corner with conviction. To harness its full potential, it is advisable to adjust the gear ratio —pinion and crown gear— according to the track, as with so much power available, the balance between top speed and acceleration makes a difference in lap times.

Usage recommendations

• Check the condition of the car's braids before installing the motor: poor electrical contact limits the actual performance of the Shark40 and can damage the motor's brushes.
• Adjust the gear ratio to the type of circuit: more development for fast tracks with long straights, more reduction for technical tracks with many curves.
• Check the alignment of the pinion with the crown gear after installation to avoid vibrations and premature wear.
• NSR offers a wide range of spare parts and consumables that allow you to keep the motor and transmission assembly in optimal condition.

Frequently asked questions

Is the Shark40 suitable for use in club championships?

It depends on your championship's regulations. With 40,000 rpm, it is in the high range; verify that your category allows motors of this type before using it in official competition.

What type of mounting can I use it for, sidewinder or inline?

Being a short-can motor, it is compatible with both configurations, sidewinder and inline, depending on the chassis. Check the NSR compatibility chart or your chassis specifications to confirm.

What pinion-crown gear ratio do you recommend for a technical track?

With such a powerful motor, on tracks with many curves, a shorter ratio (more reduction) usually works well to gain acceleration and control. The exact adjustment depends on the track and the weight of the car; test and adjust during practice sessions.

Does it need a break-in period?

Like all collector motors, the Shark40 improves its performance after a brief break-in at moderate voltage. A few minutes at low voltage before using it at full power extends its lifespan.

Is it compatible with Scalextric or Ninco tracks?

The motor itself has no relation to the track system; compatibility depends on the chassis you mount it on. What you should keep in mind is that the resulting car is compatible with the universal (Scalextric, Ninco) or sport (Scaleauto, Slot.it) track, depending on where you plan to race.
