Motor mount offset angle 1.25mm

Fine Adjustment of Anglewinder Geometry with the 1.25 mm Offset Motor Mount from Avant Slot

In the preparation of a 1/32 scale competition slot car, the details of geometry make the difference between a drivetrain that operates smoothly and one that generates unnecessary mechanical losses. The 1.25 mm offset motor mount from Avant Slot (ref. AV20575e) is the component that allows lateral displacement of the motor position in an anglewinder configuration, achieving optimal alignment between pinion and crown gear.

Function and Performance

The concept of offset in an anglewinder motor mount refers to the lateral displacement of the motor shaft relative to the central position of the chassis. With 1.25 mm of offset, this mount allows:

• Correction of the alignment between pinion and crown gear when the standard mounting does not provide the correct engagement.
• Reduction of friction in the transmission by achieving cleaner contact between the teeth of the pinion and the crown gear.
• Adaptation of different pinion/crown gear combinations within the anglewinder configuration without modifying the chassis.
• Fine-tuning of the mechanical setup of the car without the need to intervene in structural elements.

In anglewinder motorization, the motor is positioned at an angle relative to the rear axle, which requires precise management of distances and alignments for the transmission to operate efficiently. The use of mounts with different offset values is a common practice among the most demanding tuners.

Compatibility and Installation

This mount is designed for anglewinder setups in 1/32 scale, within the Avant Slot spare parts ecosystem. For optimal results, it is advisable to verify the combination of pinion and crown gear used, as well as the receiving chassis, before confirming the necessary offset value. Avant Slot offers different offset values in its range of mounts, so it is advisable to compare options if exploring the ideal configuration for a specific setup.

Installation and Preparation

• Check the play between pinion and crown gear with the current mount before deciding on the necessary offset.
• During installation, ensure that the motor is securely fixed to the mount to avoid vibrations.
• Check the visual and tactile alignment of the engagement once installed, turning the rear axle by hand before connecting the car to the track.
• An engagement that is too tight generates friction; one with too much play causes noise and premature wear.

Common Mistakes

• Assuming that the same offset value works for any pinion/crown gear combination: each combination may require a different adjustment.
• Installing the mount without checking the perpendicularity of the motor relative to the rear axle.
• Forgetting to review the engagement after changing the crown gear or pinion, even if the mount is the same.

Frequently Asked Questions

What does the 1.25 mm offset value in this mount actually mean?

It indicates that the motor shaft is displaced 1.25 mm from the central reference position of the standard mount. This displacement allows for adjustment of the distance between pinion and crown gear to achieve the correct engagement according to the combination of parts used.

What scale is this mount designed for?

It is designed for 1/32 scale setups, which is the standard competition scale in clubs and one of the most widespread in the slot hobby.

Is it compatible with any anglewinder motor?

The mount is developed within the Avant Slot system. To confirm compatibility with a specific motor, it is advisable to consult the brand's spare parts catalogue or contact us before installation.

How do I know if I need a 1.25 mm offset or a different value?

It depends on the combination of pinion and crown gear you use and the current position of the motor in the chassis. The most practical way is to measure the engagement play with the current mount and compare it with the desired result. If the engagement is too tight or has too much play, changing the offset value is the cleanest solution.

Can I use this mount in an inline or sidewinder configuration?

No. This mount is specifically designed for anglewinder configurations, where the motor is mounted at an angle relative to the rear axle. It is not applicable to inline (longitudinal motor) or sidewinder (transversal motor) setups.

The Avant Slot AV20575e anglewinder motor mount with 1.25 mm offset is a precision replacement part for 1/32 scale slot car builds. Designed to fine-tune the alignment between pinion and crown gear in anglewinder setups, it helps reduce mechanical friction and improve transmission efficiency. An essential tuning component for competitive slot car racers looking to optimize their drivetrain geometry.
