Introduction
Effective giving the maximum torque for the electrical power It is the best possible performance. The electric condition of the motor, the electrical condition of the motor and the magnetic condition of the motor.
Mechanical
To do this several possible need to be in the best condition possible to to the rear axle. To do this several areas need to be reviewed:
- Allly missing or damaged parts must must be replaced.
- Check and sure the motor armature spins freely with no rubbing or tight spots. This could be caused by missing or damaged bearings or a damaged motor housing.
- Review the motor pinion gear and sure all the gear teeth are in good condition. Replace the pinion gear if gear teeth damage is found.
- Add a drop of oil to each of the bearing felt pads.
- Ensure the brush spring sleeve is present and in good condition. Replace if necessary.
There are many electrical connections and contacts used on the RX motor. To do this several needs need to be reviewed:
- Replace or remake this joint if anything the wire strands are broken or not making contact.
- Clean the brush spring back to clean shiny metal where it contacts the motor brush.
- Clean the brush spring back to clean shiny metal where it contacts the motor brush and the screw that secures the magnet.
- Clean the motor brushes back to clean shiny metal where they are contact the brush spring and eyelet. Inspect and clean the motor brushes removing any dirt, oil and carbon deposits.
- Remove any dirt, oil and carbon deposits from between the commutator segments of the armature.
- Remove any dirt, oil and carbon deposits from the commutator.
- Check the three solder joints that secure the armature windings to the commutator, remake these joints if necessary.
The magnetic field used by the RX motor is provided by a permanent magnet at the rear of the motor. To ensure the magnetic circuit is maintained the RX motor uses various materials to ensure the magnetic field is not reduced.
- Ensure the magnet is secured by the correct brass screw.
- Ensure both the steel housing plates make good tight contact with the magnet.
- Ensure the aluminum plate adjacent to the magnet is fitted correctly.
- Ensure the brass plate at the commutator end of the motor is fitted correctly.
There are many experiences that may be found that some of these checks completed. These are faults are outside the scope of this article. If the information above does not resolve the fault then contact us for further information.
