The initial thing on this list should be the mechanical state of the motor. Mechanically, the RX motor requires being in the best state to make sure that no unnecessary energy has been lost and the motor can generate as well as transmit all the produced torque to the rear axis. For doing this, there are few areas you need to be reviewed, to find the best scalextric motor.
The first thing you should check is the parts of the motor. The missing part should be replaced. The next thing on this list is checking the spinning of the motor. If the motor spins freely, then you are ready to go or otherwise you need to check it. Check if the pinion gear works correctly. If there is some fault with it, then it should be changed and replaced with a new one. For the best performance always add a drop of oil to each and every bearing felt pad. In this way, you can keep the mechanical condition better. Miniriacing are the best brand for this although they specialise in Scalextric hire for events.
Electrical Condition of the motor
The best way to maintain the health of your motor fit is checking the electrical state of the RX motor because the electric connections help the motor to connect with the vehicle. There are a lot of electrical connections on the RX motor, for this reason, each and everyone should be checked weekly at least. You should replace any of the connection that has not been working properly. The eyelet should be inspected so that no dirt or metal oxide can accumulate there which may hamper the performance of the motor. You should remove the oil, dirt and any carbon from the commuter as well as the segments of it.
Magnetic Condition of the motor:
There is a permanent magnet in the RX motor which provides the magnetic field. The magnetic field reaches the armature and in this way the steel plates are used as the housing of the motor. For keeping the motor in good condition, you need to ensure that the magnet is secured by the proper brass screw. Next, you should confirm that the aluminium plates are working properly. If any part of the magnet seems to function wrong, that should be replaced immediately.
In this way, you can keep your RX motor in good condition.
