Troubleshooting Your Pneumatic Golf Cart Motor

A golf cart.

The job of a usual golf cart motor is to convert electrical energy so that your golf cart can move. Most of the time, it uses the concept of magnetism to simultaneously attract and repel the parts in order for the shafts to move. Pneumatic motors use the same concept but it uses compressed air and transforms it into energy that can power mechanical work. Pneumatic motors are not as efficient as the usual motors, which is why there are a number of problems that one can encounter with a golf cart that uses pneumatic motors. You can easily troubleshoot pneumatic motor problems.


Overheating is a common problem of any kind of motor. This is because the rotating mechanism produces heat inside the device. If the heat inside accumulates and the system is not able to dissipate the temperature properly, then it can lead to overheating. Overheating can be attributed to the parts of the motor that keeps rubbing into each other which causes the increase in heat. In order for you to solve this problem you should lubricate the motor. There are oil holes in different parts of the motor which you have to place a few drops of oil. A common symptom of an overheated motor is when you smell something burnt from the device.

Wobbly Shaft

Misaligned moving parts make the shafts of your motor wobbly. This can be easily fixed by opening your motor, inspecting the shaft and making the necessary modifications. If the shaft is misaligned, screw out the shaft and position it properly. If the shaft is wobbly because it is not secured properly into the motor, then simply screw the shaft tighter.

Motor Is Too Hot

A pneumatic motor, just like any other kind of motor, is designed so that there is proper ventilation for the heat that the device accumulates throughout its use. The most typical reason why your motor gets too hot to touch is that the heat is trapped inside the device. This should not be the case because heat has to always flow out of the vent holes. But if the holes are covered, the heat is contained within the system. To solve this problem, visually inspect the motor and see if there is any part of the cart that is blocking the vent holes and reassemble the parts so that the vent holes are left open.

Sparks in the Motor

The most dangerous kind of problem that you might encounter involves the presence of sparks inside your motor. This is often caused by rotor, stator and brushes that are damaged. To solve this problem, open your motor and inspect the rotor, stator and brushes to find out if any of them is damaged. Replace the damaged ones by following the instructions in your manual. Seeing sparks inside your motor must signal that you need to urgently pay attention to your motor. You do not want any other part of your motor to catch fire.
