Causes of Bad Brushes in Golf Cart Motor
The following are the causes of bad brushes in golf cart motor:
- Overheating: The brushes warp or deform when the motor gets too hot, causing poor performance.
- Voltage Irregularities: Voltage fluctuations create inconsistent contact with the commutator and cause the brushes to wear unevenly.
- Wear and Tear: The brushes in a motor will naturally wear down from use after a while, making them less effective at conducting electricity.
- Contamination: The brushes become dirty or contaminated with dust, dirt, or debris, which will cause interference with contact with the motor’s commutator.
- Improper Maintenance: Lack of regular maintenance on a golf cart motor, like cleaning or lubricating the brushes, can cause the brush to fail.
- Mechanical Damage: Any physical damage to the brushes or the motor can cause problems.
Why Do Golf Cart Motor Brushes Wear out Fast?
Higher operating speeds, increased loads, higher temperatures, higher voltages, poor maintenance, and dirt are reasons why golf cart motor brushes wear out fast.
Motor brushes are made of carbon or graphite material, are relatively soft, and can wear out over time due to the friction and heat generated during normal motor operation.
