MAIN REASONS WHY FORKLIFT MOTORS BURN OUT
Th5
Forklift seat-type motors can burn out due to several main reasons:
🔥 1. Continuous Overloading
-
Cause: The forklift lifts or moves loads beyond its designed capacity for extended periods.
-
Consequence: The motor operates beyond its rated capacity, generates excessive heat, and burns the internal windings.
⚡ 2. Unstable or Incorrect Power Supply
-
Cause: Using the wrong type of battery, incorrect voltage, or an unstable electrical system.
-
Consequence: The motor runs under improper technical conditions, heats up easily, and burns out.
🧊 3. Poor or Non-Functional Cooling System (if equipped)
-
Cause: Cooling fan is broken, or ventilation slots are clogged with dust or blocked.
-
Consequence: Heat cannot dissipate → motor overheats → burns out.
🛠️ 4. Improper or Irregular Maintenance
-
Cause: Failure to check brushes, bearings, electrical contact points, or presence of oil and dust around the motor.
-
Consequence: Increased friction and heat, short circuits → motor burns out.
⚙️ 5. Technical Faults from the Controller
-
Cause: The controller supplies incorrect current to the motor (too high or unregulated).
-
Consequence: The motor is forced to operate abnormally → burns out.
🧯 6. Water or Moisture Ingress
-
Cause: Operating the forklift in wet environments or incorrect washing practices.
-
Consequence: Causes internal short circuits and burning of motor windings.
✅ Prevention Tips:
-
Avoid overloading.
-
Regularly check batteries and voltage levels.
-
Perform routine maintenance on motors and controllers.
-
Clean the cooling fan and air vents.
-
Avoid exposing forklifts to wet environments.
Do you know what type (AC/DC) or brand of motor your forklift uses? I can help with further analysis if you provide more details.
