Question #: 13859

Question: what causes one of my x-axis motors to overheat.

Current Solution

What can cause a stepper motor to overheat can be related to a few things. First, it good to know that stepper motors will normally be hot to the touch and you should not worry about this. There is a ton of current running through the coils of a stepper motor, and current will cause heat to build up.

Energy comes in many basic forms: movement, heat and light. Stepper motors don't produce light, so we can rule that out, so you have movement and heat. When the stepper motor is not moving, the current is still trying to make sure the stepper motor is holding its position and since movement is not a factor here, heat will build up.

If the heat worries you, you can keep the cnc machine moving, or turned off. There will still be heat when moving, but not all of the current is being used as heat. You can also consider lowering the allowable current draw using the stepper motor driver's dip switches.

  • WHAT CAUSES THE SKY TO BE BLUE?

    Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.

  • WHAT CAUSES RINGING IN YOUR EAR AND HOW CAN YOU STOP IT?

    Tinnitus . Learn to love it. No really you should see a doctor. Make sure. White noise will help you sleep when it gets loud.

    Additional Information:
    I learned, too late, that if a sudden loud event causes tinnitus, see an audiologist IMMEDIATELY. They can do something about it if addressed within a day or so.

    Wear hearing protection...always. Loud noises trigger my tinnitus, and headphones and ear plugs (when out & about or at the movies, subway, etc) help tremendously. Mine are rated 33dB.

  • MY MOTORS GET REALLY HOT TO THE TOUCH.

    If your motors are hot to the touch, this is normal. Current is being drawn by the motor coils as the motor moves and as the motor stays at a position. If the motor is not using the current in the coils to move (holding it's position), the energy will be translated as heat (rather than motion, sound or light). Even while moving, some of the energy will be lost as heat. Remember that energy cannot be created nor destroyed.

  • DON'T WANT TO USE MY OWN MOTORS FOR THE REDLEAF CNC COMPUTER SYSTEM.

    That shouldn't be a problem. I will need the current rating for the motors. We can subtract the price of the motors. and you can add you own. If you want us to solder the cable to the round connectors and them motor, you would need to send the motors to us.

    Let me know and I can send a paypal invoice for the redLeaf without motors.

  • I HAVE ONE OF YOUR SMALLER STEPPER MOTORS RUNNING MY X AXIS BRIDGE CRANE AND IF IT IS MOVED TO FAST THE MOTOR SOUNDS LIKE SKIPPING STEPS WILL 651OZ REQUIRE A DIFFERENT POWER SUPPLY CONTROLER?

    Yes, the 651 oz/in motor requires a driver that is compatible to the motors (the motor will draw 6 amps max and the driver paired with this motor will be able to allow for a 6 amp draw). I would also recommend a 36 volt power supply for better high velocity performance.
