Does voltage matter for stepper motors?
Stepper motors are designed to work this way and it is safe to run the motors at up to 20 times the rated voltage. You will actually get better performance by running at a higher voltage than the rated voltage. Stepper motors can safely run run quite hot even when running under correct parameters.
How does voltage affect stepper motors?
Because of this vibration, the motor will also produce more audible noise. Secondly, with increased current resulting from the higher applied voltage comes an increase winding power loss. This power loss increases the temperature of the motor, which can damage the motor if it is too great.
Do stepper motors run hot?
Stepper motors do get hot. Their cases can get up to about 100 – 110 degrees C. This is because the drive is supplying the motor with full current the whole time to keep the motor in position. The temperature difference of a stepper motor on and off of a heatsink can be up to 40 degrees C!
Which is not an advantage of stepper motor?
➨Resonance occurs if it is not properly controlled. ➨Progressive loss of torque at high speeds. Hence it is not easy to operate at extremely high speeds.
What happens when you lower the current on a stepper motor?
When you choose a lower current, you limit the speed because the motor will accelerate more slowly, requiring more time to get to the next step. Microstepping might be a little less efficient, but with smart controllers it is probably not much, and it will definitely “smooth out” vibration when running.
How can I choose the best power supply for my stepper motor?
In order to choose the best power supply for your stepper motor, you’ll need to add up the voltage of the motors. Just like most motors, stepper motors have a rated voltage and current. These numbers will tell you the maximum current you can expect when you hook the motor up to a certain voltage.
What happens if you mismatch the driver on a stepper?
Mismatched motors and drivers can result in disappointing performance. Or worse: damage to the motor and/or controller. Voltage – The maximum voltage that the driver can supply to the motor. Continuous Current – The maximum current that the driver can supply to the motor. “Peak” current ratings are not applicable to stepper motors.
What’s the difference between voltage and continuous current on a stepper?
Voltage – The maximum voltage that the driver can supply to the motor. Continuous Current – The maximum current that the driver can supply to the motor. “Peak” current ratings are not applicable to stepper motors. Always go by the “continuous” current rating.
