Stepper motor torque control, frequency, etc., to calculate the life of the stepper motor, how to count?
The service life of the stepper motor load and also a certain relationship with the application environment, the voltage of the power supply, for example, computer engraving machine to the higher supply voltage, the stepper motor current is large, high speed, large load, so the use of computer engraving machine stepper motor service life to within twenty thousand hours, in addition to bearing the loss caused by the high temperature of the motor, and the magnetic coil attenuation and ageing. In addition, some of the stepper motor application environment, high temperature, or oil, dust, water and other pollution, but also shorten the service life.
There are some ways to prolong the service life of stepping motors:1, maintain a good operating environment, pay attention to waterproof and dustproof, in the high temperature environment needs heat dissipation, in the low temperature environment, need to electrify preheating.2, when setting the drive current, do not input current greater than the rated current of the stepper motor.3, if the device does not require special, please select half flow lock, the stepper motor driver will have a static current option or default static half flow, reducing the heating of the stepper motor.
Stepper motor is characterized by small size, long life, usually depends on the life of bearings, the quality of qualified stepper motor can reach tens of thousands of hours.
