How do you measure the output current of the step motor driver
A series of current in one phase of the continuous running of the machine can be seen in one phase. In the phase line, the resistance of a single one in the phase line is used to see the waveform on both ends of the resistance, and the maximum on the oscilloscope is the peak current. The current, which is marked on the attachment of the appliance, or the current that the manufacturer stipulates that the attachment of the appliance can be carried by the specified conditions. Rated current of the electric equipment refers to the benchmark environment temperature, under the condition of rated voltage, fever is less than the long-term fever allowed temperature is allowed by the maximum current for a long time. Environment temperature, allows for a long time, maximum current has a great influence, due to the installation position of environmental temperature and temperature is not necessarily the same benchmark environment, generally as a rule: when the electric equipment work when the ambient temperature is higher than 40 degrees Celsius (but no higher than 60 degrees Celsius), environmental temperature, every 1 degree increase suggested that reduce the rated current 1.8%; When the temperature of the working environment is below 40 degrees, the temperature of the environment decreases by one degree, the recommended increase of 0.5 percent of the current rate, but the maximum of 20 percent of the rated current. For example, a 1mm2 copper conductor is rated at approximately 11A (30 degrees).
The continuous running time is related to the load, the current cannot be large when the load is on, and the rated current is achieved when the load is rated
